Hi Swapnil,

Please note that using RadAjaxManager simultaneously with RadAjaxPanel or UpdatePanel is not a supported scenario and we highly recommend to avoid such implementation.PLease try the sample code snippet.

ASPX:

<telerik:RadAjaxManager ID="RadAjaxManager1" EnableAJAX="true" runat="server">

<ClientEvents OnRequestStart="onRequestStart"></ClientEvents>

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadGrid1">

Hello Swapnil,

Note that it is not a supported scenario to use RadAjaxPanel and RadAjaxManager to update the same controls on the page or add RadAjaxPanel into RadAjaxManager settings. therefor please remove the RadAjaxPanel and use only RadAjaxManager to ajaxify the controls in order to avoid possible issues with the Ajax functionality.

Hi William,

If one and the same control is placed in RadAjaxPanel as well as included in RadAjaxManager settings as ajaxified control (i.e. it is ajaxified by both the panel and manager), the corresponding manager's setting will not work. In this case the AJAX Panel ajaxifies that control instead of the manager. RadAjaxPanel is designed to update only its content, therefore you can not use the manager to update other controls outside of the panel from control ajaxified by the manager and inside the RadAjaxPanel. In most cases using both control to update the same part of the page can lead to "Sys.WebForms.PageRequestManagerParserErrorException" error.
