感謝您瀏覽此內容。UpdatePanel無法在父級GridView項目模板內工作
背景 - 在我們的項目中有一個共享點2013可視化Web部件。它有4個嵌套的GridViews在一起。點擊一個圖像按鈕3個網格將會擴大。點擊該圖像按鈕後，人口也會被編碼。但是，由於有背教發生，頁面閃爍，所有網格都變得收縮。因此，我決定在第2個網格的項目模板內部的這些網格之上保留一個更新面板。
問題 - 將它放置在那裏後，我可以停止頁面閃爍。它不會再發回帖子，點擊上述圖片按鈕。但是，網格不顯示。在所有。我通過評論更新面板來查詢我是否獲取數據。是的，我正在獲取數據。它正在顯示。但是，一旦打開更新面板，網格又不會再顯示。

我嘗試儘可能多的東西，但我沒有嘗試過，但沒有結果。你能弄清楚，我在這裏錯過了什麼？正在停止顯示網格。
這是在SharePoint以外的相同行爲（在純ASP.NET環境中）還是僅在SharePoint？ –
這是一個Visual Web部件，因此只能在SharePoint中使用。我還沒有嘗試與ASP.Net – user2375504
我認爲，你應該嘗試。如果它在純粹的asp.net環境中出現同樣的錯誤 - 它不是特定的SharePoint。 Google有一些關於templatefield裏面的updatepanel的線程。 –
