Description Hakan 2017-05-19 23:02:54 UTC
Defining a delegate property by method name in XAML works in WPF but it does not work in Xamarin Forms.
You can try this by having the following property in a subclassed button:

  class Button2 : Button
    {
        public Func<int, int> MyFunc { get; set; } = null;


    }

 <ContentPage.Content>
        <StackLayout>
            <Button2 x:Name="btn" MyFunc="DoSomething"></app3:MyCoolButton>
        </StackLayout>
    </ContentPage.Content>

private int DoSomething(int foo)
        {
            return foo++;
        }
