由 ☆樱花仙子☆ 提交于 2019-12-18 10:35:32

We've thought about using UpdatePanel for this. However, we don't like the fact that the UpdatePanel is sending the whole page back to the server. 回答1: Don't move to UpdatePanels. After coming from jQuery, the drop in performance would be untenable. Especially on a page as complex as yours sounds. If you have 2,000
