To learn data binding I have a window with just 3 controls: 1. Previous Button 2. TextBox 3. Next button My goal is to bind a collection of names to the TextBox and be able to cyle through them with the two navigation buttons. Here's the code I have in place for the XAML window------------------------------------ private ListCollectionView view; public DataNavigator() { InitializeComponent(); ICollection<string> names = new Data().GetJustNames(); DataContext = names; view = (ListCollectionView) CollectionViewSource.GetDefaultView(DataContext); view.CurrentChanged += view_CurrentChanged; } void view_CurrentChanged(object sender, System.EventArgs e) { btnPrevious.IsEnabled = (view.CurrentPosition > 0); btnNext.IsEnabled = (view.CurrentPosition < view.Count-1); } private void btnNext_Click(object sender, RoutedEventArgs e) { view.MoveCurrentToNext(); } private void btnPrevious_Click(object sender, RoutedEventArgs e) { view.MoveCurrentToPrevious(); } --------------------------------------------------------------------------------------------- Now I'm pretty sure the navigation is working because the buttons become disabled correctly. My only question is how do I set the binding to the TextBox.Text property in XAML? <TextBox Margin="139,56.5,169,65.5" Name="tbName" Text="{Binding Path=?}"/> I'm not sure what the Path should be. I don't think I have to set the source because the TextBox is within the DataContext right? Thanks for any insight you might be able to provide! |
