Customize ListView as Chat Window
17 Feb 202215 minutes to read
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>" +
"${/if}" +
"</div>";Chat order in template
In ListView template, we have rendered the list items based on receiver and sender information from dataSource of listview.
Adding messages to chat window
* Use textbox to get message from user.
* Add the textbox message to ListView dataSource using [addItem](https://ej2.syncfusion.com/documentation/api/list-view/#additem) method.
document.getElementById('btn').addEventListener('click', (e) => {
var value = document.getElementById('name').value;
document.getElementById('List').ej2_instances[0].addItem([{ text: "Amenda", contact: value, id: "2", avatar: "A", pic: "", chat: "receiver" }]);
});@{
var template = "<div class='settings'>" +
"${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>" +
