Property Value

Type Description

A TreeViewNode object representing the node’s immediate parent.


Use the Parent property to identify and access the immediate parent node which owns the current node.


The sample code below represents an ExpandedChanging event handler. The event handler prevents collapsing nodes if it has selected children in any generation.

<dx:ASPxTreeView ID="ASPxTreeView1" runat="server" DataSourceID="XmlDataSource1" AutoPostBack="True" 
    AllowSelectNode="True" OnExpandedChanging="ASPxTreeView1_ExpandedChanging" />
<asp:XmlDataSource ID="XmlDataSource1" runat="server" DataFile="~/App_Data/MenuTabbedMenu.xml"
protected void ASPxTreeView1_ExpandedChanging(object source, DevExpress.Web.ASPxTreeView.TreeViewNodeCancelEventArgs e) {
    if ((e.Node.Expanded) && (ASPxTreeView1.SelectedNode != null)) {
        TreeViewNode  node = ASPxTreeView1.SelectedNode.Parent;
        while (node != null) {
            if (e.Node == node) {
                e.Cancel = true;
            node = node.Parent;
