Namespace: DevExpress.XtraTreeList

Assembly: DevExpress.XtraTreeList.v24.1.dll

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

Declaration

C#

public virtual object GetDataRecordByNode(
    TreeListNode node
)

VB.NET

Public Overridable Function GetDataRecordByNode(
    node As TreeListNode
) As Object

Parameters

Name	Type	Description
node	TreeListNode	The TreeListNode object representing the node whose associated data row is to be obtained.

Returns

Type	Description
Object	A data row associated with the node specified. null (Nothing in Visual Basic) if the node is not found.
