Is there a way to detect that ScrollViwer of ListView is in scrolling mode and stopped scrolling. In windows phone 8.1 ListView we can not get reference of the scrollviewer. Any one done it in windows phone 8.1 WinRT app? yasen Once the ListView is Loaded you can get the ScrollViewer like this: var sv = (ScrollViewer)VisualTreeHelper.GetChild(VisualTreeHelper.GetChild(this.ListV, 0), 0); Edit As Romasz suggested, once you get the ScrollViewer , you can use its ViewChanged event, to monitor when it is scrolling and when it stops. Also, here's the generic extension method that I use for

This is a common situation in XAML based apps (WPF/Silverlight/WinRT). WPF related link -> WPF Databinding: How do I access the "parent" data context? RelativeSource with AncestorType , and Mode=FindAncestor usually comes to rescue in WPF. Both of these are missing in WinRT API. How to access the Parent's (may not be immediate one), DataContext ? (I am aware of TemplateBinding , and ElementBinding but both are not suitable mostly in DataTemplate). LMK I just had the same problem. Presumably this is common?? Here is a crude solution that works: Bind the Tag property of a top level element to

I have this XAML to display a ListView in a C++/CX code. The ListView will be used as a selection menu. <ListView x:Name="itemsListView" ItemsSource="{Binding Source={StaticResource MenuDataSourceCVS}}" HorizontalAlignment="Stretch" Width="230" Margin="0,45,0,0" VerticalAlignment="Top" Grid.Row="1" SelectionChanged="itemsListView_SelectionChanged" SelectionMode="Single" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" FontFamily="Global User Interface"> <ListView.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal" Height="40" Width="230"> <TextBlock Text="

does anybody know what the "new way" of FindAncestor in XAML bindings is? Looking at the RelativeSourceMode ( http://msdn.microsoft.com/en-us/library/windows/apps/windows.ui.xaml.data.relativesourcemode ) there are only options left for referencing self or the TemplatedParent. FindAncestor is gone. I'd like to know why and what are the typical solutions to the problems I fixed using FindAncestor. Best regards Gope Why it's missing? No idea, but I doubt there's an explanation other than "Microsoft did not have enough time to implement all the features in time". An easy work-around is to use

How can I get DesignTime data in WinRT XAML so the designer shows sample data? Simple enough. Create a Model like this: public class Fruit { public string Name { get; set; } } Create a base ViewModel like this: public class BaseViewModel { public ObservableCollection<Fruit> Fruits { get; set; } } Create a real ViewModel like this: public class RealViewModel : BaseViewModel { public RealViewModel() { if (!Windows.ApplicationModel.DesignMode.DesignModeEnabled) LoadData(); } public void LoadData() { // TODO: load from service } } Create a fake-data ViewModel like this: public class FakeViewModel

How do I take an object and convert it to a JSON string and then back into that object from a string, specifically, in WinRT for my Windows 8 Metro application? Like this: using System.IO; using System.Runtime.Serialization.Json; using System.Text; public static T Deserialize<T>(string json) { var _Bytes = Encoding.Unicode.GetBytes(json); using (MemoryStream _Stream = new MemoryStream(_Bytes)) { var _Serializer = new DataContractJsonSerializer(typeof(T)); return (T)_Serializer.ReadObject(_Stream); } } public static string Serialize(object instance) { using (MemoryStream _Stream = new
