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

Use ModelState.Clear() before setting value

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