Removing Required Attribute from Class but MVC3 still won't post the form without a value in the text box

Question

I have a class. At one point, I had set the properties of the class to [Required] using System.ComponentModel....

Okay, then I realized this was not needed. I have removed the required property but when I try to submit the form to an ActionResult the form does NOT post and still is trying to enforce the TextBoxFor(theModelProperty) to be populated.

I have deleted the "obj" folder, the "bin" folder, and also "Cleaned" the solutions. Still NO resolution.

I don't want to do a stupid workaround, I would like to do things correctly. Any idea why this occurs?

Answer 1

You have two options:

1. Set property as nullable,
2. Turn off required attribute for value types (see this answer)

Answer 2

If you have value type properties. Client validation will always generate required validations. If you don't want required validation for value types make them nullable.
