MyDropDownList.Datasource = [your datasource]; MyDropDownList.DataTextField = blah ; MyDropDownList.DataValuefield = blah ; MydropDownList.DataBind(); //Do this. foreach (YourObject instance in YourObjectList) { MyDropDownList.Items.add( new ListItem (YourObject.column1+Yourojbect.colum2+Yourobject.Column3 Yourobject.DataKey)); } for example you can do DVU_eventsTableAdapter events = new DVU_eventsTableAdapter(); DataTable dt = events. GetData (); for ( int i = 0 ; i Rows . Count ; i++) { DateTime eventdate = new DateTime (); eventdate = Convert . ToDateTime (dt. Rows [i][ event_date ]. ToString ()); string formatted_date = String . Format ( {0:d}  eventdate); ddlEvent. Items . Add ( new ListItem (dt. Rows [i][ loc_city ]. ToString () +   + dt. Rows [i][ loc_state ]. ToString () +  ( + formatted_date + )  dt. Rows [i][ event_id ]. ToString ())); }
