我目前正在使用帶有選項卡的網頁。我在此代碼中實現更新面板的目的是爲了防止當我按下任何按鈕時當前跳回第一個選項卡的選項卡。我在每個添加和保存的標籤中都有2個圖像按鈕。在實現更新面板後，添加按鈕正在工作，因爲它能夠向網格視圖添加新行並保留在同一個選項卡上，但保存按鈕不起作用，並且在單擊後沒有任何效果。我目前是ASP.NET C＃的新手。希望從StackOverFlow獲得幫助以幫助我查看代碼並指出我的錯誤。感謝大家。ImageButton不能在Tab更新面板上工作

嗨。 @ Asif.Ali謝謝你的回覆。刪除'UpdateMode ='Conditional''後，當我按下添加按鈕時，它將顯示來自其他選項卡的內容與當前選項卡中的內容，並且保存按鈕仍然無法工作。我也用'
所以嘗試手動觸發保存按鈕。 – AsifAli72090
嗨。 @ Asif.Ali感謝您的回覆。手動觸發與我之前評論中提到的相同嗎？如果相同，則不起作用。 –
