The OnTypingStart client-side event fires when the user starts typing in the chat message box. The event is fired only once, and not upon each keystroke. Equal to the typingStart event of the underlying Kendo UI Chat widget.

The event handler receives two parameters:

  1. The Chat instance firing the event.
  2. An object with the following methods:
    1. get_sender() - the Kendo UI Chat widget instance which fired the event;
<script type="text/javascript">
    function onTypingStart(sender, args) {
        var chat = sender;     
<telerik:RadChat runat="server" ID="RadChat1">
    <ClientEvents OnTypingStart="onTypingStart" />
