ASPxNavBar.EnableAnimation Property

Gets or sets a value that specifies whether a specific animation effect is used when expanding/collapsing groups.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v23.2.dll

NuGet Package: DevExpress.Web

Declaration

C#

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

VB.NET

<DefaultValue(False)>
Public Overridable Property EnableAnimation As Boolean

Property Value

Type	Default	Description
Boolean	false	true if a specific animation effect is used; otherwise, false.

Remarks

When the ASPxNavBar.AutoPostBack property is set to false, group expanding/collapsing can be performed with a specific animation effect. Use the EnableAnimation property to control whether this predefined animation effect is available for the navbar control. Note that if the ASPxNavBar.EnableCallBacks property is set to true, the animation effect is not used when a collapsed group is expanded for the first time - via a callback.

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.
