Question

I am using MVC-View Model, EF Model first

I am having problems with two of my Properties inside my View Model which is following:

[Required]
public string TeamName { get; set; }
[Required]
public string ConsultantName { get; set; }

These two properties can get disabled depending on what SubjectTypeName the user choose

 [Required]
 public string SubjectTypeName { get; set; }

Lets say I choose a SubjectTypeName Value and my TeamName and ConsultantName gets disabled, but when I want to save the form I get error beacuse my ModelState.IsValid gets false. And its the [Required] that makes it "false".

Is there any easy solutions for this? Like a easy Jquery code to inactive TeamName and ConsultantName from the validation so my ModelState.IsValid becomes "true"?

Thanks in Advance!

You may take a look at the following blog post which illustrates how you could write a custom [RequiredIf] validation attribute that will handle conditional validation on the server and on the client. You can directly download the Mvc.ValidationToolkit which contains this validation attribute.
