Use dynamic templates of ListView based on device

The Syncfusion Essential JS2 components are desktop and mobile-friendly. So, you can use Syncfusion components in both modes. The component templates are not always fixed. Applications may need to load various templates depending upon the device.

Integration

In the ListView component, template support is being used. In some cases, the component wrapper is always responsive across all devices, but the template contents are dynamically changed with unspecified (sample side) dimensions. CSS customization is also needed in sample-side to align template content responsively in both mobile and desktop modes. Here, two templates have been loaded for mobile and desktop modes. To check the device mode, a browser module has been imported from the ej2-base package.

Customize dual list

The dual list contains two ListView. This allows you to move list items from one list to another using the client-side events. This section explains how to integrate the ListView component to achieve dual list.

Use cases

Stock exchanges of two different countries
Job applications (skill sets)

Integration of Dual List

Here, two ListView components have been used to display the list items. An ej2-button is used to transfer data between the ListView, and a textbox is used to achieve the UI of filtering support.

The dual list supports:

Moving whole data from one list to another.
Moving selected data from one list to another.
Filtering the list by using a client-side typed character.

In the ListView component, sorting is enabled using the sortOrder property, and the select event is triggered while selecting an item. Here, the select event is triggered to enable and disable button states.

Manipulating data

Moving whole data from the first list to the second list(>>)

Here, the whole data can be moved from the first ListView to the second by clicking the first button. When clicking the button, the whole list items are sliced, and concat with the second ListView. This button is enabled only when the data source of the first ListView is not empty.

Moving whole data from the second list to the first list(<<)

The functionality of the second button is the same as above, and data is transferred from the second list to the first list. This button is enabled only when the data source of the second ListView is not empty.

Moving selected item from one list to another list (>) and (<)

The Select event is triggered when selecting a list item in the ListView. The selected items can be transferred between two lists. These buttons will be enabled when selecting an item in lists.

Filtering method

The filtering method is used to filter list items when typing a character in the text box. In this method, the dataManager has been used to fetch data from the data source and display in ListView.

Sorting

By using the dual list, list items can be sorted in the ListView component using the sortOrder property. You can enable sorting in one ListView; in the same order, data can be transferred to another ListView.

Load list items in child list dynamically

To load list items in child list dynamically, push the new list item data into the existing dataSource using the select event.

Refer to the following steps to load list item into the child list:

Initially, render the ListView with the required data source.
Bind the select event that triggers selecting list item in the ListView component. By using the select event, you can push the new list item to the child list of the data source on specifying its item index. Item index can be obtained from the SelectEventArgs of the select event.

List Items Count in Group Header

The ListView component supports wrapping list items into a group based on the category. The category of each list item can be mapped with groupBy field of the data source. You can display grouped list items count in the list-header using the group header template. Refer to the following code sample to display grouped list item count.

razor

list.cs

@using Syncfusion.EJ2
@using Syncfusion.EJ2.Lists;

    var template = "<div class='settings'>"
    + "<div id='postContainer'><div id='postImg'>"
    + "<img src=${image} style='height:35px;width:35px;border-radius:50%; border: 1px solid #ccc;' /></div>"
    + "<div id='content'><div class='name'>${Name}</div><div id='info'>${contact}</div></div></div>";
}
@Html.EJS().ListView("List").DataSource((IEnumerable<object>)ViewBag.dataSource).Fields(new ListViewFieldSettings { GroupBy = "category", Text = "Name" }).GroupTemplate("<div><span class='category'>${items[0].category}</span> <span class='count'> ${items.length} Item(s)</span></div>").Template(template).Render()

            ViewBag.dataSource = listdata;
            return View();
        }
    }
}

The filtered data can be displayed in the ListView component depending upon on user inputs using the DataManager. Refer to the following steps to render the ListView with filtered data.

Render a textbox to get input for filtering data.
Render ListView with dataSource, and set the sortOrder property.
Bind the keyup event for textbox to perform filtering operation. To filter list data, pass the list data source to the DataManager, manipulate the data using the executeLocal method, and then update filtered data as ListView dataSource.

In this demo, data has been filtered with starting character of the list items. You can also filter list items with ending character by passing the endswith in where clause instead of startswith.

Add and remove list items from the ListView component

You can add or remove list items from the ListView component using the addItem and removeItem methods. Refer to the following steps to add or remove a list item.

