在頁面加載時看不到asp.net gridview

我有一個gridview，它不會在頁面加載時顯示。 GridView是在一些更新面板內部的asp：Panels內部。我瀏覽了代碼，所以我知道gridview有數據行。如果我將GridView移動到面板之外並更新面板，那麼它將顯示數據。有人知道爲什麼它不在下面的面板和更新面板中工作嗎？在頁面加載時看不到asp.net gridview

你有綁定數據源嗎？ – 2012-07-18 16:24:37

是的。正如我上面所說的，我確信gridview有數據，如果我將gridview移到所有面板之外並更新面板，那麼它工作正常，它會顯示數據。如果我把它放在面板裏面，它不會顯示出來...... – user1202606 2012-07-18 16:26:43

你添加了ScriptManager嗎？ – 2012-07-18 16:32:46

不知道，但這種增加可能幫助你

<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true" />

2012-07-18 16:35:28

我已經在母版頁上有一個腳本管理器，我添加了enablePartialRendering = true，但沒有工作..... – user1202606 2012-07-18 16:43:30

@ user1202606：發佈您的服務器端代碼即（綁定gridview）。 – 2012-07-18 16:48:23

我剛剛在上面貼出來。我知道它正在填充網格，正如我最初所說的那樣，如果我將GridView移動到面板之外並更新面板，它就會顯示出來並填充。如果我單步執行代碼，我可以看到它有數據，它在面板和更新面板中不會顯示。 – user1202606 2012-07-18 16:50:53

似乎你的更新面板不被觸發您數據綁定在GridView後

嘗試：

<asp:UpdatePanel ID="updTankDetail" runat="server" UpdateMode="Conditional">

然後在你的代碼放在後面

updTankDetail.Update()

2012-07-18 16:58:27

沒有工作，它看起來像是在尋找名爲extendercontrolbase.cs的文件。可能是ajaxcontroltookit的一部分.... – user1202606 2012-07-18 17:15:08

如果你得到這個錯誤，你可能有一些缺少ajax文件。嘗試重新安裝ajax可能是件好事。 – 2012-07-18 17:19:22

我現在正在嘗試，謝謝.... – user1202606 2012-07-18 17:28:26

代碼背後：

On pageLoad() 

if (!Page.IsPostBack) 
     { 
      DataTable dtfetch = emp.Fetchreord(); 
      gvempgrade.DataSource = dtfetch; 
      gvempgrade.DataBind(); 
     }

注：當你得到相關extendercontrolbase.cs意味着DLL缺少錯誤，試評的所有擴展的控制和看是否有效

標題：無法看到頁面加載的asp.net gridview 我在代碼中看到您使用的面板與id="ID="pnlTankDetail""和麪板ID="pnlTankDetail"有屬性Visible =「False」so the gridview grdTanks can't show in page load. You should change to Visible =「true to see gridview. Andi think the div tag not have property runnat =」server「`。希望這個幫助。
