DisplayFromGdPicturePDF Method (GdViewer)

In This Topic
Loads a PDF document from the instantiated GdPicturePDF object and subsequently displays it in the GdViewer control. The document previously displayed in the control will automatically close.

The BeforeDocumentChange and the AfterDocumentChange events are raised just before and right after the document is displayed in the GdViewer control. Both events are only raised if the document has been successfully loaded.
