彈出簡單的文本按鈕點擊

我有一個按鈕放置在我的GridView的每一行上。當用戶按下按鈕時，我想顯示一個簡單的彈出窗口，在其中顯示文本。部分文本是與特定行相關的DataKeyName。彈出簡單的文本按鈕點擊

我已經嘗試過用ModalPopupExtender myMPE由按鈕觸發和我使用的面板myPanel爲PopupControlID。問題在於TextBox txtPanel的面板在哪裏，我把DataKeyName的值始終是空的。我試圖調試沒有myMPE和麪板的txtPanel正確填寫。我想這會讓回帖混亂。

任何人都知道一個解決方案嗎？

您是否正在手動刷新模式彈出式面板上的UpdaePanel？如果沒有，請嘗試手動刷新updatePanel &將其updateMode設置爲有條件。檢查例如以上ASPX
