An exception is any error condition or unexpected behavior encountered by an executing program. Whenever an error occurs, an Exception object is created and thrown to represent the exception.
The exceptions that can be thrown by Xceed Grid for WinForms, are handled in the same manner as regular run-time exceptions by using Try/Catch blocks. Whenever you contact technical support regarding an exception, please include the ToString () result of the exception.
