好象列标题就是字段名吧

Conn conn=new Conn();
string Course="select * from course";
OleDbDataAdapter CourseAdapter=conn.GetDataAdapter(Course);
CourseAdapter.Fill(Dataset,"course");

string Teacher="select * from teacher";
OleDbDataAdapter TeacherAdapter=conn.GetDataAdapter(Teacher);
TeacherAdapter.Fill(Dataset,"teacher");

string CourseTeacher="select * from courseteacher";
OleDbDataAdapter CourseTeacherAdapter=conn.GetDataAdapter(CourseTeacher);
CourseTeacherAdapter.Fill(Dataset,"courseteacher");

dtCourseTeacher=new DataTable("dtCourseTeacher");
dtCourseTeacher.Columns.Add("id",typeof(int));
dtCourseTeacher.Columns.Add("teaid",typeof(int));
dtCourseTeacher.Columns.Add("teaname",typeof(string));
dtCourseTeacher.Columns.Add("couid",typeof(int));
dtCourseTeacher.Columns.Add("couname",typeof(string));

请问，如何能够转到树形生成器界面呢？好像是右健点击该datagrid但是，我用的是2003.net只能选择属性，但是在属性那个里面就没有可以“选择列”这样的操作哦？？能说的更明白些吗：？我问过朋友，他也像你这样回答，可是我怎么也没有属性生成器可以让我选择列这样的冬冬啊。。。郁闷。。。。555555555555555
