(My english is orrible, be patience).
Entry (and I think also other controls) control uses events (TextChanged, Completed) that are not "Bindable" so it's not possible (or... I don't know how) use these in a MVVM situation.
It's possibile to use Behavior but should be useful if XF had is own solution
I don't know.
Now there is something like
now should exists also
myEntry.SetBinding(Entry.TextChangedEventProperty, "myTextChangedEventProperty"); myEntry.SetBinding(Entry.CompletedEventProperty, "myCompetedEventProperty");
It's permit to use MVVM also with events
