collectionviewsource

It appears that filtering an ObservableCollection with CollectionViewSource is not possible in WinRT : See here! I can filter using LINQ , but how do I get the UI to update if changes that affect the filtered data are made? I ended up writing my own class to achieve the desired effect: public class ObservableCollectionView<T> : ObservableCollection<T> { private ObservableCollection<T> _view; private Predicate<T> _filter; public ObservableCollectionView(IComparer<T> comparer) : base(comparer) { } public ObservableCollectionView(IComparer<T> comparer, IEnumerable<T> collection) : base(comparer,

I want to know how I can refresh a CollectionViewSource when a button is clicked? So far I have <Window.Resources> <CollectionViewSource x:Key="cvsCustomers" Source="{Binding CustomerCollection}" Filter="CollectionViewSource_Filter" > </CollectionViewSource> </Window.Resources> Which creates the CollectionViewSource... <DataGrid HorizontalAlignment="Left" Height="210" Margin="47,153,0,0" VerticalAlignment="Top" Width="410" ItemsSource="{Binding Source={StaticResource cvsCustomers}}" CanUserAddRows="False" Which binds the source to my Datagrid private void CollectionViewSource_Filter(object

Ok, so this question is related to Windows Phone 7/Silverlight (updated WP7 Tools, Sept 2010), specifically filtering an underlying ObservableCollection<T> . In mucking about with the WP7 template Pivot control application, I've run into an issue whereby changing an underlying item in an ObservableCollection<T> , does not result in the on-screen ListBox being updated. Basically, the sample app has two pivots, the first directly bound to the underlying ObservableCollection<T> , and the second bound to a CollectionViewSource (i.e., representing a filtered view on the underlying

I have a datatemplate for a viewmodel where an itemscontrol is bound against a CollectionViewSource (to enable sorting in xaml). <DataTemplate x:Key="equipmentDataTemplate"> <Viewbox> <Viewbox.Resources> <CollectionViewSource x:Key="viewSource" Source="{Binding Modules}"> <CollectionViewSource.SortDescriptions> <scm:SortDescription PropertyName="ID" Direction="Ascending"/> </CollectionViewSource.SortDescriptions> </CollectionViewSource> </Viewbox.Resources> <ItemsControl ItemsSource="{Binding Source={StaticResource viewSource}}" Height="{DynamicResource equipmentHeight}" ItemTemplate="

I'm using a DataGrid bound to a CollectionViewSource ( players ), itself bound to the currently selected item of a ListBox ( levels ), each item containing a collection to be sorted/displayed in the DataGrid: <ListBox Name="lstLevel" DisplayMemberPath="Name" IsSynchronizedWithCurrentItem="True" /> ... <!-- DataGrid source, as a CollectionViewSource to allow for sorting and/or filtering --> <CollectionViewSource x:Key="Players" Source="{Binding ElementName=lstLevel, Path=SelectedItem.Players}"> <CollectionViewSource.SortDescriptions> <scm:SortDescription PropertyName="Name" /> <

I have a bunch of combos that all share the same available choices. These choices are provided in a collection exposed from my ViewModel. All fine and dandy. I now want these choices sorted, so I decided to expose an ICollectionView from my ViewModel instead of my usual ReadonlyObservableCollection<T> , and sort the collection view in my ViewModel. class EditStuffViewModel : ViewModelBase { public EditStuffViewModel (ObservableCollection<Choice> choices) { Choices = new CollectionViewSource() { Source = choices }.View; Choices.SortDescriptions.Add(new SortDescription("Name", ListSortDirection
