Actualize a reportview on run time

Question

Hi!


With these code I can actualize my datagrid.

            conn.Open();

            OleDbCommand cmd = conn.CreateCommand();

            cmd.CommandType = CommandType.Text;

            cmd.CommandText = "select [date],[name] from 1";

            cmd.ExecuteNonQuery();

            DataTable dt = new DataTable();

            OleDbDataAdapter da = new OleDbDataAdapter(cmd);

            da.Fill(dt);

            conn.Close();

            dgvPorData.DataSource = dt;

Then I am asking question how can I actualize on time a reportview on my form. In other word if I update one data (or some datas) on the same form. How can actulize on run time.
