I have a cell bound to a XamComboEditor, it works fine, but having the cell selected(and not in edit mode) and hitting delete causes the ClearCellContents command to fire. This sets the value to null and seems to bypass the nullable=false validation that i have set for the editor. How can I prevent the user from being able to clear the value of a XamComboEditor?
You can handle the ExecutingCommand event and see if the command is ClearCellContents and cancel it.