Render the ListView with data source, and use the template property to append the delete icon for each list item. Also, bind the click event for the delete icon using the actionComplete handler.
Render the Add Item button, and bind the click event. On the click event handler, pass data with random id to the addItem method to add a new list item on clicking the Add Item button.
Bind the click handler to the delete icon created in step 1. Within the click event, remove the list item by passing the delete icon list item to removeItem method.

Trace all events in ListView

The ListView component triggers events based on its actions. The events can be used as extension points to perform custom operations. Refer to the following steps to trace the ListView events:

Render the ListView with dataSource, and bind the actionBegin, actionComplete, and select events.
Perform custom operations in actionBegin, actionComplete, and select events.
Provide event log details for actionBegin and actionComplete events, and they will be displayed in the event trace panel when the ListView action starts and the dataSource bound successfully.
Get the selected item details from the SelectEventArgs in the select event, and display the selected list item text in the event trace panel while selecting list items.
Use clear button to remove event trace information.

Customize ListView as mobile contact layout

You can customize the ListView using the template property. Refer to the following steps to customize ListView as mobile contact view with our ej2-avatar.

Render the ListView with dataSource that has avatar data. You can set avatar data as either text or class names. Refer to the following codes.

    List<object> listdata = new List<object>();
    listdata.Add(new
    {
        text = "Jenifer",
        contact = "(206) 555-985774",
        id = "1",
        avatar = "",
        pic = "pic01"
    });
        listdata.Add(new
    {
        text = "Amenda",
        contact = "(206) 555-3412",
        id = "2",
        avatar = "A",
        pic = ""
    });

Set avatar classes in ListView template to customize contact icon. In the following codes, medium size avatar has been set using the class name e-avatar e-avatar-circle from data source.

  var template: "<div class='settings'>" +
            "${if(avatar!=='')}" +
            "<span class='e-avatar e-avatar-circle'>${avatar}</span>" +
            "${else}" +
            "<span class='${pic} e-avatar e-avatar-circle'> </span>" +
            "${/if}" +
            "<div id='content'>" +
            "<div class='name'>${text}</div>" +
            "<div id='info'>${contact}</div>" +
            "</div>";

Avatars can be set in different sizes in avatar classes. To know more about avatar classes, refer to Avatar.

Sort the contact names using the sortOder property of ListView.
Enable the showHeader property, and set the headerTitle as Contacts.

            ViewBag.dataSource = listdata;
            return View();
        }
    }
}

Load the spinner until list items are loaded

The features of the ListView component such as remote data-binding take more time to fetch data from corresponding dataSource/remote URL. In this case, you can use EJ2 Spinner to enhance the appearance of the UI. This section explains how to load a spinner component to groom the appearance.

Refer to the following code sample to render the spinner component.

    ej.popups.createSpinner({
        target: document.getElementById('spinner')
    });
    ej.popups.showSpinner(document.getElementById('spinner'));

Refer to the following code sample to render the ListView component.

<!-- ListView element -->
@Html.EJS().ListView("element").DataSource(dataManger =>
{dataManger.Url("http://js.syncfusion.com/ejServices/Wcf/Northwind.svc/").CrossDomain(true);
}).Query("new ej.data.Query().from('Products').select('ProductID,ProductName').take(10)").ActionBegin("onBegin").Fields(new ListViewFieldSettings { Id = "ProductID", Text = "ProductName" }).ShowHeader(true).HeaderTitle("Product Name").Width("300").ActionComplete("oncomplete").Render()

Here, the data is fetched from Northwind Service URL; it takes a few seconds to load the data. To enhance the UI, the spinner component has been rendered initially. After the data is loaded from remote URL, the spinner component will be hidden in ListView actionComplete event.

razor

list.cs

@using Syncfusion.EJ2
@using Syncfusion.EJ2.Lists;
<!-- ListView element -->
@Html.EJS().ListView("element").DataSource(dataManger =>
{dataManger.Url("http://js.syncfusion.com/ejServices/Wcf/Northwind.svc/").CrossDomain(true);
}).Query("new ej.data.Query().from('Products').select('ProductID,ProductName').take(10)").ActionBegin("onBegin").Fields(new ListViewFieldSettings { Id = "ProductID", Text = "ProductName" }).ShowHeader(true).HeaderTitle("Product Name").Width("300").ActionComplete("oncomplete").Render()

