TextBoxFor value not updating after post

Question

I have a simple strongly typed view, but I cant seem to update a textbox on my form after a post.

Here is my model:

public class Repair
  {
    public          


        

Answer 1

If you find ModelState.Clear() to be too destructive, you can target only the item you are changing, while preserving the rest with ModelState.Remove()

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Index(Repair r)
{
    r.Number = "New Value";
    ModelState.Remove("Number");
    return View(r);
}

Also, it appears that it doesn't matter with either Remove() or Clear() whether you call that method before you update your model or after
