Searching option in VSFlexgrid

I am using VSFlexgrid in my application. To select a products in flexgrid, I need to use search & select option in VSFlexgrid. I tried using "BuildColCombolist" "ColCombolist" but all are loading the data from access as a combo box. I want to search data from a list not in a combo box. Any body having a solution for this?
