Trygve asked on 09 Mar 2009, 09:04 AM

I am trying to implement a solution based around the Load On Demand example for the tabstrip. I have 4 tabs, and each tab contains a grid. I have configured the grid which is loaded in the first initial tab with some events in ItemDataBound. But when I click one of the other tabs, and then click back to the first tab the events which happend in ItemDataBound is gone. And to get them back I need to trigger an event which rebinds the grid. Am I missing something here? Should I do the events in the ItemDataBound somewhere else?

Some method and irrelevant code has been removed, but that code has no effect on the grid or anything else. afAccessLayer.ExecProcedure is a custom written method of executing stored procedures, so is everything else called using afAccessLayer. But they basicly do the same as regular calls, so they dont affect the result given.

Any help in locating what's removing the images which was added in ItemDataBound is appreciated.

Thanks,
