Remarks
Important
This documentation topic describes legacy technology. We no longer develop new functionality for the GridControl and suggest that you use the new DataGridView control instead.
GridControl provides you with two predefined themes - Light and Dark. The Default theme depends on the mobile platform. For iOS applications, the Default theme is Light, for Android - is Dark. To apply another theme to a grid, use the ThemeManager.ThemeName property. Then, you can customize the applied theme (if needed). For more information, see the How to: Customize Themes document.
Example
This example demonstrates how to customize a theme used to paint a GridControl.
To apply a theme to a GridControl, assign its name to the ThemeManager.ThemeName property. The Themes class stores available theme names.
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.
ThemeBase.HeaderCustomizer- ThemeBase.CellCustomizer
- ThemeBase.TotalSummaryCustomizer
- ThemeBase.NewItemRowCustomizer
Important
To apply the customization, call the ThemeManager.RefreshTheme method.
This example customizes the Light theme as it is shown in the image below.
