+# How to Bind the SelectedItem Property of WPF TreeGrid in MVVM?
 
-This example illustrates to bind the SelectedItem property from ViewModel to treegrid.
+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) (SfTreeGrid).
+
+You can bind the **SelectedItem** property directly to TreeGrid by setting the **SfTreeGrid.SelectedItem** property.
+
+### XAML:
+
+``` 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#:
+
+``` C#
+public class ViewModel: NotificationObject
+{
+    private object selectedItem;
+
+    public object SelectedItem
+    {
+        get
+        {
+           return selectedItem;
+        }
+        set
+        {
+           selectedItem = value;
+           RaisePropertyChanged("SelectedItem");
+        }
+    }
+}
+```
