PrintControl.UseAsyncDocumentCreation Property

Gets or sets whether the DocumentViewer should create a report document asynchronously in a separate task.

Namespace: DevExpress.XtraPrinting.Control

Assembly: DevExpress.XtraPrinting.v20.1.dll

Declaration

[DefaultValue(DefaultBoolean.Default)]
public DefaultBoolean UseAsyncDocumentCreation { get; set; }
<DefaultValue(DefaultBoolean.Default)>
Public Property UseAsyncDocumentCreation As DefaultBoolean

Property Value

Type Default Description
DefaultBoolean

Default

True or Default, to create a report document asynchronously in a separate task; otherwise, False.

Remarks

Set this property before you assign an XtraReport class instance to the DocumentViewer. Asynchronous document creation does not lock other actions performed in the application. For instance, the user interface remains responsive.

Example

The code sample below creates a DocumentViewer instance, specifies that this instance should create documents asynchronously, and assigns an XtraReport to this instance for preview.

using System;
using System.Windows.Forms;
using System.Threading;
using DevExpress.Utils;
using DevExpress.XtraReports.UI;
using DevExpress.XtraPrinting.Preview;
// ...
DocumentViewer viewer = new DocumentViewer();
viewer.UseAsyncDocumentCreation = DefaultBoolean.True;
viewer.DocumentSource = report;
