Required attribute in Data Annotations

Question

I'm using MVC 4 and Entity Framework 5 to build my website. To validate data in client side, I use Data Annotations. Here is my property in View Model:

public int Salary { get; set; }

As you can see, I don't put any annotation there. Also, in my database, the Salary column was marked as Allow null.

My problem is whenever I submit my form, the ModelState is invalid because of this property. It thinks that this property is required and display error on client side.

Do you know what causes the problem? Please help me. Thanks a lot.

The issue you are having is because the default constructor initializes the property to 0. If you want to allow nulls do this:public int? Salary { get; set; }
