adding messagebox in ASP.NET
<p>How would I add a javascript MessageBox in ASP.NET in the code behind pages using C#.</p>

<p>I have something like this in mind although I still cant get it quite right.</p>

<pre><code>if (success == false)
    {
        HttpContext.Current.Response.Write("&lt;SCRIPT LANGUAGE=""JavaScript""&gt;alert('User name already exists')&lt;/SCRIPT&gt;");

    }
</code></pre>

<p>Kind regards</p>
