i'm use blend to create States and I use Timeline to move object from place to place
problem is.. I can't get object's position while timeline is running, Result is freezing
event though i'm use timer to track position
Here is my code.

C#

private void b1_Click(object sender, RoutedEventArgs e)
        {
            state1.Storyboard.Begin();  //play timeline in states
        }

void updatePos_Tick(object sender, object e)
        {
            textblock.text = Canvas.getLeft(myobject);
        }

On the screen, "myobject" is moving but "textblock" doesn't tell me where really are, please help, thanks.

Why don't you bind the textblock text to the objects position in XAML?

I have found answer by myself today (took 3 months haha)
Just use timer tick This...
[C#]

C#

textblock.Text = myMovingCanvas.RenderTransform.GetValue(CompositeTransform.TranslateXProperty).ToString();

Because storyboard's target use this properties...
[xaml]

XAML

<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(CompositeTransform.TranslateX)" Storyboard.TargetName="myMovingCanvas"
