PreviewPrintController.OnStartPrint(PrintDocument, PrintEventArgs) Method

Definition

Begins the control sequence that determines when and how to preview a print document.

public:
 override void OnStartPrint(System::Drawing::Printing::PrintDocument ^ document, System::Drawing::Printing::PrintEventArgs ^ e);
public override void OnStartPrint (System.Drawing.Printing.PrintDocument document, System.Drawing.Printing.PrintEventArgs e);
override this.OnStartPrint : System.Drawing.Printing.PrintDocument * System.Drawing.Printing.PrintEventArgs -> unit
Public Overrides Sub OnStartPrint (document As PrintDocument, e As PrintEventArgs)

Parameters

document
PrintDocument

A PrintDocument that represents the document being previewed.

e
PrintEventArgs

A PrintEventArgs that contains data about how to print the document.

Exceptions

The printer named in the PrinterName property does not exist.

Remarks

OnStartPrint is called immediately after PrintDocument raises the BeginPrint event.

OnStartPrint creates the Graphics that is displayed during the print preview. After OnStartPrint is called, the OnStartPage method sets the Graphics to a graphic of a single page. The OnEndPage method clears the Graphics, while the OnEndPrint method deallocates the object.

OnStartPrint verifies that the printer settings are valid.
