UpdatePanel控制并移至页面顶部

I have an asp.net page that is using an UpdatePanel control. When you're on the page and you click the continue button, the page does a partial refresh and you're left in the same scroll position you were before the refresh. How do I ensure that on partial refreshes with the UpdatePanel control that you return to the top of the page.I have an asp.net page that is using an UpdateP
