The UpdatePanel and UpdateProgress Controls

Introduction

Partial-page rendering makes it unnecessary for the whole ASP.NET page to be refreshed as the result of a postback. Instead, only the region of the page that has to be refreshed is updated. As a result, users do not see the whole page reload with every postback, which makes user interaction with the Web page more seamless.
