i am using a popup web control as the edit form for my rad grid. i added  a RadAjaxLoadingPanel and a RadAjaxManager to display progress for a slow-loading combobox. now, when i attempt to close or click "cancel" in my web control i get the error below:

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: A control with ID 'ctl00$ContentPlaceHolder1$RadGridProductionOrders$ctl00$ctl06$Detail10$ctl12$EditFormControl$RadComboBoxItemCodeFilters' could not be found for the trigger in UpdatePanel 'ctl00$ContentPlaceHolder1$RadGridProductionOrders$ctl00$ctl06$Detail10$ctl12$EditFormControl$PanelMainPanel'.

Hi Nicos,

           If you use two ajax manager on your main page and popup you'll get that error. Please check this doc. RadControls for ASP.NET AJAX Documentation.



Hope this help.

Alex

thanks, that worked, i replaced the RadAjaxManager with a RadAjaxManagerProxy, but now the loading panel does not appear. are you able to just copy the markup from within the <AjaxSettings> block from the RadAjaxManager to the RadAjaxManagerProxy?

Hi,

You could check this online demo application which demonstrates scenario with RadAjaxManagerProxy and RadAjaxLoadingPanel.

If this does not help you resolve the issue, please, share your full page code including the code-behind.
All the best,
