Use this:

protected void ddlAuthoritytype_SelectedIndexChanged(object sender, EventArgs e)
{
    var port = Request.Url.IsDefaultPort ? "" : ":" + Request.Url.Port.ToString();

    string ddl = ddlAuthoritytype.SelectedValue;
    switch (ddl)
    {
        case "AL":
            var script = string.Format("window.open('{0}://{1}{2}{3}')", Request.Url.Scheme, Request.Url.Host, port, ResolveUrl("~/alabama-state-tax-calculator.aspx"));
            ScriptManager.RegisterStartupScript(this, this.GetType(), "newWindow",script, true);
            break;
    }
}

you should use the following script:

<script type="text/JavaScript">
<!--

function openWindowFromDropDownList(theURL,winName,features)

{ 

var SID = document.forms[0].dropdownlist1.value
if (SID > 0){
theURL = theURL + document.forms[0].dropdownlist1.value
    var newWin = window.open(theURL,winName,features);
    newWin.opener = self;
  }
}
//-->
</script>

So you want a postback and process the change on the server right? Does ddlAuthoritytype have its autopostback property set?

Have you tried doing a Response.Redirect in the switch instead of injecting script?

Edit: Ah, missed the new tab part, now I see why the script.
