I have a custom UITypeEditor for a property of type collection of a
component. I have created a form with a propertyGrid to edit values of each
Item of this collection, and I call it in EditValue of my custom editor.

Each item has a property of type Control, and I'd like to retrieve the
controls which are on the edited form (the form which own the component) in
order to assign one of them to the control propriety. But when I click on
this propriety, no control is displayed.

How can I retrieve the list of controls of the edited form and indicate to
the PropertyGrid that these controls can be assigned to the item propriety ?

Thanks in advance
