Exceptional Performance and User Experience

Telerik UI for WPF enhances user experience by providing both UI and data virtualization. Use Telerik’s 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 makes 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.



Intuitive API
Telerik UI for WPF 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 API is a close mirror of Microsoft. If you’ve worked with the WPF Framework and Microsoft’s XAML Controls, you’ll get up and running fast in Telerik UI for WPF.



Document Processing

Three components enable you to process the most common text, 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:

DOCX
RTF
TXT
HTML
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

The ability to drag-and-drop a complex control from our toolbox, wire up a few events, receive quick functionality, then move on to the next work item makes your software development easier. 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 WPF fully supports MVVM, allowing you to create reliable, well-structured and easily maintainable applications.
