TabContainer要实现服务器端回传

TabContainer要实现服务器端回传,出来在后台实现 OnActiveTabChanged 事件外,
还需要在前台实现 OnClientActiveTabChanged 事件，这是关键。

< asp:UpdatePanel  ID ="UpdatePanel1"  runat ="server"  ChildrenAsTriggers ="true" >
     < contenttemplate >
         < ajaxToolkit:TabContainer  runat ="server"  ID ="Tabs"  Height ="480px"  Width ="100%"  
            OnClientActiveTabChanged ="activeTabChanged"
            OnActiveTabChanged ="Tabs_ActiveTabChanged" >
             < ajaxToolkit:TabPanel  runat ="Server"  ID ="Panel1"  HeaderText ="我的消息" >
                 < ContentTemplate >
                ***
                 </ ContentTemplate >
             </ ajaxToolkit:TabPanel >
             < ajaxToolkit:TabPanel  runat ="Server"  ID ="Panel2"  HeaderText ="已发消息" >
                 < ContentTemplate >
                    ***
                 </ ContentTemplate >
             </ ajaxToolkit:TabPanel >
         </ ajaxToolkit:TabContainer >
     </ contenttemplate >
     < triggers >
         < asp:AsyncPostBackTrigger  ControlID ="Tabs"  EventName ="ActiveTabChanged"   />
     </ triggers >
</ asp:UpdatePanel >

< script  language ="javascript"  type ="text/jscript" >
function activeTabChanged(sender, e) 
{ 
    __doPostBack('<%= Tabs.ClientID %>', sender.get_activeTabIndex()); 
}
</ script >

后台.cs代码:

protected   void  Tabs_ActiveTabChanged( object  sender, EventArgs e)
{
    switch (Tabs.ActiveTabIndex)
    {
        case 0:
            BindGrid();
            break;
        case 1:
            BindGrid2();
            break;
        case 2:
            Message.Text = "";
            break;
        default:
            break;
    }
}
