Under VB6 this property returns the controls contained in the form that contains the current UserControl. The ParentControlsType property exposed by this collection permits to determine whether the actual controls or the Extender wrappers of those controls should be returned.

VB.NET doesn’t support anything similar to the ParentControls collection. VB Migration Partner returns a collection that includes all the controls contained in the parent form, including the form itself. The returned collection exposes the ParentControlsType property, but assigning a value to this property has no effect on the items in the collection itself.
