Hide property in Collection Editor

[Simon]

Hi

I have developed a custom webcontrol like a Table (A) with a rows collection
property (collection derived from CollectionBase) where I put one or more
custom webcontrol (B).
I need to hide some public property on controls (A) & (B) when in Design
Mode.
For the control (A) I have create class derived from ControlDesigner , I have
override the PostFilterPrope rties method typing inside some code for
removing the properties from properties dictionary, and after I have set
Designer attribute on class declaration for the control (A) and this work
fine. (see source code)
For the control (B) I try to make same technique but this don't work on
CollectionEdito r form.
Plwase if some one have some sample code to do this, please reply to me.

Thanks in advance

Simon.
