So you have to be careful and balance the use of data binding. 2.Stronger readability – depends if you are … Read more
There is a much easier way! You can easily create an attached DocumentXaml (or DocumentRTF) property which will allow you to bind the RichTextBox‘s document. It is used like this, where Autobiography is a string property in your data model: <TextBox Text=”{Binding FirstName}” /> <TextBox Text=”{Binding LastName}” /> <RichTextBox local:RichTextBoxHelper.DocumentXaml=”{Binding Autobiography}” /> Voila! Fully bindable … Read more
You always bind to an ICollectionView, whether you make it explicit or not. Assume that we have var collection = new ObservableCollection<string>(); var collectionView = CollectionViewSource.GetDefaultView(collection); In this case, binding to collection or to collectionView is one and the same: the binding engine will bind to the default collection view (which is reference equal to … Read more

Well, if the DataContext is already set you could cast it and call the command: var viewModel = (MyViewModel)DataContext; if (viewModel.MyCommand.CanExecute(null)) viewModel.MyCommand.Execute(null); (Change parameter as needed)
You must make your binding bidirectional : <checkbox IsChecked=”{Binding Path=MyProperty, Mode=TwoWay}”/>
Some research results for OneWayToSource… Option # 1. // Control definition public partial class FlagThingy : UserControl { public static readonly DependencyProperty IsModifiedProperty = DependencyProperty.Register(“IsModified”, typeof(bool), typeof(FlagThingy), new PropertyMetadata()); } <controls:FlagThingy x:Name=”_flagThingy” /> // Binding Code Binding binding = new Binding(); binding.Path = new PropertyPath(“FlagIsModified”); binding.ElementName = “container”; binding.Mode = BindingMode.OneWayToSource; _flagThingy.SetBinding(FlagThingy.IsModifiedProperty, binding); Option # … Read more
The problem is that WebBrowser.Source is not a DependencyProperty. One workaround would be to use some AttachedProperty magic to enable this ability. public static class WebBrowserUtility { public static readonly DependencyProperty BindableSourceProperty = DependencyProperty.RegisterAttached(“BindableSource”, typeof(string), typeof(WebBrowserUtility), new UIPropertyMetadata(null, BindableSourcePropertyChanged)); public static string GetBindableSource(DependencyObject obj) { return (string) obj.GetValue(BindableSourceProperty); } public static void SetBindableSource(DependencyObject obj, string … Read more
Another approach that might work for you is to create a custom IValueConverter that takes a method name as a parameter, so that it would be used like this: ItemsSource=”{Binding Converter={StaticResource MethodToValueConverter}, ConverterParameter=”GetChildren”}” This converter would find and invoke the method using reflection. This requires the method to not have any arguments. Here’s an example … Read more
