Some postbacks from dynamic controls are ignored

[Dan Lehmann]

I'm using 2011_2_712 and have Uploaded a project here.

I'm using a RadTabStrip to dynamically load various User Controls. Events on these user controls sometimes take multiple firings for them to land on the event handlers.

To see this,
1. Put a breakpoint on the Select statement of rgOrders_ItemCommand()
2. Navigate to Default.aspx
3. Press "Select" for one of the customers. (The first one, Alfreds Futterkiste has orders)
4. Click the Orders tab.
5. Click Select for one of the orders.
Notice the postback is lost.

6. Press Select again and the postback is correct.

In my real project it takes 2 postbacks for one telerik control and 3 for another.  Can anyone make sense of this or tell me what I'm doing wrong?

Thanks,
Dan

Found the solution here: http://www.velocityreviews.com/forums/t71158-events-not-firing-first-time-only-in-a-dynamic-user-control-please-help.html

Apparently ID's are required.. I fixed by adding the id like:

Private Function GetControl(ByVal index As Int32) As UserControl

    Dim ctrl As UserControl = Nothing

    Select Case index

        Case 0

            ctrl = LoadControl("Controls/Customer.ascx")

        Case 1

            ctrl = LoadControl("Controls/Orders.ascx")

           


    End Select
     ctrl.ID = "ucID" & index


    Return ctrl

End Function

Thanks,
