I'm currently implementing xVal client-side validation.
The server-side validation is working correctly at
the moment.
I have referenced xVall.dll (from xVal1.0.zip) in my project as well as
the System.ComponentModel.DataAnnotations and System.web.mvc.DataAnnotations from
the Data Annotations Model Binder Sample found at http://aspnet.codeplex.com/releases/view/24471. I have modified
the method BindProperty in
the DataAnnotationsModelBinder class since it returned a nullpointer exception telling me
the modelState object was null. Some blogposts described to modify
the method and I did according to this SO post.
Next I put
the following lines in my global.asax:
protected void Application_Start()
{
// kept same and added following line
RegisterModelBinders(ModelBinders.Binders); // Add this line
}
public void RegisterModelBinders(ModelBinderDictionary binders) // Add this whole method
{
binders.DefaultBinder = new Microsoft.Web.Mvc.DataAnnotations.DataAnnotationsModelBinder();
}
Now, I have made a partial class and a metadata class since I use
the entity framework and you cannot create partial declarations as of yet so I have:
[MetadataType(typeof(PersonMetaData))]
public partial class Persons {
// ....
}
public class PersonMetaData {
private const string EmailRegEx = @"^(([^<>()[\]\\.,;:\s@\""]+"
+ @"(\.[^<>()[\]\\.,;:\s@\""]+)*)|(\"".+\""))@"
+ @"((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}"
+ @"\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+"
+ @"[a-zA-Z]{2,}))$";
[Required]
public string FirstName { get; set; }
[Required]
public string LastName { get; set; }
[Required(ErrorMessage="Please fill in your email")]
[RegularExpression(EmailRegEx,ErrorMessage="Please supply a valid email address")]
public string Email { get; set; }
}
And in my controller I have
the POST edit method which currently still use a FormCollection instead of a Persons object as input. I have to change this later on but due to time constraints and some strange bug this isnt done as of yet :). It shouldnt matter though. Below it is my view.
//
// POST: /Jobs/Edit/5
//[CustomAuthorize(Roles = "admin,moderator")]
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Edit([Bind(Exclude = "Id")]FormCollection form) {
Persons
person = this.GetLoggedInPerson();
person.UpdatedAt = DateTime.Now; // Update
the updated time.
TryUpdateModel(person, null, null, new string[]{"Id"});
if (ModelState.IsValid) {
repository.SaveChanges();
return RedirectToAction("Index", "ControlPanel");
}
return View(person);
}
#endregion
My view contains a partial page containing
the form. In my edit.aspx I have
the following code:
<div class="content">
<% Html.RenderPartial("PersonForm", Model); %>
</div>
</div>
and in
the .ascx partial page:
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<WerkStageNu.Persons>" %>
<% if (!Model.AddressesReference.IsLoaded) { %>
<% Model.AddressesReference.Load(); %>
<% } %>
<%= Html.ValidationSummary("Edit was unsuccessful. Please correct
the errors and try again.") %>
<% using (Html.BeginForm()) {%>
<fieldset>
<legend>General information</legend>
<table>
<tr>
<td><label for="FirstName">FirstName:</label></td><td><%= Html.TextBox("FirstName", Model.FirstName)%><%= Html.ValidationMessage("FirstName", "*")%></td>
</tr>
<tr>
<td><label for="LastName">LastName:</label></td><td><%= Html.TextBox("LastName", Model.LastName)%><%= Html.ValidationMessage("LastName", "*")%></td>
</tr>
<tr>
<td><label for="Email">Email:</label></td><td><%= Html.TextBox("Email", Model.Email)%><%= Html.ValidationMessage("Email", "*")%></td>
</tr>
<tr>
<td><label for="Telephone">Telephone:</label></td><td> <%= Html.TextBox("Telephone", Model.Telephone) %><%= Html.ValidationMessage("Telephone", "*") %></td>
</tr>
<tr>
<td><label for="Fax">Fax:</label></td><td><%= Html.TextBox("Fax", Model.Fax) %><%= Html.ValidationMessage("Fax", "*") %></td>
</tr>
</table>
<%--<p>
<label for="GenderID"><%= Html.Encode(Resources.Forms.gender) %>:</label>
<%= Html.DropDownList("GenderID", Model.Genders)%>
</p> --%>
</fieldset>
<fieldset>
<legend><%= Html.Encode(Resources.Forms.addressinformation) %></legend>
<table>
<tr>
<td><label for="Addresses.City"><%= Html.Encode(Resources.Forms.city) %>:</label></td><td><%= Html.TextBox("Addresses.City", Model.Addresses.City)%></td>
</tr>
<tr>
<td><label for="Addresses.Street"><%= Html.Encode(Resources.Forms.street) %>:</label></td><td><%= Html.TextBox("Addresses.Street", Model.Addresses.Street)%></td>
</tr>
<tr>
<td><label for="Addresses.StreetNo"><%= Html.Encode(Resources.Forms.streetNumber) %>:</label></td><td><%= Html.TextBox("Addresses.StreetNo", Model.Addresses.StreetNo)%></td>
</tr>
<tr>
<td><label for="Addresses.Country"><%= Html.Encode(Resources.Forms.county) %>:</label></td><td><%= Html.TextBox("Addresses.Country", Model.Addresses.Country)%></td>
</tr>
</table>
</fieldset>
<p>
<input type="image" src="../../Content/images/save_btn.png" />
</p>
<%= Html.ClientSideValidation(typeof(WerkStageNu.Persons)) %>
<% } %
Still nothing really stunning over here. In combination with
the edited data annotation dlls this gives me server-side validation working (although i have to manually exclude
the "id" property as done in
the TryUpdateModel).
The strange thing is that it still generates
the following script in my View:
xVal.AttachValidator(null, {"Fields":[{"FieldName":"ID","FieldRules":
[{"RuleName":"DataType","RuleParameters":{"Type":"Integer"}}]}]}, {})
While all
the found blogposts on this ( 1, 2 ) but all of those are old posts and all say it should be fixed from xVal 0.8 and up.
The last thing I found was this post but I did not really understand. I referenced using Visual Studio - add reference -- browse - selected from my bin dir where I stored
the external compiled dlls (copied to
the bin dir of my project).
Can anyone tell me where
the problem originates from?
EDIT
Adding
the reference from
the .NET tab fixed
the problem somehow. While earlier adding from this tab resulted in a nullpointer error since it used
the standard DataAnnotations delivered with
the MVC1 framework instead of
the freshly build one. Is it because I dropped
the .dll in my bin dir that it now picks
the correct one? Or why?
