Here is a ListView with a DataTemplate containing a Switch and a Label.

Should the label exceed the width of the View, it is not wrapped, no matter which of the following is modified:

o The LineBreakMode
o The configuration of Horizontal and Vertical orientations for the StackLayout
o Any propery on the ListView

Sample code (basically a replacement for the ListViewDemo class in the FormsGallery demo:

    class ListViewDemoPage : ContentPage
        class Person
            public Person(string name, bool isSubscriped)
                Name = name;
                IsSubscriped = isSubscriped;

            public string Name { private set; get; }
            public bool IsSubscriped { get; set; }

        public ListViewDemoPage()
            var header = new Label
                Text = "ListView",
                Font = Font.BoldSystemFontOfSize(NamedSize.Medium),
                HorizontalOptions = LayoutOptions.Center,

            var people = new List<Person>
                new Person("this is a very long message aaaa bbb ccc ddd eee ", true),
                new Person("this is a very long message aa bb cc dd ee ff gg hh ii jj kk", true),
                new Person("this is a very long message", false),
                new Person("this is a very long message", true),
                new Person("this is a very long message", false),
                new Person("this is a very long message", true),
                new Person("this is a very long message", false),
                new Person("this is a very long message", true),

            var listView = new ListView
                HasUnevenRows = true,
                RowHeight = 100,
                ItemsSource = people,
                ItemTemplate = new DataTemplate(() =>
                    var label = new Label()
                        HorizontalOptions = LayoutOptions.Start,
                        VerticalOptions = LayoutOptions.CenterAndExpand,
                        LineBreakMode = LineBreakMode.CharacterWrap,
                        Font = Font.SystemFontOfSize(20),
                        TextColor = Color.White

                    var switcher = new Switch
                           HorizontalOptions = LayoutOptions.Start,
                           VerticalOptions = LayoutOptions.CenterAndExpand

                    label.SetBinding(Label.TextProperty, "Name");
                    switcher.SetBinding(Switch.IsToggledProperty, "IsSubscriped");

                    return new ViewCell
                        View = new StackLayout
                            Padding = new Thickness(0, 5),
                            Orientation = StackOrientation.Horizontal,

                            Children =

            Padding = new Thickness(10, Device.OnPlatform(20, 0, 0), 10, 5);

            Content = new StackLayout
                Children =

Forgot to mention. If the Switch is removed from the StackLayout, wrapping happens as expected.

I have checked this issue and able to reproduce it.

Steps to reproduce this issue.

1. Create a Xamarin Forms PCL Application.
2.Add a class (.xaml) , add above code and did some modification in it.
3.Run the Application.

I observed that Listview having label in this demo .first and second label  width crossed the width of screen ,complete text of first label not able to see but second label text shifted to another line.

I checked on Emulator API18
