DocumentPreviewWindow.PreviewControl Property

Provides access to the integrated document preview control.

Namespace: DevExpress.Xpf.Printing

Assembly: DevExpress.Xpf.Printing.v21.1.dll


public DocumentPreviewControl PreviewControl { get; }

Property Value

Type Description

A DocumentPreviewControl object that is integrated in the current window.


To create a custom DocumentPreviewWindow, assign the corresponding XtraReport or link to the DocumentViewerControl.DocumentSource property (available via the PreviewControl property).

using DevExpress.Xpf.Printing;
using System.Windows;
// ...

private void Button_Click(object sender, RoutedEventArgs e) {
    XtraReport1 report = new XtraReport1();
    var window = new DocumentPreviewWindow();
    window.PreviewControl.DocumentSource = report;

Call the XtraReport.CreateDocument method before you display the Print Preview. As an alternative, enable the PreviewControl.RequestDocumentCreation property before you specify the DocumentSource - so that Print Preview creates a document. Print Preview generates documents asynchronously in a separate task to allow other tasks to run concurrently. If you need Print Preview to create documents synchronously, disable the PreviewControl.UseAsyncDocumentCreation property.
