    in this line DALCourseRequirdDocument.GetStudentEduDoc(RegID);

    what ” DALCourseRequirdDocument ” stands for?

      Thanx for comment…
      which is object class where we get the data from database.
      you can also get data directly from database through Select Query and save in Dataset and pass here dataset to Control.
