的DetailView更新不工作

我用Google搜索每一個地方，但沒有一個明確的答案我嘗試使用下面的代碼使用詳細信息視圖更新記錄：的DetailView更新不工作

當我改變where子句是「凡·REC_ID = 2" 它的工作原理，但使用參數時它不這樣做所需的更新任何幫助，請

嘗試改變這一點： briskovich

沒有它沒有工作 –

嘗試這個。使您的Rec_Id成爲標籤而不是文本框。幾周前我遇到了這個問題，而且工作。和 convert（varchar，rec_id）LIKE @rec_id。 – briskovich

我發現解決方案如下：

1-在where子句中：將Rec_ID更改爲任何其他名稱，例如ID。

之前：UpdateCommand="Update Contacts Set [email protected]_No Where [Rec_ID][email protected]_ID">

後：UpdateCommand="Update Contacts Set [email protected]_No Where [Rec_ID][email protected]">

2-在UpdateParameters獲得ID的值，作爲這樣的：

之前：<asp:Parameter Name="Rec_ID" Type="Int32" />

後：<asp:ControlParameter ControlID="DetailsView1" Name="ID" PropertyName="SelectedValue" />

此將允許您將Rec_ID保持爲只讀或甚至在DetailsView刪除隱藏它

感謝大家

private void OnDetailsViewItemUpdating(object sender, DetailsViewUpdateEventArgs e) { 
     if (String.Equals((string)e.NewValues["firstName"], "john", StringComparison.OrdinalIgnoreCase)) { 
      // "John" is not a valid name, so change it to "Steve": 
      e.NewValues["firstName"] = "Steve"; 
     } 
     if (String.Equals((string)e.NewValues["lastName"], "doe", StringComparison.OrdinalIgnoreCase)) { 
      // If "Doe" is the last name, cancel the whole operation 
      e.Cancel = true; 
     } 

}

你必須寫‘onItemUpdated’不onitemupdated。檢查案例。

希望這可以幫助你。 DetailsView控件的ItemUpdating事件的參數既包含原始數據（如果可用），也包含用戶輸入的新數據。下面是如何檢查數據並可選擇修改它的示例

因此，我們必須使用代碼後面做更新，詳細視圖上的microsoft實例不用任何，他們只是在asp控件上繼續做這個工作 –

後面的代碼是需要更新的。 – Monika
