在 Web 应用程序上保持位置
本文关键字：位置 程序上 应用程序 Web 应用 | 更新日期: 2023-09-27 17:55:23
我希望我已经在这方面做了功课。我有一个相当大的 Web 应用程序，当按下按钮时，网页会在回发时跳到页面顶部。我知道该页面需要行MaintainScrollPositionOnPostback="true"
所以我回到了第一原则，建立了两个网页。一个有一个 ajax 控件 tookit 选项卡容器，第二个没有。
在带有选项卡容器的那个上，维护位置属性没有影响，页面跳回到选项卡容器。在没有 ajax 的那个上，它可以正常工作。两个页面都在下面。
你能告诉我为什么以及如何解决这个问题吗？
