下面来看一个示例：
1)在VS2005中新建一个ASP.NET AJAX-Enabled Web Project项目工程，命名为Tabs。
2)在Default.aspx页面上添加一个TabContainer控件，同时在该容器控件中添加两个TabPanel。分别命名为TabPanel1和TabPanel2，同时设置HeaderText为QQ和Msn,电影,音乐。
<cc1:tabcontainer id="TabContainer1" runat="server" activetabindex="0" OnClientActiveTabChanged="ActiveTabChanged" OnActiveTabChanged="TabContainer1_ActiveTabChanged"><cc1:TabPanel runat="server" HeaderText="TabPanel1" ID="TabPanel1"><ContentTemplate> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate>QQ:<asp:TextBox id="TextBox1" runat="server"></asp:TextBox> <br /> pwd<asp:TextBox id="TextBox2" runat="server"></asp:TextBox><br /> <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" /> <asp:Label ID="Label1" runat="server" Text="Label" Width="153px"></asp:Label><br /> <asp:Label ID="Label2" runat="server" Text="Label" Width="189px"></asp:Label> </ContentTemplate> </asp:UpdatePanel> <BR /></ContentTemplate><HeaderTemplate>QQ</HeaderTemplate></cc1:TabPanel><cc1:TabPanel runat="server" HeaderText="TabPanel2" ID="TabPanel2"><ContentTemplate>msn:<asp:TextBox id="TextBox3" runat="server"></asp:TextBox> <BR />pwd<asp:TextBox id="TextBox4" runat="server"></asp:TextBox> </ContentTemplate><HeaderTemplate>MSN</HeaderTemplate></cc1:TabPanel><cc1:TabPanel runat="server" HeaderText="TabPanel3" ID="TabPanel3"><ContentTemplate>你最喜欢什么电影</ContentTemplate><HeaderTemplate>电影</HeaderTemplate></cc1:TabPanel><cc1:TabPanel runat="server" HeaderText="TabPanel4" ID="TabPanel4"><ContentTemplate>你最喜欢什么音乐</ContentTemplate><HeaderTemplate>音乐</HeaderTemplate></cc1:TabPanel></cc1:tabcontainer><br />属性说明：
OnClientActiveTabChanged：在客户端对当前激活的Tab进行改变时执行的事件脚本。
HeaderText：在TabContainer中的每个Tab的标题内容。
function ActiveTabChanged(sender, e) 
{
var CurrentTab = $get('<%=lblMsg.ClientID%>');//lblmsg这个是lable的控件id,lable在ie状态下就是<span>的形式表现的. lblMsg.innerHTML = sender.get_activeTab().get_headerText();30在页面上添加ActiveTabChanged事件函数，用于显示。
这个函数是写在aspx页面的,用于绑定 OnClientActiveTabChanged
4)在TabContainer下面拖放一个Label，命名为lblMsg。用于显示当前激活的Tab。
代码如下:
<asp:Label ID="lblMsg" runat="server" Text="Label"></asp:Label>效果如下:
整体代码如下:
