Design time editors and CodeDom serialization

[AP Farszha]

Hello groovers,

I have a component which i'm trying to add some design time support to. I
wish to add design time support so that a readonly collection of
ToolStripItems can be maintained via a collection editor however i only wish
to expose the following interface to the design time editor. Also the editor
that maintains the readonly collection can only add ToolStripItems that
already exist on the parent form that contains the component and cannot
create new ToolStripItems:

public CommandActionLi st
{

public ReadOnlyCollect ion<ToolStripIt emControls
{
get;
}

public void AddControl(Tool StripItem value) {}

public void RemoveControl(T oolStripItem value) {}

}

I've created a class:

CommandActionLi stCodeDomSerial izer : CodeDomSerializ er
{
public override object Serialize(IDesi gnerSerializati onManager manager,
object value) {}
}

which serializes the objects in the collection into the
InitializeCompo nent() method, ie the Serialize(...) method generates lines
of code similiar to the following for each item in the Controls collection:

this.fooCommand ActionList.AddC ontrol(fooToolS tripItem);

what i'm unsure of is how to create the editor:

Should i be deriving from UITypeEditor, or CollectionEdito r, instead of
exposing a Readonly collection should i implement ICustomTypeDesc riptor to
expose a property which can be maintained?

thanks
