RSS Widget 2 In Silverlight 3 with Data Persistence


This is a new Version of my old RSS Widget Article. As you will see it has the feature of data persistence using ISO Storage.

Creating the Silverlight Project

We will create a simple Silverlight Project and name it asRSSFeedWidget2.

Designing our Sample Application

I have used Blend 3 to design our simple application. I have kept one TextBox where the user can paste the RSS Feed URL and two buttons, one for search feed data and the other one for adding the URL into persistence (ISO Storage). I have used three png images to accomplish my design.
