I have this classes:
public class GroupMetadata
{
[HiddenInput(DisplayValue = false)]
public int Id { get; set; }
[Required]
public string Name { get; set; }
}
[MetadataType(typeof(GrupoMetadata))]
public partial class Group
{
public virtual int Id { get; set; }
public virtual string Name { get; set; }
}
And this action:
[HttpPost]
public ActionResult Edit(Group group)
{
if (ModelState.IsValid)
{
// Logic to save
return RedirectToAction("Index");
}
return View(group);
}
That's my view:
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.
Web.Mvc.ViewPage<Group>" %>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<% using (Html.BeginForm()) {%>
<fieldset>
<%= Html.EditorForModel() %>
<p>
<input type="submit" value="Save" />
</p>
</fieldset>
<% } %>
<div>
<%=Html.ActionLink("Back", "Index") %>
</div>
</asp:Content>
But ModelState is always invalid! As I can see, for MVC validation 0 is invalid, but for me is valid.
How can I fix it since, I didn't put any kind of validation in Id property?
UPDATE:
I don't know how or why, but renaming Id, in my case to PK, solves this problem.
Do you know if this an issue in my logic/configuration or is an bug or expected behavior?
Thank you
