Do you get any exception? If not, it is possible there is one, but you don’t see because it is swallowed by the grid or the framework.
Is the debugger set to break on all exceptions? (Debug Menu -> Exceptions -> Common Language Runtime Exception, then select “Break into the debugger” radio button). This will make sure that no exceptions are swallowed by the grid or the framework, and that the debugger will break in any part of the code.
