Gets or sets the name of a logical check group to which the menu item belongs.
NuGet Package: DevExpress.Web.Office
A String value that specifies the group name.
A menu item can function as a check box if the item belongs to a logical group defined via the item’s CheckedGroupName property. To arrange an item/items into a logical group, set its/their CheckedGroupName property to the same value. Arranging several menu items into a group makes them function as radio buttons - checking an item unchecks the one previously selected. So, only one menu item in a group can be checked at one time.
