I have a view with a dropdown and a Rich Textbox. This view is associated with a model. I would like to make Rich Textbox field is required based on the value selected in dropdownlist.
is there any out of the box feature available in MVC3 to do this?
I have had similar requirements in the past, I solved them using FoolProof. It provides extra validation objects such as requiredIf etc.
Only issue I have had is with the JS file, it can be a bit buggy around dates and date handling, other than that, it is ace.
