MVC :: DataAnnotation Validation Order?
Aug 11, 2010
PropertiesMustMatch fails because for some reason it's hit PRIOR to "Required" property. How come??
how do you set the order or validation so that Required is hit prior to any custom validation?
I have a class like so:
[Validation.PropertiesMustMatch("Password", "ConfirmPassword", ErrorMessage = "'Password' and 'Confirm password' do not match.")]
[Validation.ValidateMemberUsername("Username", "Oldusername")]
public class Member
[code]....

I've got a view with 2 forms on it - one to login and the other to register. My problem is that the client-side validation from MicrosoftMvcValidation is firing regardless of which form I submit - because my forms are rendering the inputs with the same id e.g.
<input id="User_Email"
name="User.Email" type="text"
value="" />
How can I change the generated forms to create different id's for the inputs in such a way that the validation works?
I'm using a strongly-typed view with a model with this property:
Model property:
[Required(ErrorMessage = "Please enter an email address")]
public string Email { get; set; }
First form:
<% using (Html.BeginForm("LogOn", "Account")) { %>
<%= Html.ValidationMessageFor(m => m.User.Email) %>
<%= Html.TextBoxFor(m => m.User.Email) %><% } %>
Second form:
<% using (Html.BeginForm("Register", "Account")) { %>
<%= Html.ValidationMessageFor(m => m.User.Email) %>
<%= Html.TextBoxFor(m => m.User.Email) %><% } %>
My second form produces id's identical to the first form which is causing the problem.
Is it possible to specify the difference in the Html helper on the view or do I need to provide 2 seperate models somehow? I'm a bit in the dark.

With my model, I have one view model using another as its base. In my case, BaseUserModel is inherited by CreateUserModel, in order to share common properties such as Username and Password. My CreateUserModel adds to that by having ConfirmPassword, Email, SecurityQuestion, etc.
My problem is, when using the ValidationSummary() Html helper, the validation is obviously in order of the properties in my model. Basically, because of the inheritance I have going on here, the errors are not in the correct order.
Is it possible to control when or how these validation rules are added to the list? The only attribute I'm using is Required.

I have a div where I put a lot of stuff on runtime to construct a chart. The user should be able to copy the chart to another div (innerHTML) and then make som adjustments to the original div, which causes a postback. Of cours the cloned div comes back empty.
So I'm thinking of putting the entire innerHTML in a session variable at page_unload, but then I run into the validation problem. I've tried using a hiddenfield as an in-between control, but it's the same, and it seems you can't use the CausesValidation on that control. I've also tried a regular asp:textbox, but the CausesValidation doesn't have any effect.
How to do this? Or any better way all together on the copy-chart issue?

I am developing a simple application. I have completed.
1 - Using Respositary Pattern
2 - using DataAnnotation for validation.
3 - Selecting, Creating, Updating and Deleting.
My Questions.1 - I have extra BL validation. Should I create Service layer or use that in Partial Class where my DataAnnotation is?
I dont want to use DataAnnotations in one class and other BL validation in another class. Is there a way to combine both or Should I use those separately. Confused here? Any examples to implement BL.
2 - I have lots of Calculations to run once record is reterived and insterted. Where I put these calculations? Should I make extensions and call in controller or Methods in separate file. Any clean approach.
3 - Can I use Repositary Pattern and Service model in ASP.NET webforms with ADO.NET, Entity Framework and Linq to sql?
4 - I don't know id this is stupid question. Can we use ADO.NET with DataAnnotation somehow in Webforms and ado.net with mvc?.

Is there an out-of-the-box DataAnnotation attribute that checks if an integer is greater than a certain value?
public Model
{
[GreaterThan(0)]
public int MyVal{get;set;}
}

I am having trouble with the with mvc2.
I am using the Entity Framework as my ORM. I have used the POCO Entity Generator to create POCO objects. I moved the generated objects to a separate project. I followed steps outlined here(Tutorial). This is my project structure
Sports.Data - Entity Frmework and Data Access
Sports.Entities - The poco objects generated and buddy classes
Sports.Web - The web application
In the Sports.Entities project I have created buddy classes for the generated pocos.
The problem I am having is that the attributes are being ignored by the mvc. The validation is not working and the correct label text is not being displayed. Instead of 'Shirt Size', 'ShirtSize' is displayed.
Here is the code.
<div>
<%: Html.LabelFor(m => m.Player.ShirtSize)%>
</div>
<div class="editor-field">

From my testing, it appears that the order of parameters for the UpdateParameters must match both the order of the bound fields on the form (asp:Formview), and the order of the parameters in the UpdateCommand. Is that correct? If so, why do the parameters have names if all that matters is the order? I tried both asp:ControlParameter and asp:Parameter. Maybe the more relevant question is why aren't the names used instead of the order, particularly for the form order?
So, given I display the Identity field (CID), and need that for the update, I cannot get the update to work without including it in the UpdateCommand. Of course, since it is an autonumber field in Access, I cannot actually set it. So, I had to add another field to the db (lngUpdateCID) that I could set. That can't be how it has to be done, but I could not figure out another way to do this.
The relevant code is below:

I have a table that displays a user control on each row. The user controls are strongly typed to a viewmodel which contains DataAnnotation style validation. If one of the rows has invalid data entered (lets say the 3rd row) the data annotation validates display agains the first row/user control.How do I get the data annotation to show against the relevant user control?

how do i get the [Display(Name="Some Title")] DataAnnotations "Some Title" rendered in the List scaffold view's output?
I create a strongly typed list scaffold view for this class:
public class CompanyHoliday
{
[Key] [code]...
However i don't want "Date" and "Name" in the table header - i want "Datum" and "Feiertag Name" rendered there dynamically. The actual column header titles should come from the Display Dataannotation.

I am using ASP.NET's server-side validation. In the page_load event I'm calling Page.Validate(), and if Page.IsValid is not true I'm then polling the controls to figure out which ones are not valid, and then determining what actions to take.It would be much easier if each control would raise an event as validation fails, allowing me to take action for that particular control. I'm very much a naive programmer when it comes to validation, but is there a way to extend these controls so that a validation error raises an event?

jQuery validation is working fine on my machine, when i pushed it to test server it won't it's throwing some errors which is kind of surprising.These are the errors I am getting: $.validator is null or not an object...I've never gotten this error before and it throwing an error when I declared a variable like var isValid.I don't know what to do. I am doing the custom validation methods not in the document.ready(). Does this cause this error? I wonder because all jquery validations are passing and hitting the server side validations.
