I have a Windows phone 8.1 application where I have two pages displaying data. The first page has a listview displaying all of the data from an sqlite database, and when the user taps on one item in the listview, the second page opens with a listview that contains more details about that specific record from the database. My question is how to achieve this in Windows Phone 8.1 using c# ?
推荐答案
在第一页,你应该这样写:
On first page you should write something like this:
Frame.Navigate(typeof(SecondPage), someData);
有关第二页,你应该覆盖的OnNavigatedTo(NavigationEventArgs E)。
例如:
For second page you should override OnNavigatedTo( NavigationEventArgs e ). For example:
protected override void OnNavigatedTo( NavigationEventArgs e )
{
MyData data = e.Parameter as MyData.
}
