Getting Started with WinForms TabbedForm

This article shows how you can start using RadTabbedForm.

Adding Telerik Assemblies Using NuGet

To use RadTabbedForm when working with NuGet packages, install the Telerik.UI.for.WinForms.AllControls package. The package target framework version may vary.

Read more about NuGet installation in the Install using NuGet Packages article.

With the 2025 Q1 release, the Telerik UI for WinForms has a new licensing mechanism. You can learn more about it here.

Adding Assembly References Manually

When dragging and dropping a control from the Visual Studio (VS) Toolbox onto the Form Designer, VS automatically adds the necessary assemblies. However, if you're adding the control programmatically, you'll need to manually reference the following assemblies:

• Telerik.Licensing.Runtime
• Telerik.WinControls
• Telerik.WinControls.UI
• TelerikCommon

The Telerik UI for WinForms assemblies can be install by using one of the available installation approaches.

Defining the RadTabbedForm

This topic will walk you through the creating process of RadTabbedForm.

1. Create a blank new Telerik Winforms application using the standard template

2. Add a new Tabbed form from Visual Studio. Go to Project -> Add Windows Form and then select TabbedForm
