Overload	Description
DisplayFromFile(String)	Loads a document from a file according to a file path you have specified and subsequently displays it in the GdViewer control. The document previously displayed in the control will automatically close. All document formats currently supported by the toolkit are listed here. 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. Be aware that the required file is locked for another use by default when loading.
