OnPreRender not getting called in control

[Winista]

[ASP.Net 2.0]

I am creating a composite control. It contains another custom control. There
is some implementation in OnPReRender event of the contained control. When
my composite control is rednered, OnPreRender event is not getting raised in
the conatined custom control. What do I need to do so that PreRender event
gets raised in conatined control?

Thanks

Doh!
My fault. I forgot to add the contained control in the composite control's
collection in CreateChildControl method.
