Flyout Tasks Never Complete

[KuroThing]

When using an AsyncRelayCommand and the FlyoutManager, the task is never completed, so the command's CanExecute check always returns false.

I cannot reproduce this issue. The ViewModel of Flyouts must derive from DialogViewModel, and if you call DialogViewModel.Close(), the flyout's task will complete. Please have a look at the demo application.

That is kind of the problem, afaik there is no mechanism in place so that when a flyout is closed by the default button, that the close method is called? So the Task is never set to be completed?

[thoemmi]

Are you talking about the "arrow" button in the header? If your view is derived from Flyout, you can bind your view's CloseCommand to a command provided by your viewmodel, which in turn can call DialogViewModel.Close().

If your view is not derived from Flyout but a general UserControl, than you're right, the task will never complete. Unfortunately, I didn't pay attention to that scenario yet.

Ahh i see, i was missing the CloseCommand binding part of it, i didn't realise the Flyout provided a way to do that using the default arrow button.
