I have a RadGridView that is working nicely, but I'm having trouble with the Expression Column:
1) I let the Expression Cloumn show via right mouse click. It shows and is empty
2) I click on the header of the expression column
3) the GridView wnats to sort the empty Expression column and crashes
How do I prevent this? GridView should be stable out of the box, no matter what the user clicks.

Sorry Dimitrina,
that I posted this twice, but your forums seem to have problems with Opera browsers. Several times I tried to post a forum question and them comes the answer from your web server: "Uups sorry, problem" (or something like this) and then I had to post again.
Maybe you should tell this your web guys...
