TreeListView.FetchSublevelChildrenOnExpand Property

Gets or sets whether the TreeListView fetches child nodes of sub-level nodes when their parent node is being expanded. This is a dependency property.

Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v18.2.dll

Declaration

C#

public bool FetchSublevelChildrenOnExpand { get; set; }

VB.NET

Public Property FetchSublevelChildrenOnExpand As Boolean

Property Value

Type	Description
Boolean	true to fetch child nodes of sub-level nodes when their parent node is being expanded; otherwise, false.

Remarks

If the FetchSublevelChildrenOnExpand property is set to false and a node is being expanded, all its child (sub-level) nodes display expand buttons, even if they do not have children. An expand button is automatically hidden when expanding a sub-level node that does not contain child nodes.
