Namespace: DevExpress.Web

Assembly: DevExpress.Web.v22.1.dll

NuGet Package: DevExpress.Web

Declaration

C#

public NavBarGroupContentStyle GroupContentStyle { get; }

VB.NET

Public ReadOnly Property GroupContentStyle As NavBarGroupContentStyle

Property Value

Type	Description
NavBarGroupContentStyle	A NavBarGroupContentStyle object that contains the style settings for the group client regions.

Remarks

The GroupContentStyle property provides access to the style settings which define the common appearance style for the client regions of all groups within the navbar control. A group’s client region is considered as an area where group items are displayed - it doesn’t involve the group’s header. The common header style can be defined via the navbar’s ASPxNavBar.GroupHeaderStyle property.

In order to access and change the content style of a particular group within the navbar control, the group’s NavBarGroup.ContentStyle property can be used.

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.
