Namespace: DevExpress.Web.Mvc

Assembly: DevExpress.Web.Mvc5.v19.2.dll

Declaration

C#

public object RootValue { get; set; }

VB.NET

Public Property RootValue As Object

Property Value

Type	Description
Object	An object that represents the root value.

Remarks

By default, if a node’s parent field value doesn’t point to any other node, the node is added to the collection of root nodes (TreeListSettings.Nodes).

However, if you specify the RootValue property’s value, only those nodes whose parent field value matches the RootValue are added to the collection of root nodes. If the node’s parent field value doesn’t match the RootValue, and doesn’t point to any other node, this node isn’t displayed within the TreeList.
