UpdatePanel control

Question

Explain about the UpdatePanel control.

Answer 1

UpdatePanel control states the portion of the Web page which is updated altogether. As UpdatePanel control refreshes only the selected part of Web page in place of refreshing entire page with a postback, more flexibility is achieved for creating rich and client-centric Web applications.
This process of refreshing the selected part of a Web page is referred to as the partial-page update. One or more UpdatePanel control can be added in the Web page that automatically participates in the partial-page update without custom client script. UpdatePanel control uses the UpdatePanel class in order to support the partial-page rendering.
