Style Customization
This topic describes how the pivot grid’s appearance can be customized with styles.
The ExpressPivotGrid supports different painting techniques. Along with the custom drawing, you are empowered with multiple painting styles features.
First, you can use the TcxPivotGrid.LookAndFeel (TcxDBPivotGrid.LookAndFeel) option, to apply any style from the five predefined styles shown in the image below:
Then, you can use style settings to specify how a group of identical visual elements will be painted.
To meet the requirement for painting each visual element individually, the ExpressPivotGrid control offers a set of events. Below is a list of the pivot grid’s elements whose styles can be customized by handling the related events:
column field values
row field values
The style sheet is a way to save your time and efforts when you need to apply consistent style schemes to a control (see the Styles.StyleSheet property).
And lastly, the LookAndFeel controller component 
(see the TcxLookAndFeelController) – is a powerful mechanism for using a common look and feel.
