没有理由使用 ContentControl 中的页面。 页面是 UserControl 类的子类，它增加了对在 Frame中使用的支持。 控件以支持导航，后退堆栈/历史记录等。您可能应该将 Page 替换为 UserControl 在XAML中以及后面的代码，因此您最终会得到这样的东西：

There is no reason to use a Page within a ContentControl. A Page is a subclass of the UserControl class that adds support for being used within a Frame control to support navigation, back stack/history, etc. You should probably replace Page with UserControl in XAML and code behind, so you would end up with something like this:

<UserControl x:Class="ExampleApp.myControl2">
    <Grid x:Name="Content" Height="651" Width="941" Background="White">
        ...
        ...
    </Grid>
</UserControl>

您可以将 UserControl 本身放在 DataTemplate 如果要在 ContentControl $ c $中用作 DataTemplate c>：

You can put the UserControl itself in a DataTemplate if you want to use it as a DataTemplate in a ContentControl:

<ContentControl
    xmlns:controls="using:ExampleApp">
    <ContentControl.Resources>
        <DataTemplate
            x:Key="Test">
            <controls:myControl2 />
        </DataTemplate>
    </ContentControl.Resources>
</ContentControl>
