Created Issue: Transitionals - MediaElement - Blink/restart [8287]

mSchmidt — Tue, 24 May 2011 07:49:57 GMT

Hi

I have been trying to use your transitionals framework to do animations from one "Media" (image or video) to another.
This actually works pretty good, animation is fine.

However, it results in a blink (of black), and if it is a video the video is restarted.
I guess this is a sideeffect of the implemention.

Is there anyway to use the Transitionals transitions without using the TransitionControl ?
This way i could control it my self.

Commented Issue: Any binding is corrupted inside TransitionElement Content [3508]

NickNightingale — Tue, 22 Feb 2011 12:36:59 GMT

When you set any kind of binding between 2 or more objects (controls, paths , etc) and put them as a Content of TransitionElement , The binding is corrupted (broken)
It's an urgent problem

I saw the same thing - ElementName binding does not work inside a TransitionElement.

Commented Issue: The calling thread cannot access this object because a different thread owns it. [7946]

I have an application where a second window is created in a separate thread (say thread2), from the main UI (say thread1). Now in, thread2 itself, within a method, I create a TransitionElement control and make it the child of the thread2 Window. And then create a Canvas that is set to the Content of the TransitionElement.Content. This is where my application throws the thread access error. Following is the StackTrace;

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The error actually originates from the Transitionals.Transitions.StoryboardTransition.BeginTransition() method, when "newContent.Style = NewContentStyle;" is called. The newContent here is my Canavs that I created in Thread2. I have compared the Dispatcher.Thread.ManagedThreadId for newContent and NewContentStyle, which turn out to be different. I would also like to add that I am setting a Transition on the TransitionElement, but of course in the same thread (thread2) as;
Transitionals.Controls.TransitionElement transitionElement =
new Transitionals.Controls.TransitionElement()
{
Transition = new Transitionals.Transitions.CheckerboardTransition()
};
If I do not apply the above Transition then everything works fine.

Now I am just wondering that if the ManagedThreadId of the Canvas and the TransitionElement (created in Thread2) are same, then why is the ManagedThreadId of NewContentStyle different.
I'll appreciate a quick reply. We are running a Sprint.

Thanks and Regards

Observation#2: if I use a Transition that has not been used anywhere in the project before, then it works fine.

Obviously, the reason is that if a transition is used elsewhere before (in my case I had used CheckerboardTransition in the application, before) then the CheckerboardTransitionFrameworkElement is initialized in that thread itself. And when I try to use the same transition in another thread, the instance of CheckerboardTransitionFrameworkElement (and hence its style) become inaccessible.

Obviously there must be some good reason to keep the instance of the CheckerboardTransitionFrameworkElement static. My question is, if there could be a workaround with this problem that, I understand, cannot be singular to my case.

Observation#1: inside the Transitionals.Transitions.CheckerboardTransition class, instead of initializing the instance of CheckerboardTransitionFrameworkElement as static, if I initialize it within the constructor of the CheckerboardTransition class, it works fine.

public class CheckerboardTransition : StoryboardTransition
{
//static private CheckerboardTransitionFrameworkElement frameworkElement = new CheckerboardTransitionFrameworkElement();

public CheckerboardTransition()
{
CheckerboardTransitionFrameworkElement frameworkElement = new CheckerboardTransitionFrameworkElement();
this.NewContentStyle = (Style)frameworkElement.FindResource("CheckerboardTransitionNewContentStyle");
this.NewContentStoryboard = (Storyboard)frameworkElement.FindResource("CheckerboardTransitionNewContentStoryboard");
}

The reason you couldn't view the help file is because of security fixes Microsoft has made which effected these types off help files. Check this blog post out, it will get you rolling on being able to read .chm files in the future:

Commented Issue: Any binding is corrupted inside TransitionElement Content [3508]

Commented Issue: Setting a transition's duration

CommandFusion — Tue, 23 Jun 2009 11:16:18 GMT

I can't find an obvious way of setting the duration of a transition. I have a TransitionalElement on a window and I wish to initialise it with a single Transition which is used everytime the 'Content' changes.

In my Window's constructor, I initialise the TransitionalElement as follows:

transitionElement.Content = new PageOne();

FadeAndBlurTransition transition = new FadeAndBlurTransition();
transition.Duration = new Duration(new TimeSpan(0, 0, 1));
transitionElement.Transition = transition;

The above code throws an exception. Could this be because I am initialising this in the wrong place?

An ideal interface would see an initialising constructor added to FadeAndBlurTransition (and other transitions too) where you could pass in the desired duration, i.e:

FadeAndBlurTransition transition = new FadeAndBlurTransition( new Duration( new TimeSpan( 0, 0, 1 ) ) );

I also don't like the fact that I have to create a new TimeSpan object within the constructor of a new Duration object when you set the duration of a transition. Ideally the initialising constructor would accept the duration in seconds, and would do the appropriate conversion internally.
Comments: ** Comment from web user: CommandFusion **

Is there any way at all to change a transition duration via code? The only way I can see is via XAML. All my transitions are being created at runtime dynamically, and the duration needs to be configurable.

Does this project get any attention anymore? :(

Commented Issue: Changing TransitionElement Content from a UserControl hosted in a Window

CommandFusion — Mon, 22 Jun 2009 06:41:14 GMT

I'm trying to change the TransitionElement Content property directly via a button within a User control.
I can successfully change the content via buttons on the same window as the TransitionElement, but as soon as I try to change the content via an object not directly in the same windows as the TransitionElement, it just doesn't change the content. The Transition Begin and End events still fire, but the content doesnt change.

I have tried both directly calling the content change, and also via the dispatcher such as this:

Partial Public Class UserControl1

Public Delegate Sub ButtonClickDelegate()

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles Button1.Click
My.Windows.Window1.Dispatcher.Invoke(New ButtonClickDelegate(AddressOf ButtonClick), Windows.Threading.DispatcherPriority.Normal)
End Sub

Private Sub ButtonClick()
My.Windows.Window1.TransitionBox.Content = My.Windows.Window1.ObjectA
End Sub
End Class

Any hints?

Created Issue: Add easing to transitions

jdu — Tue, 02 Sep 2008 17:38:13 GMT

Being to add some easing functions to the transitions is much required.
Without easing transitions feels too "harsh". Every GUI that feels "smooth" has eased animations.

Created Issue: Content is oversized when transitioning

br1 — Mon, 11 Aug 2008 15:47:31 GMT

Certain transtitions, for example DoorTransition, enlarge the old content when animating. See attached example solution. I've found out that if a background color is set, this doesn't happen.

Commented Issue: Setting a transition's duration

james_bird — Wed, 30 Jul 2008 11:57:18 GMT

The exception that is being thrown is "CTP1 does not support changing the duration of this transition". If it isn't possible to change the duration of the transition after it has been created, would it be possible to initialise the duration on construction?
