用户控件绑定列表到 flipview？

Question

我打算实现用户控件的水平列表，我想在运行期间将其添加到翻转视图中，我尝试了以下代码：

<FlipView Grid.Row="2" Name="SlideFlipView"
              ItemsSource="{x:Bind SlideViews}"
              SelectionChanged="SlideFlipView_SelectionChanged"
              Background="AliceBlue">
        <FlipView.ItemTemplate>
            <DataTemplate>
                <Frame Name="MenuDetailFrame" SourcePageType="{Binding}"/>
            </DataTemplate>
        </FlipView.ItemTemplate>
</FlipView>

Class 看起来像下面的代码：

 public sealed partial class MenuDetailPage : Page
 {
    private List<object> SlideViews;

    public MenuDetailPage()
    {
        this.InitializeComponent();
        LoadInitials();
    }

    private void LoadInitials()
    {
        SlideViews = new List<object>
        {
            typeof(TopImageBottomTextControl),
            typeof(TopTextBottomImageControl)
        };
    }
 }

但是当我运行程序时，用户控件没有出现在翻盖中。如果我在这里遗漏了什么，请告诉我

Answer 1

根据 "Frame Class":

SourcePageType can be set in XAML, using string-to-type conversion that's interpreted using XAML namespace mappings, but that's rarely done. It's a better practice to have code at the app level that tracks activation and whether a suspended app is resuming, which then uses Frame.Navigate to set the current page.

根据您的要求，您可以将用户控件对象绑定到框架的 Content。

private void LoadInitials()
{
    SlideViews = new List<object>
 {
    new TopImageBottomTextControl(),
    new TopImageBottomTextControl()
 };
}

用法

<FlipView Name="SlideFlipView"
          ItemsSource="{x:Bind SlideViews}"
          SelectionChanged="SlideFlipView_SelectionChanged"
          Background="AliceBlue">
    <FlipView.ItemTemplate>
        <DataTemplate>
            <Frame Name="MenuDetailFram"  Content="{Binding}" />
        </DataTemplate>
    </FlipView.ItemTemplate>
</FlipView>

Answer 2

以下没有数据模板的代码对我有用：

<FlipView Grid.Row="2" 
          Name="SlideFlipView" 
          ItemsSource="{x:Bind SlideViews}"
          SelectionChanged="SlideFlipView_SelectionChanged"
          Background="AliceBlue">
</FlipView>

Class 中 slideviews 对象的初始化看起来像

private void LoadInitials()
{
  SlideViews = new List<object>
  {
    new UserControl1(),
    new UserControl2()
  };
}
