+# How to Populate Nodes Without Binding Data as Unbound Mode in WPF TreeView?
+
+This repository describes how to populate nodes without binding data as unbound mode in [WPF TreeView](https://www.syncfusion.com/wpf-controls/treeview) (SfTreeview).
+
+You can create and manage the [TreeViewNode](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.TreeView.Engine.TreeViewNode.html) objects by yourself to display the data in a hierarchical view. To create a tree view, you use a `TreeView` control and a hierarchy of `TreeViewNode` objects. You create the node hierarchy by adding one or more root nodes to the SfTreeView.Nodes collection. Each `TreeViewNode` can have more nodes added to its Children collection. You can nest tree view nodes to whatever depth you require.
