How to set Client Events on RadAjaxManager programmatically?

[Darius]

Hi, I am trying to set the OnRequestStart client event of RadAjaxManager from server side. I tried this code, but it's not firing the event:

RadAjaxManager.GetCurrent(Page).ClientEvents.OnRequestStart = "mngRequestStarted";

I am ajaxifying the control properly with:

<telerik:RadAjaxManager ID="MasterAjaxManager" runat="server">
<AjaxSettings>
     <telerik:AjaxSetting AjaxControlID="MasterAjaxManager">
<UpdatedControls>
     <telerik:AjaxUpdatedControl ControlID="grdTest" />
 
</UpdatedControls>
</telerik:AjaxSetting>
</AjaxSettings>
</telerik:RadAjaxManager>

function mngRequestStarted(ajaxManager, eventArgs)
{

//this Is never getting called
      alert("eventFired");

}

Hello,

Try to place the JavaScript function inside telerik:RadScriptBlock tags:

<telerik:RadScriptBlock  ID="RadScriptBlock1" runat="server">
function mngRequestStarted(ajaxManager, eventArgs) {
      alert("eventFired");
} 
</telerik:RadScriptBlock >

Check this article for more information: https://docs.telerik.com/devtools/aspnet-ajax/controls/ajaxmanager/radcodeblock-and-radscriptblock.

Also try to put the script on the page with the RadAjaxManager on it.

Best regards,
Rumen
