I love Silverlight and especially how “rich” it looks just by using the standard controls supplied by Microsoft. After you master the controls built-in then you will eventually decide to either build your own controls or find controls that someone has already built for specific requirements. I decided to try the Silverlight RadControls by Telerik because the controls are tested and production ready. If you build your own controls then it will take valuable time that you could be spending elsewhere. This is where Telerik Silverlight RadControls enters the picture. They have built a set of Silverlight controls that adds extended functionality and are very easy to implement in your own project.
