Hi Dario,
it's actually not that easy; Maybe I should describe the scenario a
bit more detailed. This is my Class:
public Contact {
public int Id;
[Valid]
public IList<CommunicationItem> Com;
}
public class CommunicationItem {
public int Id;
public MyCustomClass CommunicationType;
public string CommunicationString;
}
public MyCustomClass {
public int Id;
public String Type; // For example "eMail"
public string Regex; // <= Rules are stored in here!
}
Then I'd like to validate the CommunicationItem - Object. Using
CommunicationItem.MyCustomClass.Regex as the Key. If I use my custom
EntityValidator, it's validating, but MVC does not know of course what
Property failed the validation...
By Using [Pattern(...)] its not possible to access any Property of the
class... And if I create a ValidationClass which iterates through the
IList, it stops after the first element which is invalid because I
have to return "false"...
Any Idea how to solve this?
Thanks so much!
