在 Widonws Phone 7 上点击后退按钮后刷新页面
我正在开发一个 Windows Phone 应用程序。这是某种可以具有自定义提醒类别的提醒。我正在使用 mvvm 模式。
我有两页。一种用于输入新数据（类别名称和描述）并进行编辑，另一种用于选择特定类别，然后可以对其进行编辑/删除。
第二页有一个列表框，显示所有存在的类别...单击其中一个类别后，第一页的值（类别名称和描述）已输入到文本框中。我现在可以编辑并保存它们。除了一件事之外，所有这些都工作正常。保存并点击后退按钮（以便我可以返回列表）后，我意识到页面没有刷新，因此仍然显示旧值。如何让页面再次弹出后“刷新”...
I am developing a windows phone application. It's some kind of reminder which can have custom reminder categories. I am using the mvvm pattern.
I have two pages. One is for entering new data (category name and description) and editing and the other is for selecting a specific category wchich can then be edited/deleted.
The second page has a listbox which displays all categories that exist... after clicking on one of them the first page where the values (category name and description) are already entered in the textboxes. I can now edit and save them. All this works fine except for one thing. After saving and hitting the back button (so that i can get back to the list) i realize that the page isnt refreshing so that the old value is still displayed. How can i make the page "refresh" after poping up again...
