Telerik R1 2019 Release_870x220

Check out everything that's new in Telerik UI for WinForms with the R1 2019 release.

The beginning of the new 2019 year brings to your attention the R1 2019 release of Telerik UI for WinForms. It offers a multifarious set of new controls, .NET Core 3 & Visual Studio 2019 support and enhancements that will improve the customers’ experience. Google Chrome-like forms, text-box with embedded buttons, font selection control, crystal dark design is just a small part of the packed new features that tickles your eagerness to continue reading.

Let’s go over what is coming with R1 2019:

.NET Core 3 & Visual Studio 2019 support

We are super excited to announce that the Telerik UI for WinForms controls are .NET Core 3.0 Preview compatible! We introduced a new set of binaries built against .NET Core 3.0 so you can benefit from all the introduced features in the framework. We will continue shipping them in the future releases together with the other binaries.

The Visual Studio Extensions and our installers are fully compatible with Visual Studio 2019 so if you are excited about everything new – you can install and use them with Visual Studio 2019 right now.


RadTimeSpanPicker is a UI component that provides a full control over selecting a specific time span and duration within certain ranges using the built-in components for days, hours, minutes, seconds and milliseconds. It comes with negative values support, data binding, localization and right to left functionality out of the box. GridTimeSpanPickerEditor wraps the RadTimeSpanPicker control in the new column that RadGridView offers. Thus, you can achieve TimeSpan values mapping out of the box.



RadFontDropDownList represents a drop-down list with built-in fonts that are installed on the system. Once you drag and drop the control onto the form, it is populated with all fonts installed on the machine and it is not necessary to do it programmatically. It saves our users’ development time. Recently used fonts are displayed along with a full list of all fonts. The select on hover functionality is quite eye-candy and allows to change the font easily in the associated text control.



Modern browsers inspired form is here. RadTabbedForm displays tabs in the title bar just like in most modern Web browsers. It allows customizing the tabs like adding buttons or other elements in front or after the tabs. You can pin the tabs or reorder them via drag and drop. Each tab can be opened as a standalone window.



Embedding button elements inside RadTextBox has been a highly demanded feature for quite some time. Although we always offered to our customers appropriate solutions for their scenarios thanks for the highly customizible Telerik Presentation Framework, we are thrilled to announce the new RadButtonTextBox control. Now, you can very easily insert button (and other) elements on the left or right side of the editable part.


CrystalDark Theme

The CrystalDark theme is the latest addition to our themes pack as we are aware of our customers’ inclination to use dark themes in their applications. Go ahead and give it a try in the ThemeViewer tool.


Crystal Themes Blending

As a continuation of the Material and Fluent themes blending, the Crystal themes are also designed to work with a predefined set of colors. Thus, using Visual Style Builder you can generate different color variations of the Crystal and CrystalDark themes. A completely new theme can be created for a couple of minutes.
