How to populate the CollectionControlDialog that comes up when using the PropertyGrid's CollectionEditor (Extended WPF Toolkit)?

Using a PropertyGrid from the Extended WPF Toolkit, I need to use a CollectionEditor:

[Editor(typeof(CollectionEditor), typeof(CollectionEditor))]
public Definition DefTypes { get; set; }

But the CollectionControlDialog that appears when clicking on the DefTypes fields has no items to choose from.

So how do I populate this CollectionControlDialog?

Your CollectionEditor will only show a collection of a certain type of objects. In this case it doesnt look like you are adding the Editor attribute to a collection, but rather to a single object.

See my code below:

public class Definition {
    public string SomeProperty { get; set; }
}

public class Definitions : List<Definition> {
}

Now you will be able to apply the CollectionEditor to the Definitions:

[Editor(typeof(CollectionEditor), typeof(CollectionEditor))]
public Definitions DefTypes { get; set; }

And it will bring up the CollectionEditor with the properties defined in 'Definition'
