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 ())); }
