DataGridView

I have B.Items to use as field or criteria sort and filter A.Column[j]

public void sorting(DataGridView A, ComboBox B, string Column)
        {
            query = "Select * from schTable ";
            static string path = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + Application.StartupPath + "\\dBase.accdb";
            OleDbCommand cmd = new OleDbCommand();
            OleDbDataAdapter adt = new OleDbDataAdapter();
            OleDbConnection con = new OleDbConnection(path);
            DataTable dt = new DataTable();
            DataSet ds = new DataSet();

            DataObjectsInitialization();
            con.Open();
            cmd.Connection = con;
            cmd.CommandType = CommandType.Text;
            cmd.CommandText = query;
            adt.SelectCommand = cmd;
            adt.SelectCommand.ExecuteNonQuery();
            con.Close();
            adt.Fill(ds);
            dt = ds.Tables[0];

            for (int i = 0; i < dt.Rows.Count; i++)
            {
                if (dt.Rows[i].Cells[Column].Value.Equals(B.SelectedItem))
                {
                  //A.Clear();
                  //A.Rows.Add(dt.Rows[i].Cells[Column]);
                }
            }
        }

From dt = ds.Tables[0]; my codes do not communicate anymore; all pleasure will be mine if you can assist me to:
1. Access the DataTable like DataGridView.
2. Clear or delete rows from DataGridView at run time while the DataSource equals dataBase?
Thank you.
