Is it possible to trigger an AnimationBehavior from a ViewModel

[bijington]

I would like to perform a ShakeAnimation on a Button if I cannot execute the Command in the ViewModel rather than just disabling the button. Is it possible to trigger the animation from the ViewModel side? As far as I can tell AnimationBehavior currently relies on events which I don't think helps me in this case.

I didn't look at ShakeAnimation implementation yet but according to your statement, just guessing (i might be wrong) that EventToCommandBehavior may be useful in this case.

Thanks for the quick response!

I am not sure it does help me unless my understanding is completely wrong. As I understand it EventToCommandBehavior still deals with something happening in the View and then it being able to perform something within the ViewModel. Is that correct?

Perhaps what I want to achieve or at least how I thought to achieve it was wrong... essentially I have a number of Entry controls that have some level of validation performed on them. I then have a create button which when press I would like to either shake all the invalid Entry controls or at least just the create button. I thought this would be triggered from the ViewModel.

This terrible drawing shows what I am thinking:

No, now it's not possible. But it can be quite easily added, I am sure

if you wish, you can open an issue with feature-request.)

@AndreiMisiukevich great thanks for the confirmation. I will raise it as a feature request and I'll be happy to provide the effort in implementing it 🙂

awesome)

It should be a command with OneWayToSource binding mode (You can check how I implemented it in Expander - ForceUpdateSizeCommand)
