What is the issue with that ? If you have a control (say Button ) inside Update panel you can do redirection on that control click. As,
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Button ID="Button1" runat="server" Text="Button"
onclick="Button1_Click" />
</ContentTemplate>
</asp:UpdatePanel>
And on button click you can do the redirection.
protected void Button1_Click(object sender, EventArgs e)
{
Response.Redirect("http://google.com");
}
Or you are looking for something else.
