Hello and how are you doin, i have my BLL aligned as below

using System;
using InfoDataSetTableAdapters;

[System.ComponentModel.DataObject]
public class StudentBLL
{
    private StudentTableAdapter _studentAdapter = null;
    protected StudentTableAdapter Adapter
    {
        get
        {
            if (_studentAdapter == null)
                _studentAdapter = new StudentTableAdapter();

            return _studentAdapter;
        }
    }

    [System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Select, true)]
    private InfoDataSet.StudentDataTable GetStudents()
    {
        return Adapter.GetStudents();
    }
}

 

When i go to my ObjectDataSource to select the method, its not in the dropdownlist. I wonder what problem is in my BLL