<style>
    #element {
        display: block;
        max-width: 350px;
        min-height: 200px;
        margin: auto;
        border: 1px solid #dddddd;
        border-radius: 3px;
    }
</style>
<script>
    function oncomplete() {
        document.getElementById('spinner').style.display = "none";
    }
    function onBegin() {
        var ele = document.createElement('div');
        ele.id = 'spinner';
        document.getElementById('element').appendChild(ele);
        ej.popups.createSpinner({
            target: document.getElementById('spinner')
        });
        ej.popups.showSpinner(document.getElementById('spinner'));
    }
</script>

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;

namespace WebApplication1.Controllers
{
    public class ListViewController : Controller
    {
        public IActionResult list()
        {   
            return View();
        }       
    }
}

Hide checkbox in listview

The checkbox of the any list item can be hidden by using htmlAttributes of fields object. With the help of htmlAttributes we can add unique class to each list item that will be rendered from the data source, from the CSS class we can hide the checkbox of the list item.

In this sample, we had hidden the multiple leaf node of nested list. The e-checkbox-hidden class has been added in the data source where the checkbox needs to be hidden. Refer the below snippet for simple data source.

    {
        text= 'New York',
        id= '3002',
        category= 'USA',
        htmlAttributes= { 'class': 'e-file e-checkbox-hidden' }
    }

Even though we have hidden the checkbox the functionality will be same for the list item which might affect the getSelectedItems method. So, to counteract that we will follow certain logic in the select event. The Logic here is to remove the e-active class from the other checkbox hidden list item which will be added when we select on that item and retain e-active on currently selected item.

In this process we will exclude the visible checkbox list items and only consider the hidden checkbox items.

razor

list.cs

@using Syncfusion.EJ2
@using Syncfusion.EJ2.Lists;
<!-- ListView element -->
@Html.EJS().ListView("folderCheckbox").DataSource((IEnumerable<object>)ViewBag.dataSource).Fields(new ListViewFieldSettings { Tooltip = "text" }).ShowHeader(true).HeaderTitle("Mixed Leaf Checkbox Hidden List").ShowCheckBox(true).Select("onSelect").Render()

<style>
    #folderCheckbox {
        border: 1px solid #dddddd;
        border-radius: 3px;
        width: 350px;
        margin: auto;
    }

    #folderCheckbox .e-checkbox-hidden .e-checkbox-wrapper {
        visibility: hidden;
    }
</style>
<script>
    function onSelect(args) {
        var listviewInstance = document.getElementById("folderCheckbox").ej2_instances[0];
        // Selecting all the e-active elements from the list.
        var normalElements = Array.prototype.slice.call(listviewInstance.element.getElementsByClassName('e-checkbox-hidden'));

        // Looping through all the selected element and removing e-active class
        // to avoid behaviour interference  with getSelectedItems method
        normalElements.forEach((element) => {
            element.classList.remove('e-active');
        });

        // Finally adding e-active class to currently selected item except checkbox item.
        // because if it is checkbox item their actions will taken care from the source side itself.
        if (args.item.classList.contains('e-checkbox-hidden')) {
            args.item.classList.add('e-active');
        }
    }

ListView manipulation in grid layout

In Listview, list items can be rendered in grid layout with following data manipulations.

Add Item
Remove Item
Sort Items
Filter Items

Grid Layout

In this section, we will discuss about rendering of list items in grid layout.

Initialize and render ListView with dataSource which will render list items in list layout.
Now, add the below CSS to list item. This will make list items to render in grid layout

#element .e-list-item {
        height: 100px;
        width: 100px;
        float: left;
}

In the below sample, we have rendered List items in grid layout.

razor

list.cs

@using Syncfusion.EJ2
@using Syncfusion.EJ2.Lists;
@{
    var template = "<img id='listImage' src='./apple.png' alt='apple' />";
}

<!-- ListView element -->
@Html.EJS().ListView("element").DataSource((IEnumerable<object>)ViewBag.dataSource).Template(template).Render()

<style>

#element {
    display: block;
    max-width: 303px;
    margin: auto;
    border: 1px solid #dddddd;
    border-radius: 3px;
}

#element .e-list-item {
    height: 100px;
    width: 100px;
    float: left;
    padding: 0;
}

#listImage {
    width: 55px;
    height: 55px;
    margin-left: 20px;
    margin-top: 20px;

}

</style>

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;

namespace WebApplication1.Controllers
{
    public class ListViewController : Controller
    {
        public IActionResult list()
        {   
            string[] listdata = { "1","2", "3", "4", "5", "6", "7", "8", "9" };
            ViewBag.dataSource = listdata;
            return View();
        }       
    }
}

Data manipulation

In this section, we will discuss about ListView data manipulations.

