Getting Started with WinForms LinearGauge
This article shows how you can start using RadLinearGauge.
Adding Telerik Assemblies Using NuGet
To use RadLinearGauge 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 RadLinearGauge
This article shows how you can add the control at design time or with code
Design Time
When you drag a RadLinearGauge from the Toolbox and then drop it on the form, the gauge gallery will offer you to pick up the desired type:
Figure 1: Gallery Types
If you do not choose a gauge's style and just close the gallery, an empty RadRadialGauge will be created.
You can open the gallery from the smart tag as well.

Adding Items Programmatically
This example demonstrates how to programmatically setup a linear gauge.
