PrintDialog(IWin32Window) Method

In This Topic

Invokes the standard Windows Print dialog box, which allows you to select additional options or settings and then to print the document currently displayed in the GdViewer control. This method uses the actual paper size when printing. At the same time, you can specify the top-level window that will own the modal dialog box using this method.

During the print process, the BeforePrintPage and the AfterPrintPage events are raised just before and right after the single page is printed.
