Public Property AsyncRendering As Boolean
Dim instance As ReportViewer
Dim value As Boolean

value = instance.AsyncRendering

instance.AsyncRendering = value
public bool AsyncRendering { get; set; }
property bool AsyncRendering {
    bool get ();
    void set (bool value);
/** @property */
public boolean get_AsyncRendering ()

/** @property */

public function get AsyncRendering () : boolean

public function set AsyncRendering (value : boolean)

Property Value

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 InteractivityPostBackMode property.
