I'm using ASP.NET MVC and Microsoft AJAX to create an AJAX form using this following syntax: using (Ajax.BeginForm()) { ... } This works fine if the user clicks a submit button.

Now, if you're only using Brushes.Black, then it's probably ok to not dispose it, because you're only leaving one unmanaged resource (hopefully!) ...
