Question

我制作了显示某些事件的Windows Phone 8.1应用程序。它显示了事件的图片，标题，位置和ID。所有这些事件都显示在列表视图中。现在我想点击指定的事件并在新页面上显示事件的描述。任何人都知道如何检查列表视图中的哪个事件被点击并在新页面中显示他的描述（BlankPage1.xaml）？

我的班级

-FSfeed.cs

public class Rootobject
{
    public Class1[] Property1 { get; set; }
}

public class Class1
{
    public string id { get; set; }
    public string title { get; set; }
    public string description { get; set; }
    public string image { get; set; }
    public string start { get; set; }
    public string end { get; set; }
    public string location { get; set; }
}

在Listview中显示事件

-StartPage.xaml

            <Grid HorizontalAlignment="Left" Height="538" VerticalAlignment="Top" Width="400">
                <ListView x:Name="Reviews" Margin="0,0,0,0" Grid.Row="1" >
                    <ListView.ItemTemplate>
                        <DataTemplate>
                            <StackPanel Orientation="Horizontal">
                                <Border Background="{StaticResource ListViewItemPlaceholderBackgroundThemeBrush}" Width="110" Height="110">
                                    <Image Source="{Binding image}" Stretch="UniformToFill" />

                                </Border>
                                <TextBlock Text=" " />
                                <StackPanel x:Name="st1" Grid.Column="1" VerticalAlignment="Top" Orientation="Vertical" Margin="10,0,0,0" >
                                    <TextBlock Text="{Binding title}" TextWrapping="Wrap"/>
                                    <StackPanel Grid.Column="1" VerticalAlignment="Top" Orientation="Horizontal" Margin="0,0,0,0">
                                        <TextBlock Margin="10,0,0,0" Text="Location:" FontWeight="Bold"/>
                                        <TextBlock Margin="10,0,0,0" Text="{Binding location}"/>
                                    </StackPanel>
                                    <StackPanel Grid.Column="1" VerticalAlignment="Top" Orientation="Horizontal" Margin="0,0,0,0">
                                        <TextBlock Margin="10,0,0,0" Text="Start:" FontWeight="Bold"/>
                                        <TextBlock Margin="10,0,0,0" Text="{Binding start}"/>
                                    </StackPanel>
                                    <StackPanel Grid.Column="1" VerticalAlignment="Top" Orientation="Horizontal" Margin="0,0,0,0">
                                        <TextBlock Margin="10,0,0,0" Text="Id:" FontWeight="Bold"/>
                                        <TextBlock Margin="10,0,0,0" Text="{Binding id}"/>
                                    </StackPanel>
                                </StackPanel>
                            </StackPanel>
                        </DataTemplate>
                    </ListView.ItemTemplate>
                </ListView>
            </Grid>

在点击列表视图项目时将用户导航到新页面（BlankPage1）

-StartPage.xaml.cs

    private void Reviews_Tapped(object sender, TappedRoutedEventArgs e)
    {
        this.Frame.Navigate(typeof(BlankPage1));

        //check which event has been tapped and show his description on BlankPage1.xaml ?

    }

Answer 1

好的，我经过几个小时的研究后找到答案......

将以下代码添加到StartPage.xaml.cs

    private void Reviews_Tapped(object sender, TappedRoutedEventArgs e)
    {

        Class1 myobject = Reviews.SelectedItem as Class1;

        Frame.Navigate(typeof(BlankPage1), myobject);

    }

在目标页面上创建文本块（BlankPage1）并添加以下代码：

    protected override void OnNavigatedTo(NavigationEventArgs e)
    {
        var myObject = (Class1) e.Parameter;
        textblock.Text = myObject.title;
    }

Windows手机将所选参数从listview项目传递到其他页面
