SQL Server で行を更新する際に問題に直面しています

ストアド プロシージャを使用して、グリッドから SQL Server データベースのテーブルに列を更新する場合、onclick(更新用の) ボタンに問題があります。イベントを呼び出しRowUpdatingます...問題は、そのイベントへのアクセスがないことです...最初の行にMsgBoxを配置したため..何も起こりませんでした

これはコードです：

asp .net コード:

<asp:GridView ID="DossierGV" runat="server" AllowPaging="True" 
              AllowSorting="True"  AutoGenerateColumns="False" 
              DataKeyNames="ID_Dossier" onrowupdating="DossierGV_RowUpdating" >
   <Columns>
      <%--       <asp:BoundField DataField="Nom_Giac" HeaderText="Nom_Giac" 
                          SortExpression="Nom_Giac" />--%>
      <asp:CommandField ShowEditButton="True" UpdateText="Modifier "></asp:CommandField>
      <asp:CommandField ShowSelectButton="True" />
      <asp:TemplateField HeaderText="ID_Dossier" SortExpression="ID_Dossier">
         <EditItemTemplate>
            <asp:Label ID="Label1" runat="server" Text='<%# Eval("ID_Dossier") %>'></asp:Label>
         </EditItemTemplate>
         <ItemTemplate>
            <asp:Label ID="Label1" runat="server" Text='<%# Bind("ID_Dossier") %>'></asp:Label>
         </ItemTemplate>
      </asp:TemplateField>
      <asp:TemplateField HeaderText="ID_Entreprise" SortExpression="ID_Entreprise">
         <EditItemTemplate>
            <asp:Label ID="ID_Entrepriselbl_Edit" runat="server" Text='<%# Bind("ID_Entreprise") %>'></asp:Label>
         </EditItemTemplate>
         <ItemTemplate>
            <asp:Label ID="ID_Entrepriselbl_Item" runat="server" Text='<%# Bind("ID_Entreprise") %>'></asp:Label>
         </ItemTemplate>
      </asp:TemplateField>
    ..... (lots more <asp:TemplateField) ..........
   </Columns>
   <SelectedRowStyle BackColor="#F2E488" Font-Bold="True" />
