推荐答案

您不知道.您要做的是通过查询字符串或会话将所选值传递到新页面.然后，您可以在新页面中重建下拉列表项并设置所选项.如果您绝对必须通过组成下拉列表项的整个集合，那么您也可以随时将其放入会话中.

You don''t. What you do is pass the selected value to the new page either by querystring or session. Then you rebuild the dropdownlist items in the new page and set the selected item. If you absolutely have to pass the entire collection that makes up the dropdownlist items, then you could always throw them in the session too.
