Binding a CollectionViewSource to ObservableCollection
.net, binding, collectionviewsource
Solution
It will work this way:
<ListBox ItemsSource="{Binding}">
<ListBox.DataContext>
<CollectionViewSource Source="{Binding Path=DocProps1}">
</CollectionViewSource>
</ListBox.DataContext>
</ListBox>
This article XAML Binding to a CollectionViewSource property on a ViewModel has some explanations of this behaviour
Problem
Cannot bind the CollectionViewSource DocProps is a public property ``` public ObservableCollection<DocProp> DocProps1 ``` DataContext is self ``` DataContext="{Binding RelativeSource={RelativeSource self}}" ``` This works ``` <ListBox Grid.Row="0" Grid.Column="0" ItemsSource="{Binding Path=DocProps1}"> ``` I cannot wire up a CollectionViewSource to sort This does not even get DocProps1 ``` <ListBox Grid.Row="0" Grid.Column="0"> <ListBox.ItemsSource> <Binding> <Binding.Source> <CollectionViewSource Source="{Binding Path=DocProps1}"> <CollectionViewSource.SortDescriptions> <scm:SortDescription PropertyName="Name" /> </CollectionViewSource.SortDescriptions> </CollectionViewSource> </Binding.Source> </Binding> </ListBox.ItemsSource> ``` How do I bind a CollectionViewSource to a public property? Thanks
