+
+This repository describes how to bind selected items in WPF TreeView (SfTreeView).
+
+TreeView support to select multiple items through binding the [SelectedItems](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.TreeView.SfTreeView.html#Syncfusion_UI_Xaml_TreeView_SfTreeView_SelectedItems) property from view model with `ObservableCollection<object>` type.
+
+#### XAML
+
+``` xml
+<syncfusion:SfTreeView 
+            x:Name="sfTreeView"
+            SelectionMode="Multiple"
+            SelectedItems="{Binding SelectedNodes}"   
+            ChildPropertyName="Models"
+            ItemsSource="{Binding Items}" >
+</syncfusion:SfTreeView>
+```
+
+#### C#
+
+``` csharp
+sfTreeView.SelectionMode = SelectionMode.Multiple;
+sfTreeView.SetBinding(SfTreeView.SelectedItemsProperty, new Binding("SelectedNodes"));
+```
+
+``` csharp
+public class ViewModel : NotificationObject
