Specially for two guys from DevCon'12 with whom we chatted a lot about XAF
Here you go:
public abstract class ObjectViewController<ViewType, ObjectType> :
ViewController<ViewType> where ViewType : ObjectView {
public ObjectViewController()
: base() {
this.TargetObjectType = typeof(ObjectType);
}
public ObjectType ViewCurrentObject {
get { return (ObjectType)View.CurrentObject; }
}
}
For people who do not quite understand what is going on, this is a new short way of declaring a ViewController in code to target it for a certain business object and View type at the same time.
So, starting with 12.1, you can write the following code:
public class MyCoolViewController : ObjectViewController<DetailView, Contact> {
protected override void OnActivated() {
base.OnActivated();
Contact theContact = ViewCurrentObject;
}
}
Enjoy! And generics rock!
