ListBox in Edit form

[Joff]

Hi,
I have a RadGrid with some columns like edit, delete, other autogenerated columns. I want to add a listbox in editform dynamiclly.
Now I create dynamically a templatecolumn in radgrid that is not visible, then when I click to edit I see my ListBox and the other fields but there is a problem because if I click "Update" or "Cancel" the edit crash and you do not ecape from edit form pop-up.
Another problem is that when I go to edit form, the listbox column appear in the radgrid.

Thanks

joff

What you're trying to do is pretty standard functionality
please add code and a .jpg of the error you are getting ("form crashes" is not very specific)
