Customizing the look and feel of a control is an important part of the application development which is required to give it a seamless user interface. Our Themes for WinForms provides an easy and intuitive way to apply themes to all ComponentOne controls. It allows you to style the control using the **C1ThemeController** component and **C1ThemeDesigner** application.

## Using C1ThemeController

The **C1ThemeController** component can be used to apply built-in themes to the controls. The component loads and manages visual themes and applies them to the control. You can simply drag and drop the **C1ThemeController** from the toolbox on your form and use the built-in themes to style the control. For example, BeigeOne, Material, MaterialDark, Office2016Green, etc. are some available built-in themes.

The following GIF shows different themes getting applied on the **C1BulletGraph** control.

To apply a built-in theme to the Bullet Graph control, follow these steps:

1.  Drag and drop the **c1ThemeController** and **C1BulletGraph** controls on the form. Observe that the **c1ThemeController** is added to the Component tray.
2.  Right-click the **C1BulletGraph** control and select Properties from the context menu.
3.  In the Properties window, click the dropdown next to the Theme on **c1ThemeController1** property and select a theme from the ComponentOne themes list.

## Using C1ThemeDesigner application

**C1ThemeDesigner** application provides you an easy-to-use UI so that you can create your own themes or modify the existing ones. The application gets installed on your system along with ComponentOne WinForms Edition and can be accessed through **C1ThemeDesigner.4.exe** kept at C:\\Program Files (x86)\\ComponentOne\\Apps\\v4.0. For more information on using **C1ThemeDesigner** application to create and modify themes, see [C1Theme Designer Application Overview](https://developer.mescius.com/componentone/docs/win/online-themes/overview.html).
