Does anybody know if it is possible to do databinding on an IValueConverter based class? I have the following converter: [ValueConversion(typeof(int), typeof(Article))] public class LookupArticleConverter : FrameworkElement, IValueConverter { public static readonly DependencyProperty ArticlesProperty = DependencyProperty.Register("...
Hi girls and guys! I am currently working on a little localization framework for WPF (don't even think about pointing me to locBAML...) and wondered if it was possible to find out the containing assembly of a specified DependencyObject. For example: I have a normal window definition in XAML in the file Window1.xaml. The window contains...
Hi All, I'm getting this error: Cannot use a DependencyObject that belongs to a different thread than its parent Freezable What does that even mean? Is it in English? Is the parent frozen, or is it just freezable? Any way to make a parent not freezable, if it makes the error go away? What's happening: I have two opengl winforms ...

In XAML I would like to use markup like thi...

I created a ComboBox subclass and added my functionality. Now I want to expose external properties of the TextBox for example: <a:MyComboBox SpellCheck.IsEnabled="True" TextBox.SelectedText="{Binding X}" /> Is this possible, I maybe didn't choose the wrong particular property but I guess you understand what I mean. Is this possible?...
Thus far, Microsoft's C# team has resisted adding formal compile-time macro capabilities to the language. There are aspects of programming with WPF that seem (to me, at least) to be creating some compelling use cases for macros. Dependency properties, for instance. It would be so nice to just be able to do something like this: [Depen...
As of Silverlight 4 it is possible to data bind against a DependencyObject (instead of a Framework element in previous versions). So far so good, but how do I bind agains a collection of DependencyObjects. The DataContext is not passed from the ObservableCollection to the collection elements, so that the DependencyProperties of the Depe...

I have read that SL4 introduces the ability to data bind properties on objects that derive from DependencyObjects, where previously data-binding only worked on FrameworkElements or FrameworkContentElements. However, I am not clear on how the binding source is determined when binding properties of DependencyObjects. In the case of Frame...
