清除控件在modalpopupetentender

Question

我有一個帶有超鏈接的GridView，並在超鏈接上點擊一個Modal Popup Extender彈出。有些文本框是基於GridView被點擊的行顯示或隱藏的。我的問題是當Modal彈出窗口和用戶填寫了texbox並讓他們說關閉時，我們隱藏Modal Popup Extender，當他們點擊不同的GridView行或者之前的數據出現在同一行上時。似乎Modal Popup Extender不會清除它下面的控件。我試着將UpdatePanel設置爲條件並強制更新不起作用。請幫助我一直試圖解決這個問題，現在幾天，它變得非常討厭。謝謝你的幫助。

Answer 1

嘗試從代碼隱藏調用modalpopupextender：

ModalPopupExtender1.Show(); 

Answer 2

使用了LinkBut​​ton，而不是和點擊清除在modalpopup控件，然後調用ModalPopup.Show（）
