copied!<p>I'd be grateful if someone could give me some pointers on a very annoying problem I'm having - I'm going crazy trying to make this work as I'm sure there must be a simple solution but I can't see it!</p> <p>As a result of the very helpful answers to my previous question posted on here, I'm attempting to use the MVVM approach in WPF. </p> <p>I've got a listview in one page that binds to an ObservableCollection in the viewmodel & the listview's selected item is bound to a property called SelectedEntity in the viewmodel:</p> <pre><code><Listview Name="listview" ItemsSource="{Binding Entities}" SelectedItem="{Binding SelectedEntity, Mode=TwoWay}"> </code></pre> <p>In a different page I have a textbox bound to the Name property of SelectedEntity in the viewmodel:</p> <pre><code><TextBlock Text="{Binding Path=SelectedEntity.Name}" /> </code></pre> <p>The code in the viewmodel is:</p> <pre><code>Private Entity selectedEntity; Public Entity SelectedEntity { get { return selectedEntity; } set { if (selectedEntity != value) { selectedEntity = value; RaisePropertyChanged("SelectedEntity"); } } </code></pre> <p>RaisePropertyChanged is a method that implements INotifyPropertyChanged.</p> <p>What I want to do is have the textblock update when the currently selected item in the listview changes but it just won't? Am I missing something really obvious?</p> <p>Thanks very much for any guidance you can give me!</p>
