刷新Windows Phone 8页 [英] Refreshing a windows phone 8 page

问题描述

我想让我的应用用户手动刷新页面。为此，我在应用栏中添加了一个刷新按钮，我在按钮后面写了以下代码...

I want to enable users of my app to manually refresh a page. For this i have included a refresh button in app bar and i have written the following code behind the button...

  NavigationService.Navigate（new Uri（" /MainPage.xaml） ？Refresh = true"，UriKind.Relative））;

 NavigationService.Navigate(new Uri("/MainPage.xaml?Refresh=true", UriKind.Relative));

但页面只是第一次刷新。当我第二次点击按钮没有任何反应...

but  the page refreshes only for the first time. When i click the button for the second time nothing happens...

任何解决方案？

提前致谢!!

推荐答案

嗨meesun，

Hi meesun,

Windows Phone似乎忽略了Refresh或甚至Cache设置。我认为这是因为节省电池。但这很容易规避。而不是附加"？Refresh = true"而不是只需附加一个这样的数字：

Windows Phone seems to ignore the Refresh or even the Cache settings. I think this is due to save battery. But it is easy to circumvent. Instead of appending "?Refresh=true" just append a number like this:

    NavigationService.Navigate（new Uri（" /MainPage.xaml？" + DateTime.Now.Ticks，UriKind.Relative））;

    NavigationService.Navigate( new Uri("/MainPage.xaml?" + DateTime.Now.Ticks, UriKind.Relative) );
