Property Value

Type	Description
Paddings	A Paddings object that contains padding settings.

Remarks

The Paddings property provides access to the padding settings which are defined by the navbar control. Paddings defined at the navbar level are considered as the amount of spaces between the outer boundary of the navbar control and the boundaries of its groups.

Example

This example demonstrates how to automatically expand a NavBarGroup when the mouse hovers over a group header. This functionality is turned on by setting the ExpandGroupAction property to MouseOver``, and it may be extremely useful for the @DevExpress.Web.ASPxNavBar with @DevExpress.Web.ASPxNavBar.AutoCollapse set toTrue` and when all groups have the same height.
