how do i cast this?
the only thing difference in ReplacableControlCollection from the
original ControlCollection is an added sub "replace()".

you can't cast down unless the thing actually *is* of that type. what
do you want to do?

[quoted text, click to view]

actually i'm trying to create a ReplacableControlCollection and override
the webcontrol.controls with it.

i'm in need of a webcontrol.controls.replace(oldcontrol,newcontrol)
function to replace one control with the other while maintaining the
position in the controls hiarchy.

i don't have the code anymore, because i've solved it a different way
(copyattributes).
