Invokes the Print Preview Form which modally shows the print preview of the document for this link.
Namespace: DevExpress.XtraPrintingLinks
Assembly: DevExpress.XtraPrinting.v23.2.dll
NuGet Packages: DevExpress.Win.Navigation, DevExpress.Win.Printing
Declaration
Remarks
Use the ShowPreviewDialog method to invoke the PrintPreviewFormEx form and show the print preview of the document created for this link. Note that if the link’s document hasn’t been created (the TreeViewLink.CreateDocument method hasn’t been called for it), then calling the ShowPreviewDialog method will create it first.
Consequently, if a document was created prior to calling the ShowPreviewDialog method, and nothing was changed that may force its re-creation, the ShowPreviewDialog method doesn’t re-create it, so you need to manually call the TreeViewLink.CreateDocument method, if required.
