Gets the row handle that identifies the node.

Namespace: DevExpress.Data.TreeList

Assembly: DevExpress.Data.v19.1.dll

Declaration

C#

public int RowHandle { get; }

VB.NET

Public ReadOnly Property RowHandle As Integer

Property Value

Type	Description
Int32	An integer value that specifies the row handle.

Remarks

A node can be identified by its key value (in bound mode), content and row handle. Visible nodes (that are not hidden within collapsed nodes) can also be identified by visible indices.

The following images illustrate the difference between row handles and visible indices.

• All nodes are expanded.

  

• One node is collapsed.
