Cancel backstage close event

[lilhoser]

Is there a way to do cancel a backstage close event? I only see IsOpenChanged which does not allow setting e.Cancel on the event in question. The use case is a delayed operation on a form in the backstage needing to complete.

Currently there is no way to do so.
But it sounds like a good addition.

Just had a look at the code and you can prevent closing the Backstage already.

Just set CanChangeIsOpen to false to prevent the Backstage from being closed during your delayed operation.

Would be nice if you could report back if that worked in your situation.
