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.
Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
Property ValueType: System::Boolean
true if partial rendering is enabled and full-page updates are suppressed; otherwise, false. The default is true.
Even if the 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 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.
