It is possible to set one Icon so, that it would be used on every window in current app. So that i set it once (not on every window by hand)..?
You can also try this to set your own icon:
private void Page_Loaded_1(object sender, RoutedEventArgs e) { Uri iconUri = new Uri(@"C:\Apps\R&D\WPFNavigation\WPFNavigation\Images\airport.ico", UriKind.RelativeOrAbsolute); (this.Parent as Window).Icon = BitmapFrame.Create(iconUri); }
