Why is my textBoxFor using my route data?

Question

So I have these three lines:

@Html.TextBoxFor(m => m.Id)

You could remove the problematic value from the ModelState (which is where the Html helpers are taking it from) in the controller action that is rendering the view:

public ActionResult SomeAction(int id)
{
    ModelState.Remove("Id");
    MyViewModel model = ...
    return View(model);
}

Now it's the Id property of your view model that's gonna get used by the TextBox and not the one coming from the route.

Obviously that's only an ugly horrible workaround. The correct way is to of course properly define your view models so that you do not have such naming collisions.
