Gets or sets whether the DocumentViewer should create a report document asynchronously in a separate task.
Namespace: DevExpress.XtraPrinting.Control
Assembly: DevExpress.XtraPrinting.v21.1.dll
NuGet Packages: DevExpress.Win.Design, DevExpress.Win.Printing
Declaration
[DefaultValue(DefaultBoolean.Default)]
public DefaultBoolean UseAsyncDocumentCreation { get; set; }Property Value
| Type | Default | Description |
|---|---|---|
| DefaultBoolean | **Default** | True, to create a report document asynchronously in a separate task; otherwise, False. Default specifies the same behavior as False. |
Available values:
| Name | Description |
|---|---|
| True | Corresponds to a Boolean value of true. |
| False | Corresponds to a Boolean value of false. |
| Default | The default behavior determined by the control’s logic. |
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;
