'The Method or Operation is not Implemented' Eroor with RadAjaxManager

[Neelima]

I have a button 'btnSave', a ModalPopup 'mpuEditAddr', and a TabContainer 'tabGridview' with 2 panels each containing a gridview.

'mpuEditAddr' has two usercontrols 'uc_Address'

On btnSave Click I'm getting 'The method or operation is not implemented' error with the below code.
Any suggestions on where I'm going wrong would be greatly appreciated!!

I modified the RadAjaxManager part. Now I'm not getting the error  but when the RadGrid's SelectedIndex changes, ModalPopup 'mpuEditAddr' is expected to show up with the UserControl 'uc_Address' along with 'Update' and 'cancel' buttons.  But I see only the two buttons and not the UserControl.

Hi Neelima,

In order to isolate the issue further I would suggest that you comment any RadControls on the page. Make usre you are using an ASP:ScriptManager and ajaxify the page with ASP:UpdatePanel. Run the page and see if the problem persists. Thus we will see if the issue comes from any of the RadControls for ASP.NET AJAX or it is connected with the AjaxControlToolkit controls.

Best wishes,
