# Applying a Theme to a Control

To apply a custom theme from **[RadThemeManager](https://www.telerik.com/products/winforms/documentation/tools/theme-manager/adding-radthememanager-to-a-form)** to a RadControl, first select the control on the form. From the drop-down list in the control **ThemeName** property, select the theme. The list of themes supplied by **RadThemeManager** will be merged with the list of predefined themes supplied for the control.
