Exceptional Performance and User Experience
Telerik UI for Silverlight enhance user experience by providing both UI and data virtualization. Use Telerik UI Controls to display large amounts of data, with virtually no performance trade-off. What you get is exceptional performance and a sleek end-user experience. Telerik UI Controls make your apps fast by:

Producing minimal and clean XAML
Allowing you to load only the data within the current viewport of the application
Implementing lazy loading – loading data only when it is requested
Minimizing memory usage, robust code free from memory leaks

Document Processing

Two new components enable you to process the most common spreadsheet and PDF file formats without having Microsoft Office or other third-party libraries installed. Your application users will be able to create, load and modify documents in a variety of formats including:

PDF
XLSX
CSV
Tab-delimited

Enable your application to seamlessly export and import documents or convert them from one format to another. All thanks to the intuitive and easy-to-use APIs.

MVVM Support
Software development is made easier with the ability to drag-and-drop a complex control from our toolbox, wire up a few events, receive quick functionality, and then move on to the next work item. Those functionalities, however, do not guarantee that the software created is well structured, easily extensible, and unit testable. MVVM resolves those issues. Telerik UI for Silverlight fully supports MVVM, allowing you to create reliable, well-structured and easily maintainable applications.

Touch Support
The built-in touch support and the Windows8Touch theme make your Telerik UI for Silverlight powered applications run smoothly on a touch device.

Intuitive API
Telerik UI for Silverlight has a short learning curve and is easy to use. The suite provides for:

Seamless integration with your Visual Studio Toolbox for quick drag and drop usage
Feature configuration using Design-time Wizards
Easy to learn API
The Telerik UI Controls API is a close mirror of Microsoft. If you’ve worked with the Silverlight Framework and Microsoft’s XAML Controls, you’ll get up and running fast in Telerik UI Controls for Silverlight

Export Support
Export the data that different controls display with a functionality that enables your users to view and manipulate their data even after an application is closed. Telerik UI for Silverlight provides you out-of-the-box export functionalities and options. Most of the data-driven controls allow you to export data to a variety of formats.
