NEW QUESTION # 47
Refer to the exhibit

Users of this Visualforce page complain that the page does a full refresh every time the Search button Is pressed. What should the developer do to ensure that a partial refresh Is made so that only the section identified with opportunity List is re-drawn on the screen?

A. Ensure the action method search returns null.
B. Implement the <apex:actionfunction> tag with immediate = true.
C. Implement the render attribute on the <apex:ccxmandButton> tag.
D. Enclose the DATA table within the <apex:actionRegion> tag.

Answer: C

Explanation:
To ensure that only a part of the Visualforce page is refreshed, developers can use the reRender attribute of the <apex:commandButton> tag. This attribute specifies the IDs of the components that should be re-rendered as a result of the action method being completed. In this case, setting the reRender attribute to the ID of the <apex:pageBlockSection> that contains the opportunity list will cause only that section to be updated on the page, resulting in a partial page refresh.
The correct answer is B because it uses the reRender attribute correctly to update only the specific part of the page (opportunityList) without a full page refresh.
