Property Value

Type	Default	Description
ExpandButtonPosition	Default	One of the ExpandButtonPosition values.

Available values:

Name	Description
Default	For a group, indicates that the expand button position depends upon the navbar level’s `ASPxNavBar.ExpandButtonPosition` property setting. For a navbar, corresponds to the ExpandButtonPosition.Right value.
Left	The expand button is displayed at the left of a group’s header.
Right	The expand button is displayed at the right of a group’s header.

Remarks

Use the ExpandButtonPosition property to control the position of the expand button within the navbar’s groups. This property’s value is applicable to all the groups of the navbar control. A particular group’s expand button position can be specified via the group’s NavBarGroup.ExpandButtonPosition property which overrides the value assigned to the ExpandButtonPosition property.

Example

The example demonstrates how to create the ASPxNavBar groups and items at runtime to create a FAQ page.

Data can be obtained from any type of a datasource. For example, the data can be obtained from the Access database file using the OLE DB provider.The sample was built from the kindly provided How to use the ASPxNavBar with an Access or SQL datasource suggestion article, containing the URL to the tutorial video file.
