Export to PDF when Grid in an UPdatePanel and Tab Control

[Debbie]

I read an old post on the forum that explains what is needed when the RadGrid is contained within an Update Panel in order for the export functionality to work.
(http://www.telerik.com/help/aspnet-ajax/grdexportwithajax.html).

So I added the Triggers to the UpdatePanel but this didn't work since my Grid (and export button) was contained within a tab of a Tab Control

This resulted in error:
A control with ID 'btnExport' could not be found for the trigger in UpdatePanel 'upTabs'.

For a workaround I had to move the Export button outside of the tabcontrol but this isn't the desired behavior.

Any suggestions?

Thanks!
Debbie

Hi Debbie,

You can use RadAjaxManager or RadAjaxPanel instead. In these two controls you have OnRequestStart event where you can cancel the ajax call conditionally. Please check these examples for more info:
