A method that will handle the DocumentPropertiesChanged event of the SpreadsheetControl.
The event source. This parameter identifies the SpreadsheetControl which raised the event.
A DocumentPropertiesChangedEventArgs object which contains event data.
When creating a DocumentPropertiesChangedEventHandler delegate, you identify the method that will handle the corresponding event. To associate an 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.
