What you have tried so far?

Did you try addItem()?

in the initialize() method i didn't add addItem but i declare addElement like u see at the bottom

private void initializeDB(){
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
conTARCollegeDB = DriverManager.getConnection("jdbc:odbc:TARCollegeD S");
stmtInitialize = conTARCollegeDB.createStatement();
stmtSearch = conTARCollegeDB.createStatement();
stmtInsert = conTARCollegeDB.createStatement();
stmtUpdate = conTARCollegeDB.createStatement();
stmtDelete = conTARCollegeDB.createStatement();
rsStudent = stmtInitialize.executeQuery("SELECT StudentID FROM Student;");

while (rsStudent.next()){
String studentID = rsStudent.getString(1);
dcbomStudentID.addElement((Object)studentID);
}
}
}
catch(Exception ex){
JOptionPane.showMessageDialog(null, "Error in connecting to database...");
}
}

but i can only retrieve data(Student ID) for combobox...how to retrieve from the other column such as Student Name,CourseID tat match the student ID?thx

You have to use the correct query to retrieve data you want.
