NavBarGroup.Expanded Property

Gets or sets a value specifying whether the group is expanded.

Namespace: DevExpress.XtraNavBar

Assembly: DevExpress.XtraNavBar.v23.2.dll

NuGet Packages: DevExpress.Win, DevExpress.Win.Navigation

Declaration

C#

[DefaultValue(false)]
[XtraSerializableProperty]
public virtual bool Expanded { get; set; }

VB.NET

<DefaultValue(False)>
<XtraSerializableProperty>
Public Overridable Property Expanded As Boolean

Property Value

Type	Default	Description
Boolean	false	true if the group is expanded, otherwise false.

Remarks

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.

Example

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

C#

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

VB.NET

Imports DevExpress.XtraNavBar
' ...
Dim I As Integer
For I = 0 To NavBarControl1.Groups.Count - 1
   Dim CurrGroup As NavBarGroup = NavBarControl1.Groups(I)
   CurrGroup.Expanded = Not CurrGroup.Expanded
