collection property in user control

hello folks,
i am trying to develop a control which when dropped on the form can list out out the control that are placed on the form. these controls may be a text box, combo box or the date picker.
i am successfull to get the names but i would like to store the text box in a collection and can be accessed by some method of the control.

you can think of the list property that is implements in the combobox or the listbox. the user can add the items in the design mode and cam access by useing the list property or can add to its exsisting by additem method.

waiting for the reply
