ScrollIntoView（）在WinRT（C＃xaml）应用程序中不起作用

Question

我对ScrollIntoView ...

有疑问

上次我使用这种方法并且一切正常。但现在我遇到了问题，我不知道为什么。

我认为我看了90％的互联网关于这个主题，我没有发现它......

这是我的XAML：

<Grid Grid.Row="1" >
    <ListView 
        x:Name="NameOfList" 
        HorizontalAlignment="Stretch" 
        IsZoomedInView="False"
        ItemsSource="{Binding someSource}"
        ItemTemplate="{StaticResource someTemplate}"
        IsItemClickEnabled="True"
        someNamespace:ItemClickedToCommand.Command="{Binding someCommand}"
        SelectedItem="{Binding someSelecteditem, Mode=TwoWay}"
        SelectedIndex="{Binding someselectedindex, Mode=TwoWay}"
        ItemContainerStyle="{StaticResource someContainerStyle}"
        >
    </ListView>
</Grid>

这是我的代码隐藏：

var page = GetPage();
var someGrid = page.FindName("SomeGridUserControlGrid") as Grid;
var someUserControl = someGrid.FindName("someUserControl") as SomeUserControl;

ListView listViewSome = someUserControl.FindName("SomeListView") as ListView;

// listViewSome is not null, this object has correct value
//but code below doesn’t work…
listViewSome.SelectedItem = someSelecteditem;
listViewSome.ScrollIntoView(listViewSome.SelectedItem);
