WinRT 8.1 Phone - ListView reordering

Question

I need to create a reorderable ListView in a Windows Phone 8.1 app created using WinRT. The XAML is the following (it binds to an ObservableDictionary in the codebehind):

Answer 1

It appears that the property CanReorderItems is not supported on Windows Phone 8.1.

(I tried a simple example, and it does not work, and I could not find any combination that made it work as it does on Windows 8.1.)

Answer 2

For WP you need to set ListViewBase.ReorderMode

This is what works for me - no idea which properties are really necessary; ReorderMode is set in code behind:

<ListView x:Name="fooListView"
          ItemsSource="{Binding barlist, Mode=OneWay}" 
          SelectionMode="None"                
          AllowDrop="True" CanDragItems="True" IsSwipeEnabled="True" />

The ListViewBase.Reorder property is available only for Windows Phone, so if you have the XAML in a Shared part of a universal app, you need to set it using conditional compile like so:

#if WINDOWS_PHONE_APP
            MainListView.ReorderMode =  ListViewReorderMode.Enabled;
#endif
