How can a CanExecute of a commandBinding fire once the element has been removed from the visual tree?
I have a related question here where i have a user control with a command binding. The user control has being removed from the visual tree, yet the canExecute is still firing.

WPF - how do I extend (or work in parallel with) the built-in command mechanism?
Please excuse me if this is a dumb question - I have read a dozen articles on the WPF command infrastructure and I am more confused than ever.

Is it possible to have CommandManager requery only specific WPF command instead of all?
I'm trying to implement a highly responsive UI for my MVVM application, so I've chosen to have all command handlers automatically execute in a BackgroundWorker so they don't block the UI. But at the same time, I don't want the user to be able to execute the same command while it is still executing in the background. The solution seems o...

I have the following kind of layout: ContextMenu is set for each DataGridRow of DataGrid inside UserControl, which in its turn is inside DockableContent of AvalonDock.

How to intercept execution of a RoutedCommand within the view? (WPF / MVVM)
In a WPF / MVVM application, I am trying to find a code-efficient way to set the main view cursor to Cursors.Wait prior to any lengthy operation and to restore it to the default cursor after completion.

RoutedCommand.CanExecuteChanged event not consistently firing inside ElementHost
(Background: I'm porting a WinForms app to WPF in stages. At the present time, I still have a WinForms main form with an ElementHost that has WPF content in it.) I'd like my app to be told when certain ApplicationCommands such as Cut, Copy, and Paste change the value of their .CanExecute. I thought it'd be a simple matter of subscribing...

Find destination of a RoutedEvent
When I execute a routed command, let's say: ApplicationCommands.Undo.Execute(null, this); WPF does some magic to find the proper CommandBinding on which it executes the ExecutedRoutedEventHandler. Is there a way to get a reference to the CommandBinding (or at least to the handler) that would be executed? It would sometimes be nice...
