ここで少し問題があります。次のマスターテーブルがあります

M_従業員

EMPID    Name

1      abc
2      xyz

M_区分

DIVID  EMPID  DIVISON

1        2      arts
2        1      science

M_指定

DESGID  EMPID  Designation

1         2      Teacher
2         1      Scientist

マスターテーブルに存在するIDに基づいて、フォームのラベルのいくつかのフィールドを取得します....フォームのこれらの値を新しいテーブルに保存するときに、IDのみを保存したいですフォームのラベルに表示されているテキスト値ではありません.以下は私が試したコードです..誰か助けてくれますか?

部門と指定を読み込むときは、ID をこのクラスのプライベート ファイルなどのどこかに保存します。 

public partial class temporaryduty : System.Web.UI.Page
{
  private int divisionId;
  private int designationId;

...

if (objDs.Tables[0].Rows.Count > 0)
{
  lbldiv.Text = objDs.Tables[0].Rows[0]["DIVISION"].ToString();
  lbldesig.Text = objDs.Tables[0].Rows[0]["Designation"].ToString();
  divisionId = objDs.Tables[0].Rows[0]["Expr1"];
  designationId = objDs.Tables[0].Rows[0]["Expr2"];
}

次に、ボタンをクリックして、これらのフィールドを使用して ID を挿入します。

 cmd.Parameters.AddWithValue("@DIVID", divisionId);
 cmd.Parameters.AddWithValue("@DesigID", designationId);
