A method that handles the SpreadsheetControl.ColumnWidthChanged event.
The event source. This parameter identifies the SpreadsheetControl that raised the event.
An object that contains event data.
When you create a ColumnWidthChangedEventHandler delegate, you identify the method that handles the SpreadsheetControl.ColumnWidthChanged event. Add a delegate instance to the event to associate the event with your event handler. The event handler is called whenever the event occurs, unless you remove the delegate. See Handling and Raising Events for more information about event-handler delegates.
