    Hi,
    I have 3 tables named
    1-country(countryid,name)
    2-state(stateid,countryid,name)
    3-city(cityid,countryid,stateid,name)

    and the table named address which have(countryid,stateid,cityid,street) 
    All 3 above tables are binded to grid as a combobox column.and address table binded as datasource to the grid everything is fine BUT
    how can I relate first 3 combobox together when user select its country from first combo then state combo populate its related states automatically?
