CanExecute Logic for DelegateCommand

Question

Update: The focus became MVVM instead of the actual question so I\'m updating it.

I\'m having a problem with CanExecute for Deleg

Answer 1

There is a bug in the DelegateCommand provided by Prism which doesn't raise the CanExecute event. I beat my head against the wall for a day until I dove into the DelegateCommand class provided by the Prism framework. I don't have the code with me, but I can post my resolution in a bit.

The alternative is to use one of the other RelayCommand frameworks out there.

Edit
Rather than reposting the code, there are other SO questions that provide resolutions:

• WPF-Prism CanExecute method not being called
