I have a block of code that dynamicly adds HtmlInputFile controls to a user control that is then added to my aspx page. I want to have an onChange event that enables a submit button when a file box is changed. I have it working in Internet Explorer, but the same code does not work in Mozilla 1.3. Does anyone know if this onChange event should be working in Mozilla? I haven't been able to find anything about it not working for other people. I have also tried the onSelect event, but that didn't seem to work in either browser.
