• Support for the following interfaces: ICommand, IValueConverter, IList, IDictionary, INotifyPropertyChanged, and INotifyCollectionChanged. This means that you can implement them and NoesisGUI will understand each one. For example, you can have a custom implementation of IList in your VM.
• VMs can now be implemented without deriving from BaseComponent. Implementing INotifyPropertyChanged is enough right now.
• Support for generics. We provide also ObservableCollection<T>
• A preview of Windows Store is included in this version.

Is there any reason why the storyboard completed function never fires?

Edit: it does in fact fire but it won't let me set the value of the progressbar back to 0 it just stays at 100.

Code: Select all

pbReload = FindName<Noesis.ProgressBar>("pbReload");
sbReload = root.FindResource<Storyboard>("sbReload");
sbReload.Completed += sbReload_Completed;
sbReload.Begin(pbReload, pbReload, true);

void sbReload_Completed(object sender, TimelineEventArgs e)
{
    //This never fires
    //pbReload.Value = 0;
}

DependencyProperty follows a value precedence scheme to determine how to obtain the effective value of the property. As you can see in the previous link, an animated value has precedence over a local value (when you do a SetValue).

So when a property is animated, and you want to set a new value in code, you need to clear the property first:

Code: Select all

rectangle.ClearAnimation(Shape.StrokeThicknessProperty);
rectangle.SetStrokeThickness(2.0f);

I have to check again the behavior of WPF, but I think it should be done the same way.
Anyway I'm seeing we have a different API compared to WPF, we will change it to make code compatible between WPF and Noesis.

The animation value is just another value source, in fact the animation value is not modifying the local value (that remains the same during all the animation duration). You can specify how your storyboard behaves when the animation completes by setting the FillBehavior property:

• <Storyboard x:Key="anim"> or <Storyboard x:Key="anim" FillBehavior="HoldEnd"> is the default behavior, that will maintain the last animated value after animation ends.
• <Storyboard x:Key="anim" FillBehavior="Stop"> will remove last animated value after animation ends, so the local (or any other value with less precedence) will be recovered.

I guess I should also note it doesn't look like setting the duration of the storyboard is working in code.

Code: Select all

sb.Duration = new Duration(new Timespan(0,0,5)); // 5 seconds
sb.Duration = new TimeSpan(0,0,5); // 5 seconds

I get the same result for both of these it looks like it just lasts for about 1 second.
