Build Interactive Content Slider using Accordion Control in Silverlight 4


The Accordion is a web control that allows you to provide multiple panes and display them one at a time. It is like having several CollapsiblePanels where only one can be expanded at a time. The Accordion is implemented as a web control that contains AccordionPane web controls. Each AccordionPane control has a template for its Header and its Content. We keep track of the selected pane so it stays visible across postbacks.

Note: You need to add a reference to the System.Windows.Controls.Toolkit to your project.
 

In this code sample, I create an interactive user interface with the help of the Accordion control. 

Here is an example of Accordion:

<UserControl x:Class="SilverlightApplication7.MainPage"  xmlns:layoutToolkit="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Layout.Toolkit"

</UserControl>

 

Just build and run this application. If you copy the code, you may need to add your own images.

As you can see from the following images, there are 5 accordion items. If you click on an item, the content related to that item will load and you will see a smooth slider effect.

Summary

In this article, I demonstrated the use of an Accordion control available in Silverlight 4. You an see using this control, you can design RIA applications and give them a makeover the way you like.
