# Adding RadThemeManager to a Form

**RadThemeManager** is an non-visual component that manages the connection between themes (stored in XML files) and Telerik UI for WinForms controls on your form. To apply a theme to a control, the form containing the control must also contain a **RadThemeManager**.

There are two ways to add a **RadThemeManager** to your form:

* From the toolbox.

* From the **Smart Tag** menu of any Telerik RadControl.

## Adding a Theme Manager from the Toolbox

From the **Telerik UI for WinForms** tab of the toolbox, drag a **RadThemeManager** component and drop it anywhere on your form. This action will create a **RadThemeManager** control in the form component tray area.
