ASP.NET MVC Razor Unrequired property keeps getting data-val-required attribute

If you have the problem that your text field validation gets generated althoug there is no Required attribute set on property, use the next code in the Application_Start to force the compiler to validate only if there is a required attribute on the property:

// Whit this line of code you will remove data-val-required DataAnnotationsModelValidatorProvider.AddImplicitRequiredAttributeForValueTypes = false;

// With these two lines you will remove data-val-number and data-val ModelValidatorProviders.Providers.Clear();
ModelValidatorProviders.Providers.Add(new DataAnnotationsModelValidatorProvider());

ASP.NET MVC Razor Override "id" and “name” attribute with TextBoxFor

Use the code below as example to override the id or/and name attributes with TextBoFor, something really important to keep in mind is that "id" and "Name" is case sensitive.

    
   @Html.TextBoxFor(x => x.Data, new { Name = Model.Name + "_Custom", id = Model.ID + "_Custom" })
