This is a really strange behavior, and I've set up some demo code to try to figure out what's going on.
Basically have a a two actions and a single view. The first action sends an empty model to the view, the section action recieves the model, alters its contents and sends it back to the same view.
The wierdness is, in the view, the Model seems to have the updated values in it, but when I do an Html.TextBoxFor(x => x.PropertyNameHere) it renders a textbox with the unaltered value in it.
lol... I apologize in advance for the toilet humor, but it keeps the day from getting too boring. ;)
Does anyone have any idea what's going on here? Why is the output of TextBoxFor putting the old value in the value attribute?
Here's the code to replicate:
/Views/Demo/Index.aspx
<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<TestWeb.DemoModel>" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Demo</title>
</head>
<body>
<div>
<%using (Html.BeginForm("DemoSubmit", "Admin", FormMethod.Post)) { %>
Foo: <%=Html.TextBoxFor(x => x.Foo)%> <%:Model.Foo %><br />
Bar: <%=Html.TextBoxFor(x => x.Bar) %> <%:Model.Bar %><br />
PoopSmith: <%=Html.TextBoxFor(x => x.PoopSmith) %> <%:Model.PoopSmith %><br />
<button type="submit">Submit</button>
<%} %>
</div>
</body>
</html>
DemoModel.cs
namespace TestWeb {
public class DemoModel {
public string Foo { get; set; }
public int Bar { get; set; }
public string PoopSmith { get; set; }
}
}
DemoController.cs
public class AdminController : Controller {
public ActionResult Index() {
var m = new DemoModel();
return View(m);
}
public ActionResult DemoSubmit(DemoModel demo) {
demo.Foo += "!!!";
demo.Bar++;
demo.PoopSmith += " has pooped.";
return View("Index", demo);
}
}
And here's the bizarre output:
