            ContentPanel1.Visible = false;
            ContentPanel2.Visible = false;
            ContentPanel3.Visible = true;

问题解决了设置 PageManager EnableAjax="false" 后ContentPanel.Visible才起作用
DropDownList SelectedIndexChanged 后才刷新页面
<ext

ageManager ID="

ageManager1" EnableAjax="false" AjaxAspnetControls="Label1,Literal1,Literal2_Container"
runat="server" />

这样做可以得到隐藏和显示的效果，但有闪烁，不知三石老大有没有别的方法？
