Removing embedded objects from containers.

General

I have a Container Control that I embed objects in during the painting of the control.
How do I removed these controls from the container to start fresh?

for each ev in mEntitiesViews ev.EmbedWithin(v, x, 0, w, h) next

So how do i clear out and existing objects before repainting?
