Which of the following properties of the UpdatePanel control is used to set a value that indicates
whether postbacks from immediate child controls of the UpdatePanel control update the panel’s
content?

A.
ContentTemplate

B.
EnablePartialRendering

C.
IsInPartialRendering

D.
ChildrenAsTriggers

Explanation:
The ChildrenAsTriggers property is used to set a value that indicates whether postbacks from
immediate child controls of an UpdatePanel control update the panel’s content. This property is set
to true if a user wants postbacks from immediate child controls of the UpdatePanel control to cause
an update of the panel’s content.
Answer A is incorrect. This property gets or sets the template that defines the content of the
UpdatePanel control.
Answer B is incorrect. The EnablePartialRendering property of the ScriptManager control is used to
determine whether a page participates in partial-page updates. The default value of this property is
true. When a user adds a ScriptManager control to the page, by default partial-page rendering is
enabled. This property enables partial rendering of a page, which in turn enables a user to update
regions of the page individually by using UpdatePanel controls.
Answer C is incorrect. This property gets a value that indicates whether the UpdatePanel control is
being updated as a result of an asynchronous postback.
