+This example illustrates to bind the `SelectedItem` property from ViewModel to the [SelectedItem](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Grid.SfGridBase.html#Syncfusion_UI_Xaml_Grid_SfGridBase_SelectedItem) Property of [WPF TreeGrid](https://www.syncfusion.com/wpf-controls/treegrid) and [UWP TreeGrid](https://www.syncfusion.com/uwp-ui-controls/treegrid).
+
+You can bind the `SelectedItem` property directly to `TreeGrid` by setting the [SfTreeGrid.SelectedItem](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Grid.SfGridBase.html#Syncfusion_UI_Xaml_Grid_SfGridBase_SelectedItem) property.

+## XAML code:
+
+``` xml
+<syncfusion:SfTreeGrid Name="treeGrid" 
+                               Grid.Row="1" 
+                               ChildPropertyName="ReportsTo"  
+                               AutoExpandMode="AllNodesExpanded"
+                               ShowRowHeader="True" 
+                               SelectedItem="{Binding SelectedItem, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
+                               AutoGenerateColumns="False"
+                               ItemsSource="{Binding Employees}"
+                               ParentPropertyName="ID"
+                               SelfRelationRootValue="-1"/>
+
+```
+
+## C# code:
+
+``` C#
+public class ViewModel: NotificationObject
+{
+    private object selectedItem;
+    public object SelectedItem
+    {
+        get
+        {
+           return selectedItem;
+        }
+        set
+        {
+           selectedItem = value;
+           RaisePropertyChanged("SelectedItem");
+        }
+    }
+}
