Silverlight Project - Slide-in and out Panel - How

Question

I don't know what exactly this feature is, but I would like to simulate this in my Silverlight project. I am a C# developer and am moving to Silverlight and Expression Studio (Blend) for richer UX. Let's say I have some user controls and would like them to come into the screen (slide-in and out) as shown in the following site I found:

http://www.templatemonster.com/silverlight-templates/28722.html

On the menu, as one clicks on the menu item, the 'screen' slides to the left and then a new 'screen' slides in from the left to right.

I really want to learn this stuff, but don't know what these 'features' are called? For example what are these 'screens' called in the xaml world? Also, what is the 'slide-in/out' called in the xaml world? Can someone point me to a good article/whitepaper?

Thanks in advance for any advice.

Firstly Silverlight/WPF is really good at this kind of stuff. The framework guys did a great job engineering xaml to be as flexible as possible.

That being said admittingly there’s a lot to get before attempting these sort of things like ResourceDictionaries, Triggers, Actions, Storyboards, Animation (Keyframe/Double...) , Templating, Styles but once you get these metaphors its way easier.

Heres the rundown with some primers.

• Keyframe animation is what this is mostly relying on with some
• Triggers and Actions to orchestrate the
• Visual States which is what the panel looks like 'Open' / 'Closed'

Heres a sample for you pulling this stuff together.

<Grid x:Name="LayoutRoot">
    <VisualStateManager.VisualStateGroups>
        <VisualStateGroup x:Name="CentrePanelStates">
            <VisualStateGroup.Transitions>
                <VisualTransition GeneratedDuration="00:00:00">

                        </DoubleAnimationUsingKeyFrames>
