Toolbar in ASP.NET Core Grid control

The Grid provides ToolBar support to handle grid actions. The toolbar property accepts either the collection of built-in toolbar items and ItemModel objects for custom toolbar items or HTML element ID for toolbar template.

Built-in toolbar items

Built-in toolbar items execute standard actions of the grid, and it can be added by defining the toolbar as a collection of built-in items. It renders the button with icon and text.

The following table shows built-in toolbar items and its actions.

Built-in Toolbar Items Actions
Add Adds a new record.
Edit Edits the selected record.
Update Updates the edited record.
Delete Deletes the selected record.
Cancel Cancels the edit state.
Search Searches the records by the given key.
Print Prints the grid.
ExcelExport Exports the grid to Excel.
PdfExport Exports the grid to PDF.
WordExport Exports the grid to Word.

  • The toolbar has options to define both built-in and custom toolbar items.

Custom toolbar items

Custom toolbar items can be added by defining the toolbar as a collection of ItemModel. Actions for this customized toolbar items are defined in the toolbarClick event.

By default, Custom toolbar items are in position Left. You can change the position by using the align property. In the below sample, we have applied position Right for the Collapse All toolbar item.

tagHelper
custom-toolbar-item.cs
@{

    List<object> toolbarItems = new List<object>();
    toolbarItems.Add(new { text = "Expand All", tooltipText = "Expand All", prefixIcon = "e-expand", id = "expandall" });
    toolbarItems.Add(new { text = "Collapse All", tooltipText = "Collapse All", prefixIcon = "e-collapse", id = "collapseall", align = "Right" });
}

<ejs-grid id="Grid" dataSource="@ViewBag.datasource" toolbarClick="toolbarClick" toolbar=toolbarItems height="270" allowGrouping="true">
    <e-grid-groupsettings columns="@(new string[] {"CustomerID"})"></e-grid-groupsettings>
    <e-grid-columns>
        <e-grid-column field="OrderID" headerText="Order ID" type="number" textAlign="Right" width="120"></e-grid-column>
        <e-grid-column field="CustomerID" headerText="Customer ID" type="string" width="140"></e-grid-column>
        <e-grid-column field="Freight" headerText="Freight" textAlign="Right" format="C2" width="120"></e-grid-column>
        <e-grid-column field="OrderDate" headerText="Order Date" format='yMd' textAlign="Right" width="140"></e-grid-column>
    </e-grid-columns>
</ejs-grid>

<script>
    function toolbarClick(args) {

        if (args.item.id === 'expandall') {
            this.groupModule.expandAll();
        }
        if (args.item.id === "collapseall") {
            this.groupModule.collapseAll();
        }

    }
</script>
public IActionResult Index()
 {
    var orders = orderDetails.GetAllRecords();
    ViewBag.datasource = orders;            
    return View();
 }
  • The toolbar has options to define both built-in and custom toolbar items.
  • If a toolbar item does not match the built-in items, it will be treated as a custom toolbar item.

Built-in and custom items in toolbar

Grid have an option to use both built-in and custom toolbar items at same time.

In the below example, Add, Edit, Delete, Update, Cancel are built-in toolbar items and Click is custom toolbar item.

tagHelper
builtin-custom-items.cs
@{
    List<object> toolbarItems = new List<object>();
    toolbarItems.Add("Add");
    toolbarItems.Add("Edit");
    toolbarItems.Add("Delete");
    toolbarItems.Add("Update");
    toolbarItems.Add("Cancel");
    toolbarItems.Add(new { text = "Click", tooltipText = "Click", prefixIcon = "e-expand", id = "Click" });
}

<div>
    <ejs-grid id="Grid" dataSource="@ViewBag.DataSource" allowResizing="true" allowPaging="true" allowSorting="true" toolbarClick="toolbarClick" toolbar=toolbarItems>
        <e-grid-editSettings allowAdding="true" allowDeleting="true" allowEditing="true" mode="Normal"></e-grid-editSettings>
        <e-grid-columns>
            <e-grid-column field="OrderID" headerText="Order ID" isPrimaryKey="true" width="120"></e-grid-column>
            <e-grid-column field="EmployeeID" headerText="Employee ID" width="120"></e-grid-column>
            <e-grid-column field="Freight" headerText="Freight" format="C2" width="120"></e-grid-column>
            <e-grid-column field="ShipCity" headerText="Ship City" editType="dropdownedit" edit="new {@params = new { dataSource= ViewBag.DropdownData} }" width="120"></e-grid-column>
            <e-grid-column field="ShipCountry" headerText="Ship Country" width="120"></e-grid-column>
        </e-grid-columns>
    </ejs-grid>
</div>

<script>
    function toolbarClick(args) {
        if (args.item.id === 'Click') {
            alert("Custom toolbar click...");
        }
    }
</script>

<style>
    .e-expand::before {
        content: '\e5b8';
    }
</style>
public IActionResult Index()
 {
   var orders = OrderDetails.GetAllRecords();
   ViewBag.DataSource = orders;            
   return View();
 }

Enable/disable toolbar items

You can enable/disable toolbar items by using the enableItems method.

tagHelper
enable-disable.cs
<ejs-button id="disable" content="Disable"></ejs-button>
<ejs-button id="enable" content="Enable"></ejs-button>
<ejs-grid id="Grid" dataSource="@ViewBag.datasource" toolbarClick="toolbarClick" toolbar="@( new List<string>(){"Expand","Collapse"})" height="270" allowGrouping="true">
    <e-grid-columns>
        <e-grid-column field="OrderID" headerText="Order ID" type="number" textAlign="Right" width="120"></e-grid-column>
        <e-grid-column field="CustomerID" headerText="Customer ID" type="string" width="140"></e-grid-column>
        <e-grid-column field="Freight" headerText="Freight" textAlign="Right" format="C2" width="120"></e-grid-column>
        <e-grid-column field="OrderDate" headerText="Order Date" format='yMd' textAlign="Right" width="140"></e-grid-column>
    </e-grid-columns>
    <e-grid-groupSettings columns="@(new string[] { "CustomerID"})"></e-grid-groupSettings>
</ejs-grid>

<script>
    document.getElementById("enable").addEventListener('click', () => {
        var grid = document.getElementById("Grid").ej2_instances[0];
        grid.toolbarModule.enableItems(['Grid_Collapse', 'Grid_Expand'], true);// enable toolbar items.
    });

    document.getElementById("disable").addEventListener('click', () => {
        var grid = document.getElementById("Grid").ej2_instances[0];
        grid.toolbarModule.enableItems(['Grid_Collapse', 'Grid_Expand'], false);// disable toolbar items.
    });

    function toolbarClick(args) {
        if (args.item.id === 'Grid_Collapse') { // grid_Collapse is component id + '_' + toolbar item name.
            this.groupModule.collapseAll();
        }
        if (args.item.id === 'Grid_Expand') {
            this.groupModule.expandAll();
        }
    }
</script>
public IActionResult Index()
 {
   var orders = orderDetails.GetAllRecords();
   ViewBag.datasource = orders;            
   return View();
