      <tr> 
       <td>

      </tr> 
      <tr> 
       <td> 
        <asp:Label ID="lblError" runat="server" /> 
       </td> 
      </tr> 
     </table> 
    </div>

後面的代碼頁是：

protected void btnSubmit_Click(object sender, EventArgs e) 
    { 
     lblError.Text = "no code"; 
    }

當我點擊提交按鈕，我得到兩個標籤錯誤和requiredfield驗證者

我得到的輸出是這樣的：

我不想用Requiredfield打後面的代碼提交事件驗證器

你使用更新面板嗎？如果是這樣，你的標記的哪一部分在裏面？ – Andrei

@Andrei：OP正在使用'ajax：CalendarExtender'，因此需要'ScriptManager'。我相信OP不使用任何更新面板。 – Prabhat

默認情況下，不需要添加'EnableClientScript =「true」'它總是'true'。 – Prabhat

我跑進魔女添加一個ScriptManager到網頁同樣的問題，打破了RequiredFieldValidator的驗證。我找到的解決方案是向ScriptManager添加一些ScriptReference。

<asp:ScriptManager ID="ScriptManager1" runat="server"> 
     <Scripts> 
      <asp:ScriptReference Name="jquery" /> 
      <asp:ScriptReference Path="~/Scripts/WebForms/WebUIValidation.js" /> 
     </Scripts> 
    </asp:ScriptManager>

您的ScriptReference路徑和名稱可能與我的不同。
