Group Expand Button

Group expand buttons enable end-users to expand or collapse group rows.

Appearance The GridViewAppearances.GroupButton property.

Note: the appearance settings are not in effect if the View is painted using a Windows XP theme (see the BaseView.PaintStyleName property).

Visibility The GridOptionsView.ShowGroupExpandCollapseButtons property.
Custom Draw Event The GridView.CustomDrawGroupRow event.
