我已經添加了一個UpdatePanel環繞一個GridView並給它兩個觸發器,它們是UpdatePanel之外的按鈕。我無法獲得按鈕單擊事件來觸發GridView異步刷新。ASP.NET UpdatePanel不工作

我敢肯定,數據源正在更新,因爲F5刷新頁面顯示新的數據(這是通過文本框提交)

我也試過編程更新在代碼隱藏文件中UpdatePanelUpdatePanel1.Update(); )但是也不這樣做。

這裏是我的代碼:

看看這可以幫助你:觸發在UpdatePanel的更新通過控制​​是在不同的ContentTemplate(http://stackoverflow.com/questions/417131/trigger-an-update-of-the- updatepanel-by-a-control-that-is-in-different-contentpl) – jadarnel27

感謝您的參考,但我無法完全理解它。總結;我有一個GridView在文本框中顯示以前的條目。我希望submitBtn觸發兩個數據被髮送到Gridview的數據源,同時也是Girdview的異步更新。 爲了確保被遲添加觸發器儘可能(根據您的鏈接)我加入他們,當文本框被改變。這不知何故仍然無法工作。無論如何,儘管 – hippo30

首先確定是否有任何錯誤。對於例如有時候這將是由於沒有正確關閉html標籤。 –

你可能得到的是被吞了服務器端錯誤。要查看錯誤消息,最簡單的方法是將AsyncPostBackTrigger臨時替換PostBackTrigger
