    Using Themes
    In This Topic

    You can use a built-in color theme for cells, columns, rows, or sheets. The built-in themes are listed in the ThemeColor class. You can specify a color and a brightness level. A valid range of brightness is from -100 to 100. You can also set a theme for the control with the ThemeColors class.

    You can use font themes for cells, columns, rows, or sheets. The font themes are "Headings" and "Body".

    You can also use XAML themes in the project that affect the control. The vertical and horizontal scroll bars change based on the XAML theme.

    The following elements are changed in the GcSpreadSheet control when you apply a XAML theme to the project:

    The following elements are changed in the filter drop-down window and filter button:

    The following elements are changed for the drag fill handle:

    The following elements are changed for the tab strip:
