GridView在編輯模式行

我之前發佈過類似的問題，但我仍然有一些問題。我使用asp.net 4和c＃。GridView在編輯模式行

請幫我理解當用戶單擊單行的EDIT按鈕時，我需要更改Label uxTest的TEXT。

有什麼想法？再次感謝球員，並抱歉，如果看起來像一個重複的問題。

代碼解決方案：

if (e.Row.RowType == DataControlRowType.DataRow && 
        (e.Row.RowState & DataControlRowState.Edit) == DataControlRowState.Edit){ 
Label dl = (Label)e.Row.FindControl("uxLblTest");// Retrive control here 
}

爲什麼不編輯您之前的問題然後......或至少給我們的鏈接？ – 2011-03-02 16:16:41

對不起，我沒有想過，現在我做到了。請試試這個代碼。我幾乎花了兩天的時間，但沒辦法能夠得到這個標籤。有任何想法嗎？非常感謝 – GibboK 2011-03-02 16:19:53

我感到沮喪，但是您可以嘗試減少代碼量嗎？ – 2011-03-02 17:41:51

爲什麼你需要去改變它，你的ItemTemplate和EditItemTemplate裏可以有完全不同的數據/控制。在下面，我爲項目/編輯模板顯示了2個不同的標籤（請參閱ID）。您可以隨意更改，但這是具有不同查看/編輯模式的基本方法。

  <asp:TemplateField HeaderText="Test Column"> 
       <ItemTemplate> 
        <asp:Label ID="uxTest" runat="server" Text='<%# DataBinder.Eval(Container, "DataItem.TestColumn") %>'> 
        </asp:Label> 
       </ItemTemplate> 
       <EditItemTemplate> 
        <asp:Label ID="uxTestEditMode" runat="server" Text='<%# DataBinder.Eval(Container, "DataItem.TestColumn") %>'> 
        </asp:TextBox> 
       </EditItemTemplate> 
      </asp:TemplateField>
