TreeListNode.Expanded Property

Gets or sets whether the node is expanded.

Namespace:DevExpress.XtraTreeList.Nodes
Assembly:DevExpress.XtraTreeList.v19.1.dll

Expanded Syntax

Property value

Type: Boolean
true, if the node is expanded; otherwise, false.
The default is false.

Expanded Remarks

Set the Expanded property to true to display child nodes of the current node. If set to false, the current node collapses and all its child nodes are hidden.

If the HasChildren property is set to false, setting the Expanded property to true does nothing. When the HasChildren property is set to true, setting the Expanded property to true causes the Tree List to fire the TreeList.BeforeExpand event. It allows the dynamic loading feature to be implemented in Unbound Mode.
