Question

单击列表框项目时是否可以移动到下一个全景项目页面？

我在下面尝试了这个，但它给了我一个只读错误

编辑：我已经想出如何实现这一目标，但它设置的背景图像与第一个项目中显示的相同，是否有人知道解决此问题的方法？

private void myListBox_Tap(object sender, GestureEventArgs e)
 {
      pano.SelectedItem = 1;
 }

PanoramaPage1.xaml

<!--LayoutRoot contains the root grid where all other page content is placed-->
<Grid x:Name="LayoutRoot">

    <controls:Panorama Name="pano" Title="Trending Now" ItemsSource="{Binding}" FontSize="12">

        <!--Assigns a background image to the Panorama control.-->
        <controls:Panorama.Background>
            <ImageBrush ImageSource="/TrendApp;component/Images/pan.png" />
        </controls:Panorama.Background>
        <controls:Panorama.TitleTemplate>
        <DataTemplate>
                    <TextBlock Text="{Binding Content, RelativeSource={RelativeSource TemplatedParent}}" FontSize="100" Margin="0,50,0,0" />

                    </ListBox.ItemTemplate>
                </ListBox>

            </Grid>

        <controls:PanoramaItem Name="item2" Header="" FontSize="10">

            <Grid/>
        </controls:PanoramaItem>
        <!--Panorama item three.-->
        <controls:PanoramaItem Header="Search">
            <Grid>
                <TextBox Height="75" HorizontalAlignment="Left" Margin="96,12,0,0" Name="textBox1" Text="Search" VerticalAlignment="Top" Width="235" />
            </Grid>
        </controls:PanoramaItem>
    </controls:Panorama>
</Grid>

感谢您的帮助

Answer 1

找到我的答案here

我需要MyPanorama.DefaultItem = MyPanorama.Items[1];

Answer 2

抱歉，SelectedIndex和SelectedItem是只读的。我所知道的唯一解决方法是设置DefaultItem，如下所示：

pano.DefaultItem = myPanoramaItem;

以编程方式移动到列表框上的下一个全景项目
