ASPxNavBar.Paddings Property
Gets the padding settings of the navbar control.
Namespace: DevExpress.Web
Assembly: DevExpress.Web.v19.2.dll
Declaration
public Paddings Paddings { get; }
Public ReadOnly Property Paddings As Paddings
Property Value
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 NavBar with AutoCollapse set to True and when all groups have the same height.
