This might not be the best group for this question but I don't know where
else to post.

I've designed a control and I'm trying to setup a designer for it.

My issue right now is that I'm need "dynamic" properties so that when one
property is modified it will change another property.

Really all I'm doing is hiding some properties and showing others depending
on a value. If true it will hide set X and show set Y else it will show X
and hide Y. The reason for this is just to reduce the number of properties
when many are not necessary.

I am trying to do this in Pre/PostFilterProperties but these do not get
called when a property is changed.

Is there any way I can do what I want? (In some way I need to update the
properties list when a property is changed and not just before or after the
control is created)

Thanks,
Jon
