Document. On Begin Print(PrintEventArgs) Method
protected: virtual void OnBeginPrint(System::Drawing::Printing::PrintEventArgs ^ e);
protected virtual void OnBeginPrint (System.Drawing.Printing.PrintEventArgs e);
abstract member OnBeginPrint : System.Drawing.Printing.PrintEventArgs -> unit override this.OnBeginPrint : System.Drawing.Printing.PrintEventArgs -> unit
Protected Overridable Sub OnBeginPrint (e As PrintEventArgs)
The OnBeginPrint method allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors
When overriding OnBeginPrint(PrintEventArgs) in a derived class, be sure to call the base class's OnBeginPrint(PrintEventArgs) method so that registered delegates receive the event. This method is a good place for initialization.
