ReportViewer.AsyncRendering Property


Gets or sets a Boolean value that indicates whether the report is rendered asynchronously from the rest of the Web page when the Web page is being loaded.

Namespace:   Microsoft.Reporting.WebForms
Assembly:  Microsoft.ReportViewer.WebForms (in Microsoft.ReportViewer.WebForms.dll)

public bool AsyncRendering { get; set; }

Property Value

Type: System.Boolean

true if the report is rendered asynchronously; otherwise, false. The default is true.

After the report is rendered on page load, this property no longer determines the report rendering behavior. By default, all subsequent report renderings are accomplished with AJAX partial-page updates through asynchronous postbacks, and changing this property has no effect. For more information on partial-page updates and asynchronous postbacks, see Partial-Page Rendering Overview.

To control the asynchronous postback behavior, use the P:Microsoft.Reporting.WebForms.ReportViewer. InteractivityPostBackMode property.
