MVVM only fires once with same message

Nov 11, 2015 at 5:02 PM
I have an entry form that the user might save more then once.

I use Message="{Binding Messages, Mode=TwoWay}" in my XAML to get my Toast notification.

It fires once in my view model on the first save, but does not fire again unless the text changes.
is there a way to force to display even if the message hasn't changed?

I am also interested in this issue. I have a toast notification that displays an error when a user tries to do an invalid delete. If they try another invalid delete, I would like the notification to immediately dismiss and then pop up again with the new error. There are multiple error possibility, but if the same error is occurred twice in a row, it should pop up again.

Is there any way to make that work?
