My problem is that whenever a user selects a file that exceeds a certain amoutn of Mb (about 8) I get a page error that says the following:
I would really like use the jQuery Validation plugin in my ASP.NET Web Forms application (not MVC). I find it easier than adding asp validators everywhere and setting the control to validate field on all of them.
