ComboBx Displaymember Problem

Hi


I created my own combo control by inheriting the
system.windows.forms.combobox control and adding some extra properties.
I have two (2) issues:

1. For some raison when I set up the DisplayMember Property to the
“Something� it turn it self back to empty string “� and Don’t know what am I
doing wrong.
2. Also I would like to be able to manage what is displayed on the textbox
part of my combobox i.e. concatenating 2 or more fields of a bounded
datatable.

Does anyone know what function or sub of the system.windows.forms.combobox
should I override to handle what is displayed on the text portion of my
control when the selected Item changes.

Thanks for your help.
