.aspxページは次のようになります

<form id="Form1" runat="server">  
<asp:Repeater ID="Repeater1" runat="server">
    <HeaderTemplate>
            <table border="0" width="600px" cellpadding="2" cellspacing="1" style="border: 1px solid maroon;">
        <tr bgcolor="maroon">
            <th>    Subject_Id    </th>
            <th>    Subject_Name    </th>
            <th>    Fill_Marks    </th>
        </tr>
</HeaderTemplate>

<ItemTemplate>
    <tr>
        <td width="100">
                <asp:TextBox ID="Subject_Id" runat="Server" Text='<%#Eval("Subject_Id")%>'></asp:TextBox>
        </td>
        <td>
                <asp:TextBox ID="Subject_Name" runat="Server" Text='<%#Eval("Subject_Name")%>'></asp:TextBox>
        </td>
        <td>
                <asp:TextBox ID="Marks" runat="server"></asp:TextBox>
        </td>
    </tr>
</ItemTemplate>

    <FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>

    <asp:Button ID="btnInsert" runat="server" onclick="btnInsert_Click" Text="Insert" CommandArgument="" CommandName=""/>
    <asp:Button ID="btnUpdate" runat="server" onclick="btnUpdate_Click" Text="Update" CommandArgument="" CommandName=""/>    

    </form>

C＃-コードビハインド...

  protected void btnInsert_Click(object sender, EventArgs e)
  {
   cn = new SqlConnection(ConfigurationManager.ConnectionStrings["DbConnect"].ConnectionString);
   cn.Open();

  foreach (RepeaterItem item in Repeater1.Items)
  {
      TextBox Subject_Id = (TextBox)item.FindControl("Subject_Id");
      TextBox Subject_Name = (TextBox)item.FindControl("Subject_Name");
      TextBox Marks = (TextBox)item.FindControl("Marks");

      SqlCommand cmd = new SqlCommand("Insert into result VALUES (id='"+@Subject_Id+"',name='"+@Subject_Name+"',marks='"+@Marks+"')", cn);

      Repeater1.DataSource = cmd.ExecuteReader();
      Repeater1.DataBind();

      cn.Close();
      cmd.Connection.Close();
      cmd.Connection.Dispose();
  }
}

次に、そのデータを次のテーブルに挿入します。

result_table

id    varchar(10)
name  varchar(20)
marks varchar(3)

挿入および更新機能を実行して、データベースからデータを取得するにはどうすればよいですか...簡単な方法で？？ありがとう...

ボタンタグにいくつかのプロパティを挿入します：CommandArgument = "" CommandName = ""

Repeater1.ItemCommand +=new RepeaterCommandEventHandler(Repeater1_ItemCommand);

protected void Repeater1_ItemCommand（object source、RepeaterCommandEventArgs e）{書き込みたいコード.........}という名前の関数を作成します

次のようにbtnInsert_Click関数を実装します

**新しい機能に従って編集

  protected void btnInsert_Click(object sender, EventArgs e)
  {
    String connectionString = ConfigurationManager.ConnectionStrings["DbConnect"].ConnectionString;
    String queryString = "";
     using (SqlConnection connection = new SqlConnection(connectionString))
    {
        foreach (RepeaterItem item in Repeater1.Items)
       {
        TextBox Subject_Id = (TextBox)item.FindControl("Subject_Id");
        TextBox Subject_Name = (TextBox)item.FindControl("Subject_Name");
        TextBox Marks = (TextBox)item.FindControl("Marks");

        queryString = "Insert into result VALUES (id='"+@Subject_Id+"',name='"+@Subject_Name+"',marks='"+@Marks+"')";

        SqlCommand command = new SqlCommand(queryString, connection);

        // execute the query to update the database
        cmd.ExecuteNonQuery();
        }
    }
    //call the function to load the gridview if it is lost on postback.
  }

ボタンのクリックでアクションを簡単に繰り返すことができるように、データベースとグリッドビューの入力コードを別々の関数に移動することをお勧めします。
