Question

在我正在开发的网站上，我有一个（现在）2页，每页有2个日历控件，显示课程日期，一个用于初学者课程，一个用于高级课程。

当最初导航到page1时，控件正常工作（点击时）。

但是当导航到第2页时，控件（点击时）要么不工作，要么实际导航回第1页。

就好像日历控件被缓存或类似的东西，只记得它在网站上首次使用的位置。

我也试过禁用页面上的所有缓存都无济于事。

我不想使用javascript日历弹出窗口，因为你必须单击一个按钮才能显示它。

Answer 1

控件通常不会在任何地方重定向。很可能您在click事件中有一个执行该重定向的代码。要解决问题，请在第2页上删除该代码，看看它是否仍然重定向。如果，假设控件被“缓存”，他们应该继续重定向而不需要代码。如果页面行为不同（没有代码没有重定向） - 再次启用代码并逐行检查。可以是您在会话中保留第1页上的日期，在第2页上，您再次检查该会话，然后重定向。

ASP.NET在多个页面上的行为不正确
