Could not be found for the trigger in UpdatePanel

I'm having a problem refresing the data in a gridview which is contained within an update panel.

I keep getting the error
A control with ID 'GridIVRecs' could not be found for the trigger in UpdatePanel 'UpdatePanel7'.

A control with ID 'GridIVRecs' could not be found for the trigger in UpdatePanel 'UpdatePanel7'.

I think it maybe something to do with the update panels being in different tab containers

Hi,

Yes, i think so that will be the problem.

So Keep the GridView in the same tab and try.

Hi

I found the solution.  You have to reference the tabcontainername$tabpanelname before the control name.

Like this

 <asp:AsyncPostBackTrigger ControlID="tcIQA1$tpIQA$GridIVRecs"  />
                             <asp:AsyncPostBackTrigger ControlID="tcIQADetail$tpIQADETAIL1$btnDefaults"  />
                               <asp:AsyncPostBackTrigger ControlID="tcIQADetail$tpIQADETAIL1$btnSaveIVRecord"  />

Open in new window


All works perfectly now.

Thanks
