Telerik UI for WPF includes a wide range of controls – from small UI components like Rating to powerful data-driven controls like GridView. The suite provides a variety of data visualization tools to allow you to display and edit your data. Manipulate your row data in a GridView or Spreadsheet and then visualize it through PivotGrid, our charting or diagramming tools. Discover multiple components for daily or business planning such as ScheduleView where users can easily plan their day and GanttView which allows users to visualize and manage any project planning data. Telerik UI for WPF comes complete with customizable UI controls for a variety of needs and options, which makes it the ideal choice for any Windows desktop application.

Give your applications the professional look by applying our built-in themes. Telerik UI for WPF ships with more than ten professionally designed themes. Windows8 and Windows8Touch let you apply styling in real-time. While the new Visual Studio 2013 theme mimics the look and feel of VS 2013.Themes include:

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.

GridView
NEW

    Search criteria are applied on complex properties.
    Introduce ShouldCloseFilteringPopupOnKeyboardFocusChanged property in order to control whether the filtering popup should close on keyboard focus change. Its default value is False. RadGridView's FilteringDropDown ShouldCloseOnKeyboardFocusWithinChanged method now returns True when the user set GridView's ShouldCloseFilteringPopupOnKeyboardFocusChanged property to True.
