在刷新和提交页面后，保存滚动条的位置

在PageLoad中调用下面的方法Position，注意StringBuilder属于System.Text命名空间

private void Position()
{

       RegisterHiddenField("ScrollPostion", "0");
       StringBuilder getPosition = new StringBuilder();
       getPosition.Append("<script language=javascript>");       
       getPosition.Append("function get(){");       
       getPosition.Append("document.forms[0].__SCROLLPOS.value = thebody.scrollTop;");
       getPosition.Append("}");       
       getPosition.Append("thebody.onscroll=saveScrollPosition;");      
       getPosition.Append("</script>");
       ClientScript.RegisterStartupScript(typeof(Page),"savePosition",getPosition.ToString());
if (IsPostBack)
       {
                StringBuilder setPosition = new StringBuilder();
                setPosition.Append("＜script language='javascript'＞");
                setPosition.Append("function setScrollPosition() {");
                setPosition.Append(" thebody.scrollTop = " + Request["ScrollPostion"] + ";");
                setPosition.Append("}");
                setPosition.Append("thebody.onload=setScrollPosition;");
                setPosition.Append("＜/script＞");
                RegisterStartupScript("setScroll", setPosition.ToString());
        }
}
