## Format Rules

The **Format Rules** list displays the style format rules that are stored in the Pivot Grid Control’s [PivotGridControl.FormatRules](/WindowsForms/DevExpress.XtraPivotGrid.PivotGridControl.FormatRules) collection. Use the ![Group_AddGroup](/WindowsForms/images/group_addgroup21418.png) and ![Group_RemoveGroup](/WindowsForms/images/group_removegroup21419.png) buttons to add a new item to and delete the selected item from the collection, respectively.

The selected item’s properties can be accessed using the built-in property grid within the **Properties** tab.

The **Rule** tab is designed to make it easier to customize the style rule’s appearance settings.
