Visibility Hidden Behavior for WinRT

In my last post, I lamented the loss of the Hidden in the Windows.UI.Xaml.Visibility enumeration. Here’s an ultra-simple attached property that simulates Hidden by changing the opacity and hit testability of the element:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

using Windows.UI.Xaml;   namespace Blog.VisibilityHiddenDemo {     public class VisibilityHiddenBehavior : DependencyObject     {         public static readonly DependencyProperty IsVisibleProperty =             DependencyProperty.RegisterAttached("IsVisible", typeof(bool), typeof(VisibilityHiddenBehavior),                 new PropertyMetadata(true, OnIsVisibleChanged));           public static bool GetIsVisible(DependencyObject obj)         {             return (bool)obj.GetValue(IsVisibleProperty);         }           public static void SetIsVisible(DependencyObject obj, bool value)         {             obj.SetValue(IsVisibleProperty, value);         }           private static void OnIsVisibleChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)         {             var element = d as FrameworkElement;             if (element != null)             {                 var visible = (bool)e.NewValue;                 element.Opacity = visible ? 1 : 0;                 element.IsHitTestVisible = visible;             }         }            } }

Free as in beer.

Happy coding.
