Can't hide base class properties

I have two controls in a DLL; one inherits from Control and the other from Form. In both cases I'd like to hide base class properties that don't make sense for the control (e.g. AllowDrop). I've read Ray Hayes' thread onHiding Properties and tried the following:
<Browsable(False), _
DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden), _
EditorBrowsable(EditorBrowsableState.Never)> _
Public Shadows Property AllowDrop() As Boolean
Get
End Get
Set(ByVal Value As Boolean)
End Set
End Property
This hides the property from the VS 2003 properties window butNOT from the code editor. Everything I've read said this should work, but it doesn't. Any help would be greatly appreciated.

The EditorBrowsable attribute will hide the property in the code window, however it does not work within the same project. Members are always shown within the same project no matter what attributes they have applied. Only referenced projects will not see the property.

Thanks for your reply. The controls are in a DLL. I'm seeing the behavior in a WinForms EXE that references the DLL. It occurs with either a binary or project reference.

If you want to hide the base class, you have to use the private access modifier. This will not allow derived classes have access to these members. If you are trying to hide the methods and want to keep them visible only in the class, use protected.

Is that what you are asking?

It looks like the EditorBrowsableAttribute only applies when you're referencing a class from a .dll that isn't in the same solution. If you feel this is not the correct behavior, please use the MSDN product feedback center to open a suggestion bug for the code editor teams.
