Subject: CollectionEditor - Add/Remove buttons are disabled



Hi,

Could you please suggest me some changes?

I've got the following code, which represents the small component with
collection property:

class Test : Component

{

private BindingList<Item> items = new BindingList<Item>();



[Editor(typeof(CollectionEditor), typeof(UITypeEditor)),


DesignerSerializationVisibility(DesignerSerializationVisibility.Content)
]

public IList<Item> Items

{

get { return items; }

}

}



class Item

{

private string name;

public string Name

{

get { return name; }

set { name = value; }

}

}



Unfortunately, Add and Remove button in CollectionEditor popup dialog
are disabled. Why?

I tried to inherit from Collection Editor and use the following editor:

public class ItemCollectionEditor : CollectionEditor

{

public ItemCollectionEditor(Type type)

: base(type)

{

}



protected override Type CreateCollectionItemType()

{

return typeof(Item);

}

}



It didn't change anything? What's wrong about this snippet?

-- thanks
