Panel's Children作为ComboBox的ItemsSource

Question

在WPF中，我可以使用Panel的Children集合作为ComboBox的ItemsSource：

WPF Panel's Children as ComboBox's ItemsSource

但在UWP中，这会抛出异常：＆＃34;参数不正确。＆＃34; ＆安培; vbCrLf

Code-XAML：

<StackPanel>

<StackPanel Name="Panel1">

<TextBox Text="Item 1" />

<TextBox Text="Item 2" Margin="0,10,0,0" />

</StackPanel>

<ComboBox Margin="0,10,0,0" Name="Combo1" >
<ComboBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Text}" />
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>

</StackPanel>

守则背后：

Private Sub MainWindow_Loaded(sender As Object, e As RoutedEventArgs) Handles Me.Loaded

Combo1.ItemsSource = Panel1.Children

End Sub

我如何在UWP实现同样的目标？
