A method that handles the SpreadsheetControl.VisibleRangeChanged event.
The event source. This parameter identifies the SpreadsheetControl that raised the event.
An object that contains event data.
When creating a VisibleRangeChangedEventHandler delegate, you identify the method that will handle the corresponding event. To associate the event with your event handler, add a delegate instance to this event. The event handler is called whenever the event occurs unless you remove the delegate. For more information about event handler delegates, see Events and Delegates in MSDN.
