In my previous article Data Binding in Silverlight Accordion Control using XML we show how to bind Accordion control using XML data file.

This article is going to explain how to bind each Accordion items dynamically and how to put different colors and styles to every Accordion Item.

Getting Started -

Creating a Silverlight Application:

Open Visual Studio 2010.
Go to File => New => Project.
Select Silverlight from the Installed templates and choose the Silverlight Application template.
Enter the Name and choose the location.
Click OK.

In the New Silverlight Application wizard check the "Host the Silverlight Application in a new Web site".

Click OK.
Adding an image in the solution:
Right click on the solution, select Add => New Folder.
Name the folder as Images and click OK.
Right click on the Images folder, select Add =>Existing Item.
Choose the image and click Ok.

First of all right click on ClientBin folder and add a new .XML data file.

Here is my .xml data file.
