Pop-Window alert for wrong user nameand password

[quethzal]

I am using Visual Web Developer 2005 for implementing a web site that requires login. However I made the check for the valid user name and password and show login error in my default.aspx.cs file by the code segment

if (TextBox2.Text.Equals(dr["member_name"].ToString()))
      {
 if (DropDownList1.Text == "Customer")
         type = 1;
         }
        else
        {
        // Unauthorized
        Error.Visible = true;
        Error.Text = "Wrong username or password!";
        }
 

Error is a label created in default.aspx

But i need a pop up screen for alerting user for wrong logins. I search but couldnt find a proper way for throwing alerts by pop-up's in asp. By the way I wanna learn how can implement this pop-up window in aspx file by a script and how or in aspx.cs file which valid user check is made by a C# code.I am newbie
ın asp and thx for understanding and patience about my question...

Hi,

You can call a javascript function to Throw a popup alert.
<script language = "javascript">
function popup(url)
{
window.open(url);
}
</script>