Add Item

We can add list item using addItem API. This will accept array of data as argument.

 listViewInstance.addItem([{text: 'Apricot', id: '32'}]);

In the below sample, you can add new fruit item by clicking add button which will open dialog box with fruit name and image URL text box. After entering the item details, click the add button. This will add your new fruit item.

Remove item

We can remove list item using removeItem API. This will accept fields with id or list item element as argument.

 listViewInstance.removeItem({id: '32'});

In the below sample, you can remove fruit by hovering the fruit item which will show delete button and click that delete button to delete that fruit from your list.

Sort Items

Listview can be sorted either in Ascending or Descending order. To enable sorting in your ListView, set sortOrder as Ascending or Descending.

@Html.EJS().ListView("element").SortOrder(SortOrder.Ascending).Render()

We can also set sorting after component initialization.

listViewInstance.sortOrder = 'Ascending'

In the below sample, we have sorted fruits in Ascending order. To sort it in descending, click on sort order icon and vice versa.

razor

list.cs

@using Syncfusion.EJ2
@using Syncfusion.EJ2.Lists;
@using Syncfusion.EJ2.Popups;
@{
    var template = "<div class='fruits'><div class='first'><img id='listImage' src='${ imgUrl}' alt='fruit' /><button class='delete e-control e-btn e-small e-round e-delete-btn e-primary e-icon-btn' data-ripple='true'><span class='e-btn-icon e-icons delete-icon'></span></button></div><div class='fruitName'>${text}</div></div>";
}
<div id="container">
    <div class="headerContainer">
        <div class="e-input-group">

Filter Items

Listview data can be filtered with the help of dataManager. After filtering the data, update ListView dataSource with filtered data.

var value = document.getElementById("filter").value;  //input text box value
var filteredData = new ej.data.DataManager(listdata).executeLocal(
        new ej.data.Query().where("text", "startswith", value, true)
);

listViewInstance.dataSource = filteredData;

In the below sample, we can filter fruit items with the help of search text box. This will filter fruit items based on your input. Here we used startswith of input text to filter data in DataManager.

razor

list.cs

@using Syncfusion.EJ2
@using Syncfusion.EJ2.Lists;
@{
    var template = "<img id='listImage' src='./apple.png' alt='apple' />";
}

<!-- ListView element -->

ListView with Drag and Drop feature (Reorder)

In ListView component, we don’t have drag and drop support. But we can achieve this requirement using TreeView component with ListView appearance.

Drag and Drop in TreeView component was enabled by setting allowDragAndDrop to true.

@Html.EJS().TreeView("element").Fields(ViewBag.TreeViewFields).AllowDragAndDrop(true).Render()

The TreeView component is used to represent hierarchical data in a tree like structure. So, list items in TreeView can be dropped to child of target element. we can prevent this behaviour by cancelling the nodeDragStop and nodeDragging events.

@Html.EJS().TreeView("element").Fields(ViewBag.TreeViewFields).AllowDragAndDrop(true).NodeDragging("onDragStop").NodeDragStop("onDragStop").Render()

function onDragStop(args) {
    //Block the Child Drop operation in TreeView
   var  draggingItem = document.getElementsByClassName("e-drop-in");
    if (draggingItem.length == 1) {
        draggingItem[0].classList.add('e-no-drop');
        args.cancel = true;
    }
}

In the below sample, we have rendered draggable list items.

razor

list.cs

@using Syncfusion.EJ2
@using Syncfusion.EJ2.Lists;
using Syncfusion.EJ2.Navigations;
@Html.EJS().TreeView("element").Fields(ViewBag.TreeViewFields).AllowDragAndDrop(true).NodeDragging("onDragStop").NodeDragStop("onDragStop").Render()

