ASP.NET MVC optional field being treated as required

Question

I have this field that for some reason when I click on submit, gets a validation message that the field is required.

[DisplayName(\"Total Budget:\")]
public          


        

Answer 1

You have to add the following line in the application_start (global.asax)

DataAnnotationsModelValidatorProvider.AddImplicitRequiredAttributeForValueTypes = false;

Source: Unrequired property keeps getting data-val-required attribute
