This is my 3rd day when I explored the Telerik RadControls for Silverlight. Today, I explored the Masked TextBox control of Telerik. It's a good one and gives several options to use. In this article, I am going to describe you all the APIs of Masked TextBox control and the ways to use it to mask your input. Hope this will help you to understand the control in depth. As always, your feedback and suggestions are always welcome to improve my article content.
