control. The solution in microsoft's site is not working. It seems
that the handle event is never executed. here is my application...

<%@ Import Namespace="Microsoft.Web.UI.WebControls" %>
<%@ Register TagPrefix="tabs" Namespace="Microsoft.Web.UI.WebControls"
Assembly="Microsoft.Web.UI.WebControls" %>

<html>
<head>
<title>TabStrip without MultiPage</title>
</head>
<script language="C#" runat=server>
void Redirect_Click(Object sender, EventArgs E)
{
switch (tabs.SelectedIndex)
{
case 0:
Response.Redirect ("at_entr.aspx");
break;

case 1:
Response.Redirect ("at_quest.aspx");
break;

case 2:
Response.Redirect ("at_prob.aspx");
break;
}
}
</script>
<body style="font-family: verdana; font-size: x-small;">
<form runat="server">
<input type="hidden" id="objId" value="0" runat="server"/>
<tabs:TabStrip id="tabs" runat="server"
Style="font-weight:bold"
TabDefaultStyle="border:solid 1px
#003366;background:white;padding-left:1px;padding-right:1px;"
