ScriptManager.EnablePartialRendering Property

Gets or sets a value that enables partial rendering of a page, which in turn enables you to update regions of the page individually by using UpdatePanel controls.

Namespace:  System.Web.UI
Assembly:  System.Web.Extensions (in System.Web.Extensions.dll)

Public Property EnablePartialRendering As Boolean
<asp:ScriptManager EnablePartialRendering="True|False" />

Property Value

Type: System.Boolean
true if partial rendering is enabled and full-page updates are suppressed; otherwise, false. The default is true.


The EnablePartialRendering property is set after the page's Init event occurs.

Even if the EnablePartialRendering property is true, partial-page rendering might not occur. The browser might not support partial-page rendering, or the SupportsPartialRendering property is set to false.

You can override the value of the EnablePartialRendering property at run time during or before the page's Init event. If you try to change this property after the page's Init event has occurred, an InvalidOperationException exception is thrown.
