Temp asked on 20 Jun 2008, 07:15 AM
I have a very simple scenario here, with a Tab strip with two tabs, that changes the datasource of a grid (so it would load different categories of products for example). I am trying to get this to work, and it seems to go well until I click edit to edit a row, because then the whole grid disappears.

Can someone please help me with this. It is very simple I am sure.Where am I going wrong?
