问题描述

protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
        {
            base.OnNavigatedTo(e);
            string parameter = this.NavigationContext.QueryString["parameter"];
			
			
			if (NavigationContext.QueryString.TryGetValue("parameter", out parameter))
			{
				 
				MessageBox.Show("Welcome To TestPage");
			}
        }

您好，我使用的是下面提供的xaml文件.我具有水平滚动列表.如果单击任何列表项，则应转到另一页并显示所选项目的详细信息.

Hi am using xaml file given below.i have horizontal scrolling list.if i clicked any list item it should go to another page and show selected item detail.

<StackPanel VerticalAlignment="Top" Width="Auto">
    <ListBox ItemsSource="{Binding Images}"  Width="Auto" ScrollViewer.VerticalScrollBarVisibility="Disabled" SelectionChanged="NotchsList11_SelectionChanged">
		 <ListBox.ItemsPanel>	<ItemsPanelTemplate>
						<StackPanel Orientation="Horizontal"  VerticalAlignment="Top">
						</StackPanel>
					</ItemsPanelTemplate>
		 </ListBox.ItemsPanel>
		<ListBox.ItemTemplate>
		<DataTemplate>
		<Border BorderBrush="White" BorderThickness="1,1,1,1" Margin="0,0,8,0">
		   <Image Source="{Binding}" Width="152" Height="90"  Stretch="Fill"  VerticalAlignment="Top"></Image>
			</Border>
				</DataTemplate>
					</ListBox.ItemTemplate>
						</ListBox>
 </StackPanel>

下面给出了我的mainpage.xaml.cs代码

My mainpage.xaml.cs code given below

private void NotchsList11_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
           try
            {
				NavigationService.Navigate(new Uri("/Test.xaml?parameter={0}",UriKind.Relative));
				//NavigationService.Navigate(new Uri("/Page1.xaml?parameter=test", UriKind.Relative));
			}
			catch(Exception)
			{
				MessageBox.Show("hi");
			}
        }

Page2.xaml.cs

Page2.xaml.cs

protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
        {
            base.OnNavigatedTo(e);
            string parameter = this.NavigationContext.QueryString["parameter"];
			
			
			if (NavigationContext.QueryString.TryGetValue("parameter", out parameter))
			{
				 
				
			}
        }
