Hi! I have some problems. Initial conditions: 1) grid with datasource, 2) one of columns has dropdown list. This is the only column that I need to interact. When I try to delete one of the rows, I'd like to cancel deletion event. I subscribe to BeforeRowsDeleted event and set e.Cancel = true in the event handler Result: 1) I can't select row (it doesn't change color as it should be for Active or Selected row) 2) Dropdown list doesn't show up (unfold/drop down) What can cause such behaviour? I appreciate your help much.
