SetFocus()用来将光标聚焦到某个页面控件上
<%@ page language="C#" %><script runat="server"> void Page_Init(object sender, EventArgs e)
{
SetFocus(focusHere);
}</script><html><head id="Head1" runat="server"> <title>Untitled Page</title></head><body> <form id="form1" runat="server"> <asp:textbox id="default" runat="server" /><br /> <asp:textbox id="focusHere" runat="server" /> </form></body></html>MaintainScrollPositionOnPostback 设置成true可以在页面PostBack的时候保持页面滚动条的位置
在web.config作如下设置即可：
<pages smartNavigation="true" maintainScrollPositionOnPostBack="true"/>
