Question

问题是apply和ok按钮不起作用。

好吧，我有一些继承EditorPart且已覆盖CreateChildControls，ApplyChanges和SyncChanges方法的网站部分。好吧，当加载控件时，调用SyncChanges方法。在调用CreateChildControls之后。在我尝试通过点击apply和/或ok按钮保存更改之前，一切都很顺利。点击后，系统会调用CreateChildControls，但不会调用ApplyChanges，也不会调用SyncChanges。

好吧，我不知道如何解决这个问题。请，建议。

嗯，问题出在儿童网站上。它有GridView DropDownLists与AutoPostBack=true导致回发，并且在任何回发外部按钮不起作用之后。所以我用JS-jQuery重写了内部webpart，它运行正常。
