Printing Support

RadDiagram provides options to print its content by using a RadPrintDocument.

RadDiagram Print Support

RadDiagram has two public methods available for printing - Print() and PrintPreview(). The first method will directly send a print job to the default printer with the settings currently saved in the PrintStyle property. This method has one overload available which can show a system PrintDialog with the available printers and their options.

this.radDiagram1.Print();
this.radDiagram1.Print(true);

Me.RadDiagram1.Print()
Me.RadDiagram1.Print(True)

The other available method is PrintPreview(), which opens RadPrintPreviewDialog.

this.radDiagram1.PrintPreview();

Me.RadDiagram1.PrintPreview()

In order to modify it, you can change some or all of the following properties:

• LineStroke - this property is of type Brush and it specifies how the PagesPreview canvas outline is painted.

• LineStrokeDashArray - this property gets or sets a collection of Double values that indicate the pattern of dashes and gaps that is used to outline the DiagramElement.BackgroundPageGrid.

• LineStrokeThickness - this property is of type double and it gets or sets the thickness of the DiagramElement.BackgroundPageGrid.

• PageSize - controls the size of the DiagramElement.BackgroundPageGrid.

By default, the PageSize property is set to Size(1092, 763) . Note that the default printer may have different page size applied.

If you place shapes on different pages, these pages will be printed as well:
