TreeListNodeFilterEventArgs.Visible Property

Gets or sets the processed node’s visibility.

Namespace: DevExpress.Xpf.Grid.TreeList

Assembly: DevExpress.Xpf.Grid.v19.2.dll

Declaration

C#

public bool Visible { get; set; }

VB.NET

Public Property Visible As Boolean

Property Value

Type	Description
Boolean	true to show the node; otherwise, false.

Remarks

To hide or show a node, specify the Visible property, and set the TreeListNodeFilterEventArgs.Handled property to true. If the TreeListNodeFilterEventArgs.Handled property is set to false, the node’s visibility is determined by the filter currently applied to a View. So, the node will only be visible if it matches the View’s filter. Otherwise, it will be hidden.
