TreeListFilterNodeIterator Class

Represents an object that enables you to traverse through nodes displayed within the ASPxTreeList when it is filtered.

Namespace: DevExpress.Web.ASPxTreeList

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


public class TreeListFilterNodeIterator :


Basically, you will need to write recursive code to visit all the nodes contained within the ASPxTreeList. The Nodes Iterator allows you to avoid this, and makes traversing through the nodes a trivial task. All you have to do is to create a new TreeListFilterNodeIterator object, and use its TreeListNodeIterator.GetNext method to obtain the next node.

A start node is specified within the TreeListFilterNodeIterator's constructor. To start traversing from the root node, pass the ASPxTreeList.RootNode as a parameter. The current node is returned by the TreeListNodeIterator.Current property.

To clear any explicitly defined properties and reset the TreeListFilterNodeIterator object to its original, use the TreeListNodeIterator.Reset method.


A Node Iterator can also be created using the ASPxTreeList's ASPxTreeList.CreateNodeIterator method.
