Are you using multipple threads?

This is likely some kind of threading issue. You can only interact with the grid on the thread that created it. In your code, you can do grid.InvokeRequired checks to see if you need to call grid.Invoke to make sure the call into the grid is being done on the proper thread. Here is a kb article on this. http://www.syncfusion.com/support/kb/grid/Default.aspx?ToDo=view&questId=78

You are right, it was fixed with

Private Delegate Sub SingleFunc()

_gridcontrol.Invoke(New SingleFunc(AddressOf _gridcontrol.EndUpdate))

Thank !
