• I have a grid with 5 rows.
• If two users access the same grid at the same time from different machines.
• the first user delete the 3rd record.
• the second user click the edit button to edit the 3rd record.
• the problem is that the grid put the 4th row in edit mode because the 3rd one  really deleted.
• This is a great  problem that may make users confused as the edit form open the next row not the clicked row.

I want to expand all Master Table View Items from code behind (server side). To do this, I use Page_PreRenderComplete() event and expanding each MasterTableView Items.
It works fine, however for some reason the Paging Footer section is always visible. I want the Paging Footer to only appear if the number of records are bigger than the Page Size.
If you manually expand an item from UI, the Grid behaves correctly.
