Easing Functions - XAML Syntax

DoubleAnimation...DoubleAnimation.EasingFunction vs. DoubleAnimationUsingKeyFrames...EasingDoubleKeyFrame

Samples here

In the previous example, the easing functions are applied to a From/To/By animation. You can also apply these easing functions to Key-Frame animations using either EasingDoubleKeyFrame, EasingPointKeyFrame, or EasingColorKeyFrame 

Using VisualStateManager in Code

Attached Properties are DependencyProperties

See "Attached Properties" at http://www.wpftutorial.net/dependencyproperties.html

DoubleAnimation, DoubleAnimationUsingKeyFrames

1. DoubleAnimation - Uses a From/To direction.
2. DoubleAnimationUsingKeyFrames - This is a container for a set of key frames that will determine the value at a given set of points along a time line. We will look at this option in our next tip of the day.

Control, ContentControl, ItemsControl

Differences between when inheriting and the Visual Tree/Leaf paradigm.

DependencyObject/DependencyProperty

DependencyProperty's (e.g. a Canvas' left, right) are assigned to DependencyObjects, e.g. UI elements. http://blog.hackedbrain.com/2004/12/04/understanding-dependencyobject-and-dependencyproperty/

Example usage of DependencyProperty to add second ContentPresenter to a ControlTemplate

For the uncommon cases where a settable property on a DependencyObject is not a dependency property, that property will be unable to support animation, data binding, or FrameworkElement styling.

XAML Concepts

See http://msdn.microsoft.com/en-us/library/ms752059.aspx for descriptions of:

XAML Object Elements (represent WPF types)
Property Element Syntax (vs Attribute Syntax)
Markup Extensions - for setting property dynamically at runtime
Type Converters (e.g. Margin/Thickness)
