I am attempting to implement a number of RadDatePickers throughout an application. I am stuck, though, on performing validation the way I want it to work. The desired behavior would be to have a Validator attached to the DatePicker that prevents the page from posting back if the text in the DateInput is not a valid date, but does allow a post if the DateInput is empty. None of the standard ASP.NET validators seem to do the job because the DateInput appears empty to them whenever it has an invalid text. This behavior would be necessary on a number of different pages throughout the application, so individually handling each DatePicker with a CustomValidator would not be a desirable solution. Is there some solution that would work using the available validation tools, or would implementing a new validator type be the best way to accomplish this?

Hello Jeremy,

Try the solution provided in this code library and see if it works for you.

I hope this helps.

While this is what I was trying to do, the CustomValidator solution linked isn't ideal for application-wide deployment. At this point I've already written my own validation control to handle the situation.
