OnAjaxRequest

The AjaxRequest event occurs when triggered by the client-side ajaxRequest() function or the server-side `RaisePostBackEvent()`` method.

The event cannot be cancelled. The AjaxRequest event handler receives a single string argument.

The example below demonstrates an AjaxRequest triggered from both the client and server. An a HTML input button and a standard ASP.NET button are also defined. The HTML input button triggers a function that calls the client-side ajaxRequest(). The ASP.NET button triggers a server-side OnClick event that in turn calls the RaisePostBackEvent() method.

ASP.NET

<form id="form1" runat="server">
<telerik:RadScriptManager ID="RadScriptManager1" runat="server">
</telerik:RadScriptManager>
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">
</telerik:RadAjaxManager>
<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
	<script type="text/javascript">
	    function clientClick() {
	        var ajaxManager = $find("<%= RadAjaxManager1.ClientID %>");
	        ajaxManager.ajaxRequest("client");
	    }
	</script>
</telerik:RadCodeBlock>
<div>
	<asp:Button ID="btnServer" runat="server" Text="Make server AjaxRequest" OnClick="btnServer_Click" />
	<input id="btnClient" type="button" value="Make client AjaxRequest" onclick="clientClick();" />
</div>
</form>

{
	RadAjaxManager1.Alert("AjaxRequest raised from the " + e.Argument);
}
