custom validator for last day of a month - c#
<p>I'm new to asp.net, so plz bear with me: I want to create a custom validator to check if the input date given in a textbox (which has a calendar extension(AJAX)) is the last day of a month or not. Here is what I tried to do:</p>

<pre><code>protected void CustomValidator1_ServerValidate(object source, ServerValidateEventArgs e)
{

    DateTime dt = Convert.ToDateTime(e.ToString("dd/MMM/yyyy"));
    DateTime lastOfMonth = new DateTime(dt.Year, dt.Month, 1).AddMonths(1).AddDays(-1);
    if (dt == lastOfMonth)
    {
        e.IsValid = true;
    }
    else
    {
        e.IsValid = false;
    }

}
</code></pre>

<p>I think the problem is the way I'm handling the object 'e'. Any help is greatly appeciated. Thanks a lot in advance!</p>
