我所創建的時隙....DropDownList的OnSelectedIndexChanged事件在不觸發
它基本上是引導代碼......，我想在.net中執行它爲我的項目的目的....
我已經在我的項目中使用的一些DropDownLists ....他們的活動沒有工作.....
這說明什麼執行後...
我的代碼如下... 。

的活動沒有工作..........
任何解決方案，請.......... .....！
還有一個問題是要添加一個或多個天到文本框的日期？
當我設置AutoPostback = True，它的工作原理，但它不會停留在當前步驟，它會進入第1步.... – THOR
@ THOR讓我更新答案。 –
@THOR請在下拉列表中查看屬性AutoPostback。所有具有onselectedIndexChanged的ddl都需要這個屬性，沒有這個事件永遠不會被觸發。 –
