Getting Started with WinForms CheckBox

This article shows how you can start using RadCheckBox.

Adding Telerik Assemblies Using NuGet

To use RadCheckBox 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 RadCheckBox

You can add RadCheckBox either at design time or at run time:

Design Time

1. To add a RadCheckBox to your form, drag a RadCheckBox from the toolbox onto the surface of the form designer.
2. In the Properties section of Visual Studio you can change the displayed text next to the check-box by setting the Text property.
3. Double click the check-box in the designer in order to generate the ToggleStateChanged event.
4. Click F5 to start the application.

Run Time

To programmatically add a RadCheckBox to a form, create a new instance of a RadCheckBox, and add it to the form Controls collection.

Adding a RadCheckBox at runtime

public void AddCheckBox()
{
    RadCheckBox checkBox = new RadCheckBox();
    checkBox.ToggleState = Telerik.WinControls.Enumerations.ToggleState.On;
    checkBox.Text = "Is active";
    this.Controls.Add(checkBox);
}

Public Sub AddCheckBox()
    Dim checkBox As New RadCheckBox()
    checkBox.ToggleState = Telerik.WinControls.Enumerations.ToggleState.[On]
    checkBox.Text = "Is active"
    Me.Controls.Add(checkBox)
End Sub
