我有一個擁有單個UpdatePanel的UserControl的單個實例的頁面。 UpdatePanel內部有幾個Button控件。這些控件的Click事件在UserControl的Init事件中的代碼隱藏中被連接起來。在UpdatePanel中第一次部分回發後丟失Button.Click事件
我得到的第一個按鈕,我推,每次沒有問題的Click事件。之後,我只獲得一個按鈕的Click事件(SearchButton) - 其餘的都被忽略。我已經包含了下面的控件的代碼 - 爲簡潔起見,我已經排除了點擊事件處理方法,但他們都是標準的「無效Button_Click(對象發件人,EventArgs的)」的品種。有任何想法嗎?

這是我的情況。如果您設置動態添加控件的ID,以確保它們是相同的每一次,它固定它 – 2013-09-18 15:24:16
