    i have two RadWindows, and i am using RadAjaxManager1_AjaxRequest   to update a DIV on OnClientClose event of RadWindow1. This works, but RadWindow2 also triggers this event and causes it to error. can someone help me with this issue. the div is inside an update panel and it still errors. This is the error i get

    Error: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00_MP_CPH1_ctl00_MP_CPH1_dv_PreviewPanel'. If it is being updated dynamically then it must be inside another UpdatePanel.

    i attached an image for the code snippets, any help is appreciated. Thank you.

    Murali.

    Hello Murali,

    This can be due to a double ajaxification of the said div - please make sure your settings do not include it incorrectly twice as nested update panels is an inherently problematic AJAX scenario. Also, does this behavior occur only when used with the RadWindow or also on a click of a simple button, for example. Can you also confirm that there are no other AJAX requests pending at the time, as they would dispose this object and thus the functions may not be able to find it. Also, is this content moved in the DOM via JavaScript?
