在以display：none

Question

我在asp：panel中有一个Ajax ComboBox。面板上分配了我的CssClass =“ hide”，其中包括“ display：none”。

用户可以单击触发JavaScript函数的另一个元素，该元素将在CssClass =“ hide”和CssClass =“ show”之间切换面板（“ show”包括“ width：100％”，这会导致面板中的所有控件在组合框上显示箭头图像除外

如果我将面板设置为以CssClass =“ show”开始生活，则所有显示正确。然后，我可以使用该函数将其更改为CssClass =“ hide”，然后再更改回CssClass =“ show”，一切看起来仍然正确！

感谢您的帮助。
