There are few things not clear to me about ASP.NET MV2.
In database I have table Contacts with several fields, and there is an additional field XmlFields of which type is xml. In that field are stored additional description fields.
There are 4 classes:
Contact
class which corresponds to Contact table and is defined by default when creating LINQ classes
ContactListView
class which inherits
Contact
class and has some
additional properties
ContactXmlView
class that contains
fields from XmlFields field
ContactDetailsView
class which
merges ContactListView and
ContactXmlView into one
class and
this one is used to display data in
view pages
ContactListView
class has re-defined some properties from Contact
class (so that I can add [Required] filter used for validation) - but I get warning message:
'ObjectTest.Models.Contacts.ContactListView.FirstName'
hides inherited member
'SA.Model.Contact.FirstName'. Use the
new keyword if hiding was intended.
ContactDetailsView
class is also used in a form when creating new contact and adding it to database.
I am not sure if this is correct way, and the warning message confuses me a bit. Any advise about this?
Thanks,
Ile
EDIT
According to Jakob's instructions I tried it from scratch:
[MetadataType(typeof(Person_Validation))]
public partial
class Person
{
}
public
class Person_Validation
{
[Required]
string FirstName { get; set; }
[Required]
string LastName { get; set; }
[Required]
int Age { get; set; }
}
In Controller I have this:
[HttpPost]
public ActionResult Create(Person person, FormCollection collection)
{
if (ModelState.IsValid)
{
try
{
personRepository.Add(person);
personRepository.Save();
}
catch
{
return View(person);
}
}
return RedirectToAction("Index");
}
View:
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Validate.Models.Person>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
Create
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<h2>Create</h2>
<% using (Html.BeginForm()) {%>
<%= Html.ValidationSummary(true) %>
<fieldset>
<legend>Fields</legend>
<div class="editor-label">
<%= Html.LabelFor(model => model.FirstName) %>
</div>
<div class="editor-field">
<%= Html.TextBoxFor(model => model.FirstName) %>
<%= Html.ValidationMessageFor(model => model.FirstName) %>
</div>
<div class="editor-label">
<%= Html.LabelFor(model => model.LastName) %>
</div>
<div class="editor-field">
<%= Html.TextBoxFor(model => model.LastName) %>
<%= Html.ValidationMessageFor(model => model.LastName) %>
</div>
<div class="editor-label">
<%= Html.LabelFor(model => model.Age) %>
</div>
<div class="editor-field">
<%= Html.TextBoxFor(model => model.Age) %>
<%= Html.ValidationMessageFor(model => model.Age) %>
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
<% } %>
<div>
<%= Html.ActionLink("Back to List", "Index") %>
</div>
</asp:Content>
When posting new person with no values, nothing happens (page is just reloaded). When posting with some values, person is added to db.
I have no idea what am I doing wrong.
