GridControl supports two built-in themes - Light and Dark. The Themes class stores the theme names. To apply the desired theme to a grid, assign an appropriate Themes field to the ThemeManager.ThemeName property. For more information, refer to How to: Apply Themes.
You can use the applied theme as is, or customize its appearance (if required). To customize the current theme, use ThemeBase class's properties. To learn more, see the example below.
The ThemeBase class's properties provide access to different customizers, which you can adjust to change appearance settings (for example, font attributes, border and background colors, etc.) of the grid's corresponding visual elements (such as data cells, group rows, filter panel, etc.). In this example, the following customizers are used.
To apply the customization, call the ThemeManager.RefreshTheme method.
This example customizes the Light theme as it is shown in the image below.
