MVC2 DataAnnotations validation with inheritance
- by bhiku
Hi, I have a .NET 2.0 class the properties of which are marked virtual.I need to use the class as a model in a MVC2 application. So, I have created a .NET 3.5 class inheriting from the .NET 2.0 class and added the DataAnnotations attributes to the overriden properties in the new class. A snippet of what I have done is below
// .NET 2.0 class
public class Customer
{
private string _firstName = "";
public virtual string FirstName
{
get { return _firstName; }
set { _firstName = value; }
}
}
// .NET 3.5 class
public class MVCCustomer : Customer
{
[Required(ErrorMessage="Firstname is required")]
public override string FirstName
{
get { return base.FirstName; }
set { base.FirstName = value; }
}
}
I have used the class as the model for a MVC2 view using the HtmlFor helpers. Serverside validation works correctly but the client side validation does not. Specifically the validation error is not displayed on the page.
What am I missing, or is it only possible to do this using buddy classes.
Thanks.
