ASP.NET MVC Model Binding

Model Binding with ASP.NET MVC works out-of-the-box with one exception: It does not handle null and string.Empty values incorrect. In those cases the model state is not updated, instead of setting the default value, or failing when those value do not represent a valid state.

This can be quite inconvenient, and the only way to overcome to provide a custom model binder.

Example Implementation

Basically, this implementation does not skip null and string.Empty values: TypeConverterModelBinder.cs

Registration

A custom model binder should be registered in the Global class:

public class Global
{
    protected override void Application_Start()
    {
        base.Application_Start();
        TypeConverterModelBinder.RegisterForAll(ModelBinders.Binders);
    }
}
