You need to add parameters to the SqlCommand not to the crystal report.
SqlCommand cmd = new SqlCommand("GET_ORDER_RESULT_PRINT_CASH", cn);
cmd.Parameters.AddWithValue("@ORDER_ID", TXTORDERID.Text);
cmd.Parameters.AddWithValue("@deptid", TXTDEPTID.Text);
SqlDataAdapter sda = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
sda.Fill(dt);
