TabContainer Issue

Dear All,

I have 4 tabs "A","B","C" and "D". Tab A is selected my default. When I go from tab "A" to any other tab the following event fires

protected void tabT_ActiveTabChanged(object sender, EventArgs e)
{
     Session["TabIndex"] = null;
     Session["TabIndex"] = tab.ActiveTabIndex;
     if (Request.QueryString["id"] == null)
    { 
        Response.Redirect("products.aspx?id=" + Session["pkid"]);
     }

}

which is working correctly.  But I want the same thing to happen when I click the default tab "A".  The problem is that the above ActiveTabChanged event does not  get fired when the default tab is clicked.  I want the above event to get fired when the default tab is also clicked.

Any help would be greatly appreciated.

cheers,

Sam
