Hi Bill,

I'm doing something like this in my custom controls designer
I didn't try compiling it but I just modified it from some of my code
so hopefully it works.

private DesignerVerb SomeVerb;

public override void Initialize(IComponent component)
{
    base.Initialize (component);

    ISelectionService ss =
(ISelectionService)GetService(typeof(ISelectionService));

    if (ss != null)
        ss.SelectionChanged += new EventHandler(OnSelectionChanging);

    this.SomeVerb = new DesignerVerb("Invoke SomeVerb", new
EventHandler(SomeVerbHandler));
}

public void OnSelectionChanging(object sender, EventArgs e)
{
    ISelectionService ss =
(ISelectionService)GetService(typeof(ISelectionService));

    if( ss.PrimarySelection is Button ||
       ss.PrimarySelection is Label
    {       
        IDesignerHost dh = (IDesignerHost)
this.GetService(typeof(IDesignerHost));
        IDesigner dsgnr = (IDesigner)dh.GetDesigner(
(Control)ss.PrimarySelection );

        if( !dsgnr.Verbs.Contains() )
            dsgnr.Verbs.Add(SomeVerb);
    }
}

private void SomeVerbHandler(object sender, EventArgs e)
{
    MessageBox.Show("Do Something");
}

kind regards,
Jerron
