FlipView problem

Question

Hi,

I am creating win 8.1 store app.

If I use flip view to show profiles it causes an error.

Here is a flip view code.

<FlipView VerticalAlignment="Bottom"  x:Name="profileFlipView" Grid.Row="1"  ItemsSource="{Binding Profiles}" >
<FlipView.ItemsPanel>
		<ItemsPanelTemplate>
			<StackPanel Orientation="Horizontal" Margin="0,0,30,40" />
		</ItemsPanelTemplate>
	</FlipView.ItemsPanel>
	<FlipView.ItemTemplate>
		<DataTemplate>
			<TextBlock Text="{Binding Name}" Margin="5,0,5,0" Style="{StaticResource HeaderTextBlockStyle}" />
		</DataTemplate>
	</FlipView.ItemTemplate>
</FlipView> 

Item source is binded to Profiles collection, however when I leave current page, modify source collection and then go back to page with FlipView, its not updated and if I do it again, it throws an exception.

{"Error HRESULT E_FAIL has been returned from a call to a COM component."}

Error code: -2147467259

Stack trace:

   at System.Collections.Specialized.NotifyCollectionChangedEventHandler.Invoke(Object sender, NotifyCollectionChangedEventArgs e)
   at System.Collections.ObjectModel.ObservableCollection`1.OnCollectionChanged(NotifyCollectionChangedEventArgs e)
   at System.Collections.ObjectModel.ObservableCollection`1.InsertItem(Int32 index, T item)
   at System.Collections.ObjectModel.Collection`1.Add(T item)

It seems like there is a subscribed event handler from first FlipView.

Answer 1

The problem is unlikely to be in the Xaml. What does the code behind look like? Where exactly is the error?

Can you share a minimal sample which demonstrates the problem on your SkyDrive?

I am unable to demonstrate the problem on minimal sample. However when I set Width and Height properties it works.
