DiagramView.PrintPreviewEx Method (Form)

Displays a custom preview form.

Namespace: MindFusion.Diagramming.WinForms
Assembly: MindFusion.Diagramming.WinForms

 Syntax

C#

public void PrintPreviewEx (
    Form previewForm
)

Visual Basic

Public Sub PrintPreviewEx( _
    previewForm As Form _
)

 Parameters

previewForm

A custom preview form to display instead of the standard .NET print preview dialog.

 Remarks

Opens an extended Print Preview window for the current diagram. Compared to the standard .NET preview dialog, the extended one provides better-looking icons and additional buttons such as "page orientation" and "scale to page". PreviewOptions allows assigning custom images to the preview toolbar buttons and localizing the menu item and tooltip texts.

The preview output is rendered with the same settings that are used for printing, assigned by the PrintOptions structure. That ensures uniform output of the printed document both on paper and in the preview mode. Print job settings include document title and several flags that control whether images, shadows, headers, and so on, are printed.

It is possible to create your own preview form and specify it as an argument. Your preview form class must implement the IPrintPreview interface defined in MindFusion.Diagramming.WinForms.dll. IPrintPreview contains a single property called Document of type System.Drawing.Printing.
