Change Button image of Button for ViewCell in ListView

Hi Xamarin Experts,

I know how to bind a Command to a button function from a ViewCell item (using <Button Command="{Binding DeleteCommand}"... )

But how can I bind to which image I want to display based on current state? If I want the image to change from "DeleteButton" to "MarkedForDelete" image, what can I do?

Many thanks!
Mike