<style>
    #element.e-treeview .e-ul {
        padding: 0;
    }

    #element.e-treeview .e-list-item {
        padding: 0 16px;
    }

    #element.e-treeview .e-text-content {
        padding: 0;
    }

    #element.e-treeview .e-fullrow {
        height: 36px;
    }

    #element.e-treeview .e-list-text {
        line-height: 34px;
    }

    #element.e-treeview .e-list-item:last-child {
        margin-bottom: 9px;
    }

    #element.e-treeview .e-list-item:first-child {
        margin-top: 9px;
    }
</style>
<script>
    function onDragStop(args) {
        //Block the Child Drop operation in TreeView
        var draggingItem = document.getElementsByClassName("e-drop-in");
        if (draggingItem.length == 1) {
            draggingItem[0].classList.add('e-no-drop');
            args.cancel = true;

            ViewBag.dataSource = listdata;
            return View();
        }       
    }
}

We can use anchor tag along with href attribute in our ListView template property for navigation.

var anchor_template = "<a target='_blank' href='${url}'>${name}</a>";

In the below sample, we have rendered ListView with search engines URL.

razor

list.cs

@{
    var anchor_template = "<a target='_blank' href='${url}'>${name}</a>";
}
@using Syncfusion.EJ2
@using Syncfusion.EJ2.Lists;
@Html.EJS().ListView("element").DataSource((IEnumerable<object>)ViewBag.dataSource).Template(anchor_template).HeaderTitle("Search engines").ShowHeader(true).Render()

<style>
    #element {
        display: block;
        max-width: 350px;
        margin: auto;
        border: 1px solid #dddddd;
        border-radius: 3px;
    }

    #element a {
        text-decoration: none;
    }

    #element .e-list-header {
        background: rgb(2, 120, 215);
        color: white;
        font-size: 19px;
        font-weight: 500;
    }
</style>

{
    public class ListViewController : Controller
    {
        public IActionResult list()
        {   
            List<object> listdata = new List<object>();
            listdata.Add(new { name = "Google", url = "https://www.google.com" });
            listdata.Add(new { name = "Bing", url = "https://www.bing.com" });
            listdata.Add(new { name = "Yahoo", url = "https://www.yahoo.com" });
            listdata.Add(new { name = "Ask.com", url = "https://www.ask.com" });
            listdata.Add(new { name = "AOL.com", url = "https://www.aol.com"});
            ViewBag.dataSource = listdata;
            return View();
        }       
    }
}

Customize ListView as Chat Window

ListView can be customized as chat window. To achieve that, use the ListView template property and Avatar component.

* The Listview template property is used to showcase the ListView as chat window.
* Avatar component is used to design the image of contact person.

Refer the below template code snippet for Template of chat window.

var template = "<div class='settings'>" +
                "${if(chat!=='receiver')}" +
                "<div id='content'>" +
                "<div class='name'>${text}</div>" +
                "<div id='info'>${contact}</div></div>" +
                "${if(avatar!=='')}" +
                "<div id='image'><span class='e-avatar img1 e-avatar-circle'>${avatar}</span></div>" +
                "${else}" +
                "<div id='image'><span class='${pic} img1 e-avatar e-avatar-circle'> </span></div>" +
                "${/if}" +
                "${else}" +
            "${if(avatar!=='')}" +
                "<div id='image2'><span class='e-avatar img2 e-avatar-circle'>${avatar}</span></div>" +
                "${else}" +
                "<div id='image2'><span class='${pic} img2 e-avatar e-avatar-circle'> </span></div>" +
                "${/if}" +
                "<div id='content1'>" +
                "<div class='name1'>${text}</div>" +
                "<div id='info1'>${contact}</div>" +
                "</div>" +
                "${/if}" +
                "</div>";

Chat order in template

In ListView template, we have rendered the list items based on receiver and sender information from dataSource of listview.

Adding messages to chat window

* Use textbox to get message from user.
* Add the textbox message to ListView dataSource using [addItem](https://ej2.syncfusion.com/documentation/listview/api-listView.html?lang=typescript#additem) method.

document.getElementById('btn').addEventListener('click', (e) => {
    var value = document.getElementById('name').value;
     document.getElementById('List').ej2_instances[0].addItem([{ text: "Amenda", contact: value, id: "2", avatar: "A", pic: "", chat: "receiver" }]);
  });

razor

list.cs

@{
    var template = "<div class='settings'>" +
                     "${if(chat!=='receiver')}" +
                      "<div id='content'>" +
                      "<div class='name'>${text}</div>" +
                      "<div id='info'>${contact}</div></div>" +
