Tree View for ASP.NET Web Forms - How to bind the tree to plain data (Unbound mode)

This example demonstrates how to bind ASPxTreeView to data stored in DataTable. Nodes are created in unbound mode.

protected void Page_Load(object sender, EventArgs e) {
    DataTable table = GetDataTable();
    if (!IsPostBack)
        CreateTreeViewNodesRecursive(table, this.treeView.Nodes, "0");
}

private void CreateTreeViewNodesRecursive(DataTable table, TreeViewNodeCollection nodesCollection, string parentID) {
    for (int i = 0; i < table.Rows.Count; i++) {
        if (table.Rows[i]["ParentID"].ToString() == parentID) {
            TreeViewNode node = new TreeViewNode(table.Rows[i]["Title"].ToString(), table.Rows[i]["ID"].ToString());
            nodesCollection.Add(node);
            CreateTreeViewNodesRecursive(table, node.Nodes, node.Name);
        }
    }
}
