public virtual bool Expanded { get; set; }
Public Overridable Property Expanded As Boolean

Property Value

Type Default Description


true if the group is expanded, otherwise false.


Use the Expanded property to expand and collapse groups. You can also use the NavBarControl.ActiveGroup property to specify the expanded group.

Collapsing a group by setting the Expanded property to false is only in effect in SideBar Views. This scenario is not supported for Views where only the contents of a single group is visible (Navigation Pane and Side Bar Views). To collapse a group in these Views, you should expand another group instead.


The following sample code toggles a group's expansion state via the NavBarGroup.Expanded property. Individual groups are accessed via the NavBarControl.Groups property.

Groups - Expanded

using DevExpress.XtraNavBar;
for (int i = 0; i < navBarControl1.Groups.Count; i++) {
   NavBarGroup currGroup = navBarControl1.Groups[i];
   currGroup.Expanded = !currGroup.Expanded;
