我使用Denis Bauer的DynamicControlsPlaceholder在回發後保存動態控件的視圖狀態。 我之前在我的項目的一個早期部分使用了DynamicControlsPlaceholder，它的工作完美無瑕。回發後使用JuiceUI滑塊控制問題
但是，今天我遇到了困難。我創建了一個頁面，其中有許多文本標籤，滑動條和文本框（由數據庫中有多少元素定義），如下所示。滑桿是JuiceUI滑塊控件，文本框是普通的ASP.NET文本框。
回發文本標籤（字面控制）和餅圖消失後，將文本框減小尺寸（文字內保持）和sliderbars被複位爲最低值，而無需移動滑塊（能力滑塊根本無法移動）。
我很新的ASP.NET和我完全難倒，爲什麼發生這種情況。你認爲這是動態控制佔位符，JuiceUI滑塊或我的代碼（見下文）的問題？
