Hi,

 I'm having trouble using the ITrackSelection interface/service.  From
within my custom RootDesigner, I'd like to substitute the set of components
being designed with a different set of objects that I'd like to appear in
the 'Properties Window'.  My understanding is that all I need to do is to
call ITrackSelection.OnSelectChange(...) with my own SelectionContainer.
I'm doing this and I've confirmed that my new objects are in the container
however, they are not appearing in the properties window, the original set
of components are still there.  I'm calling 'OnSelectChange' from within an
'ActiveDesignerChanged' event from IDesignerEventService.

Is it valid to call this method from a custom root designer?  It looks like
'OnSelectChange' is being called after my call with the original components
and it's undoing my call.  Where should I be calling 'OnSelectChange' for my
root designer?

Thanks,

Joe

*************** SAMPLE CODE ************************

Here's my sample code that is a method on my Package:
void designerEventSvc_ActiveDesignerChanged(object sender,
ActiveDesignerEventArgs e)

{

IDesignerHost activeHost = e.NewDesigner;

if (activeHost != null)

{

IDesigner rootDesigner = activeHost.GetDesigner(activeHost.RootComponent);

Debug.Assert(rootDesigner != null, "Root designer is null");

if (rootDesigner is StyleRootDesigner) // one of my root designers

{

IContainer container = ((StyleRootDesigner)rootDesigner).ExampleContainer;
// my selection container w/ different set of objects.

STrackSelection trackSelSvc =
(STrackSelection)activeHost.GetService(typeof(STrackSelection));

if (trackSelSvc != null)

{

((ITrackSelection)trackSelSvc).OnSelectChange(null);

selContainer.SelectableObjects = container.Components;

selContainer.SelectedObjects = container.Components;

((ITrackSelection)trackSelSvc).OnSelectChange(selContainer);

}

}

}

}
