Gets or sets the value that root nodes contain in the field specified by the TreeListSettings.ParentFieldName property.
Namespace: DevExpress.Web.Mvc
Assembly: DevExpress.Web.Mvc5.v24.2.dll
Declaration
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.
