WPF 4.5 Binding to static properties

Question

I have a static property in my class like

 public partial class ShellWindow { private static Visibility progressbarVisibility = Visibility.Collapsed; public static Visibility ProgressbarVisibility { get { return progressbarVisibility; } set { if (progressbarVisibility == value) return; progressbarVisibility = value; RaiseStaticPropertyChanged("ProgressbarVisibility"); } } public static event EventHandler<PropertyChangedEventArgs> StaticPropertyChanged; public static void RaiseStaticPropertyChanged(string propName) { EventHandler<PropertyChangedEventArgs> handler = StaticPropertyChanged; if (handler != null) handler(null, new PropertyChangedEventArgs(propName)); } }

I am creating a control in code behind and wanted to bind it with this property. Currently i am doing like this

var binding = new Binding("ShellWindow.ProgressbarVisibility") { Mode = BindingMode.TwoWay }; binding.Source = this; progressbar = new CircularProgressBar (); progressbar.SetBinding(VisibilityProperty, binding);

This binding is not working. I am tring to follow this article but i didn't get where i am doing wrong.

Take a look at this post, I think it will help: stackoverflow.com/questions/936304/binding-to-static-property — TrueEddie

In .NET 4.5 you can notify WPF of a change to a static property, however I believe it is different than how you normally handle a property changed. You must create event for each static property that can be notified of a change. The event must be titled with the property name, and have a suffix of PropertyChanged.

I found this article that may help you out: http://10rem.net/blog/2011/11/29/wpf-45-binding-and-change-notification-for-static-properties
