Collection Control

Question

Guys, I am in the process of creating a user control (Something like a datagrid). I have already written all the properties and methods for the user control. Now I want to give the developer the option to edit the properties of the control using Collection Editor. (The developer should be able to edit the properties of the column at design time simply by choosing a column and editing its corresponding properties). Has anybody ever worked on creating a Collection Editor?. I was looking for some help all over the web but no use. Any help in this issue will be greatly appreciated. unbreakable.
