I was quite happy to see the all those sleek new additions to silverlight 5. I will be addressing all of them one by one. For the timebeing i will show how to give that nice and smooth initial animation when a control is loading. Before silverlight 5, this was pretty time consuming as you required to write all those custom animation codes and have their triggers in place. Now all you need to do is the following :
<Grid>
<VisualStateManager.LoadTransition>
<LoadTransition StartXOffset="300" GeneratedDuration="0:0:1.0" StartOpacity="0.2">
<LoadTransition.GeneratedEasingFunction>
<CircleEase/>
</LoadTransition.GeneratedEasingFunction>
</LoadTransition>
</VisualStateManager.LoadTransition>
</Grid>
As we can see above, its a very simple usage. All we need to do is add the VisualStateManager.LoadTransition to our Grid. The parameters are quite self explanatory :
- StartXOffset : The intial x co-ordinate from which to start the transition
- GeneratedDuration : The amount of time it would animate
- StartOpacity : The initial Opacity. Here it start with an initial opacity of 20%
- Also notice that we have added an easing function of type CircleEase. (More details on it at : http://msdn.microsoft.com/en-us/library/ee308751.aspx)
