This should give you a rough idea of what to do.
This is code I have used with an access db to select specific data into text boxes related to the selected Datagridview row.

C#

private void DGReview_CellClick(object sender, DataGridViewCellEventArgs e)
        {
            conn.Open();
            OleDbCommand cmd = new OleDbCommand();
            cmd = conn.CreateCommand();
            cmd.CommandText = @"SELECT * FROM [Table] WHERE [Variable] ='" +    DGReview.SelectedRows[0].Cells[0].Value.ToString() + "'";
            cmd.ExecuteNonQuery();
            DataTable dt = new DataTable();
            OleDbDataAdapter adapterA = new OleDbDataAdapter();
            adapterA.SelectCommand = cmd;
            adapterA.Fill(dt);
            Object a = dt.Rows[0]["Variable"];
            textbox.Text = Convert.ToString(a);            
            
            conn.Close();
        }

Where as the method is DG_Review_CellClick yours would probably be checkbox_CheckedChanged
