+# Add WPF TreeView items by databinding in XML
+
+This session describes about how to add [WPF TreeView](https://help.syncfusion.com/wpf/classic/treeview/overview) (TreeViewAdv) items by databinding in XML.
+
+XML file can also be used as ItemsSource for the TreeViewAdv. The following example illustrates this:
+
+1. Create the XML file with the following details and name it as Data.xml:
+
+``` xml
+
+<Products>
+    <Product Name="Tools" >
+        <Feature Name="Ribbon" >
+            <Feature Name="Office2010UI"/>
+            <Feature Name="Data Binding Support"/>
+        </Feature>
+        <Feature Name="Docking Manager">
+            <Feature Name="Maximization"/>
+            <Feature Name="State Persistence"/>
+        </Feature>
+        <Feature Name="TreeView">
+            <Feature Name="Editing"/>
+            <Feature Name="Sorting"/>
+        </Feature>
+        <Feature Name="Data Editors" >
+            <Feature Name="Watermark Text" />
+            <Feature Name="Extended Value Scrolling" />
+        </Feature>
+    </Product>
+</Products>
+```
+
+2. Add the XmlDataProvider for the above XML document as follows:
+
+``` xml
+<Window.Resources>
+    <XmlDataProvider Source="Data.xml" x:Key="xmlSource" XPath="Products"/>
+</Window.Resources>
+```
+
+3. Set the `ItemsSource` property for the `TreeViewAdv` as follows:
+
+``` xml
+<syncfusion:TreeViewAdv ItemsSource="{Binding Source={StaticResource xmlSource}, XPath=Product}" >
+    <syncfusion:TreeViewAdv.ItemTemplate>
+        <HierarchicalDataTemplate ItemsSource="{Binding XPath=Feature}">
+            <TextBlock Text="{Binding XPath=@Name}" />
+        </HierarchicalDataTemplate>
+    </syncfusion:TreeViewAdv.ItemTemplate>
+</syncfusion:TreeViewAdv>
+```
+
+4. `TreeViewAdv` will be created as follows:
