The OnResponseEnd client-side event handler is called when a request is received from the server. The event can not be cancelled.

Two parameters are passed to the event handler with the following methods:

  • sender - The instance of the client-side RadAjaxManager /RadAjaxPanel object.

  • eventArgs , which has the following methods:

  • get_eventTarget() - Gets the UniqueID of the element that had raised the request.

  • get_eventArgument() - Gets the string passed in the initial AJAX request.

  • get_eventTargetElement() - Gets the instance of the client-side object that raised the AJAX request.

The following example displays the control that initiated the request.

<script type="text/javascript">
    function responseEnd(sender, eventArgs) {
        alert('Response end initiated by: ' + eventArgs.get_eventTarget());
<telerik:RadScriptManager ID="RadScriptManager1" runat="server">
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
    <ClientEvents OnResponseEnd="responseEnd" />
