问题 I am trying to implement some combo box sorting using CollectionViewSource. This combo box is actually part of a data template and is repeated in a list view. My first approach seemed to work (using CollectionViewSource) but all my combo boxes shared the same data context. This made it so whenever one of the other boxes was changed all the others changed to reflect - not a desired side effect. I decided to just pull back and try to implement a basic combo box (not inside a data template)

How to automatically update filter and/or sort order on CollectionViewSource, when an individual item's property changes?

问题 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

I have a ListView which I'm binding to a CollectionViewSource in code behind with: collectionView = CollectionViewSource.GetDefaultView(TableView.ItemsSource); collectionView.SortDescriptions.Clear(); collectionView.SortDescriptions.Add(new SortDescription(propertyName, direction)); The TableView is the ListView, the propertyName is the name of the column I want sorted, and direction is either ascending or descending. The XAML has the following for ItemSource: ItemsSource="{Binding Rows}" The code behind has the following for the Rows: List<TableRow> rows; public List<TableRow> Rows { get {

问题 I am currently implementing the application that displays hierarchy using ListBoxes (please do not suggest using TreeView , ListBoxes are needed). It looks like that in the article: WPF’s CollectionViewSource (with source code). Classes: public class Mountains : ObservableCollection<Mountain> { public ObservableCollection<Lift> Lifts { get; } public string Name { get; } } public class Lift { public ObservableCollection<string> Runs { get; } } The example uses CollectionViewSource instances
