Title Body

I've been playing with ASP.NET MVC and ran into something I can't figure out. Suppose I have an object like this : public class TestObject { public string Name { get; set; } public int Age { get; set; } } And a view page (Create.aspx) like this : <form action="/Create" method="post"> <p> <%=Html.TextBox("Name") %> </p> <p> <%=Html.TextBox("Age")%> </p> </form> And on my controller I have these actions : [AcceptVerbs(HttpVerbs.Get)] public ActionResult Create() { return View(new TestObject { Name = "DefaultName", Age = 10 } ); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create(TestObject o) { o.Name = "ChangedNameToSomethingElse"; o.Age = 15; return View(o); } The Html.TextBox() method always genereates the textboxes with the default values, even after the postback, where the object is passed back with different properties on its values. Now, granted, I can't think of a real world example why I'd want to do such a thing but I still don't understand why I always end up having textboxes populated with the model's values that were set on the Create action with the AcceptVerbs(HttpVerbs.Get) attribute. Note : I've tried Html.TextBox("Name", Model.Name) but the result is still the same. And I verified that the Create action with AcceptVerbs(HttpVerbs.Post) actually runs, by passing a value via ViewData to the View. Also, the udated value is displayed when I output the value with <%=Model.Name %> but again, not on the textbox. Is there something obvious I'm missing, or is there a reasoning behind this behaviour?
