What you can do is conditionally register some javascript for opening the Popup when the button is clicked.

Lets say you define your popup like this:

<ajax:PopupControlExtender ID="popup" runat="server"
    TargetControlID="textbox"
    BehaviorID="mybehavior"
    PopupControlID="panel"
    Position="Bottom" />

Then, on the button click event:

if(Session["id"] == null)
{
    var script = @"Sys.Application.add_load(function() { $find('mybehavior').showPopup(); });";   
    ScriptManager.RegisterStartupScript(this, GetType(), "ShowPopup", script, true);
}
else
{
     //Redirect;
}
