Question

I developed a editor template wich take boolean types and creates a dropdownlist, to changed the true and false default values, into Si and No. Now when I deployed the application i didn’t realized that the boolean and Nullable<boolean> are taken like the same and affected for the name of my editor template (boolean.cshtml). Now I don’t want this, I want to modify the behavior of the editorfor, only when the datatype of the model was Nullable<boolean> not when it’s boolean. How can I handle this???

 @model Nullable<bool>

@{
    var listItems = new[]
    {
        new SelectListItem { Value = "true", Text = "Si" },
        new SelectListItem { Value = "false", Text = "No" }
    };  

}


@Html.DropDownListFor( model => model.Value, listItems)

You can’t prevent them using the same editor template. But you can handle it within the editor template. You have:

ViewData.ModelMetadata.IsNullableValueType

If you read this article, you can actually see what the default template does with this to switch between two different renderings. Just steal from it:
