View 3 Repliesthe use of data annotations. when should we not use . or how should i use it when there are two or more tables on the form?
View 3 RepliesI 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?.
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]....
Is there any support from JQuery for DataAnnotations?Found this but not sure if its supporting. http://bassistance.de/jquery-plugins/jquery-plugin-validation/
View 2 RepliesIs 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">
[Code]....
, what wrong with my code below, look:
In my model,[Code]....
and in my aspx, [Code]....
But does't work, why?

How can I maintain using data annotation attributes for validations in mvc3 different requirement for edit and create in an elegant manner. I have an different edit and create requirement.
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.
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?
View 1 Replieshow 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.
