Changing skinId on custom control HELP!

[V]

Hello!

I made custom control with tables and labels in it.
In my page I have several of these controls. Each one should have
different color of tables etc.
I have different SkinIDs for that.
When my Default page loads I'd like to set SkinID for each of these
controls.

I understand that Page_PreInit should have this but I can't access my
control's properties from there.
I also know that control can't have PreInit, only Page.

I spent last ten hours trying to get around this. I don't know what to
do. HELP

Thank you,
Hrvoje
