Actually only ie 7 has this issue. ie 8 can validate hidden fields even without your added code.

@Kon: Glad you found the article useful. I had thought about doing it that way, but that didn’t feel right since it meant changing their implementation for _isTextualInputElement(), which could cause problems if they change that function otherwise in future versions. It doesn’t seem worth it to change their implementation when they already provide the means to add your own custom behavior.

On top of that, I also figured this provided a good example of how to add custom validation in general

Hi, thanks for your article – I was looking for just this. However, once I got to the end and started to think about where it’s more appropriate to place the actual validation function, I started spilunking through the MicrosoftMvcValidation.js and realized that none of this is really necessary. I believe, all you have to do is alter the Sys.Mvc.RequiredValidator._isTextualInputElement() function and add the “HIDDEN” inputType case. Wouldn’t this be enough and easier/simpler than creating new attributes and so on?
