Custom Component Design Time Array Property Question. . .

note: abbreviated code for clarity

I have a class Definition that implements IDefinition -

public interface IDefinition {    int Width {get;set}    string Caption{get;set} }

I have an enumeration

public enum Foobar{foo, bar,}

I have a component, MyComponent that has a public Array property Definitions and FoobarType:

public MyComponent:Component {   private Definitions[] _defs = new Definition[]{new Definition(),new Definition()};   private Foobar _foobar = Foobar.foo;   [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]   public Definitions[] Definitions    {     get { return _defs;}     set { _defs = values;}   }      public Foobar FoobarType    {     get {return _foobar;}     set     {       if ( (_defs !=null) && (_foobar==value)) return;       switch (_foobar)       {         case Foobar.foo:           /* Make two definitions */           _defs = new Definitions[]{new Definitions(),new Definitions()};                break;         case Foobar.bar:            /* Make one definition */           _defs = new Definitions[]{new Definitions(),new Definitions()};           break;       }     }   } }

the idea is. . . when in designmode, if I choose to set the FooBarType to foo, I want Two definitions, if Bar, I only want one. And I want the designer to let me set the Width and caption of the definitions. . .

the DesignerSerializationVisibility attribute lets me interface the Definitions via the designer, I want that when I change the foobartype property using the designer, the definitions reinitialize but this doesnt happen. . . .

any suggestions
