 # how-to-sort-the-TreeView-node-in-SfTreeView
-This project contains the source code for the Chat control in .NET WPF, Winforms, and WinUI platforms.
+This repository demonstrates how to sort the treeview nodes in SfTreeView.
+
+## Sample
+
+### XAML
+
+```xaml
+        <Button Text="Sort TreeView" Command="{Binding TreeViewSortCommand}" HeightRequest="50" Grid.Row="0" />
+        <syncfusion:SfTreeView x:Name="treeView" Grid.Row="1" ChildPropertyName="SubFiles" ItemTemplateContextType="Node" AutoExpandMode="AllNodesExpanded" ItemsSource="{Binding ImageNodeInfo}">
+            <syncfusion:SfTreeView.ItemTemplate>
+                <DataTemplate>
+                    <Grid x:Name="grid" RowSpacing="0" >
+                        <Grid.ColumnDefinitions>
+                            <ColumnDefinition Width="40" />
+                            <ColumnDefinition Width="*" />
+                        </Grid.ColumnDefinitions>
+                        <Image Source="{Binding Content.ImageIcon}" VerticalOptions="Center" HorizontalOptions="Center" HeightRequest="35" WidthRequest="35"/>
+                        <Grid Grid.Column="1" RowSpacing="1" Padding="1,0,0,0" VerticalOptions="Center">
+                            <Label LineBreakMode="NoWrap" Text="{Binding Content.ItemName}" VerticalTextAlignment="Center"/>
+                        </Grid>
+                    </Grid>
+                </DataTemplate>
+            </syncfusion:SfTreeView.ItemTemplate>
+        </syncfusion:SfTreeView>
+```
+### View Model
+
+```csharp
+   public class FileManagerViewModel : INotifyPropertyChanged
+    {
+        #region Fields
+
+        private ObservableCollection<FileManager> imageNodeInfo;
+
+        #endregion
+
+        #region Constructor
+
+        public FileManagerViewModel()
+        {
+            TreeViewSortCommand = new Command(OnTreeViewSortClicked);
+            GenerateSource();
+        }
+
+        #endregion
+
+        #region Properties
+
+        public ObservableCollection<FileManager> ImageNodeInfo
+        {
+            get
+            {
+                return imageNodeInfo;
+            }
+            set
+            {
+                this.imageNodeInfo = value;
+                this.RaisedOnPropertyChanged("ImageNodeInfo");
+            }
+        }
+
+        public Command TreeViewSortCommand { get; set; }
+
+        #endregion
+
+        #region Command method
+
+        private void OnTreeViewSortClicked(object obj)
+        {
+            this.ImageNodeInfo = new ObservableCollection<FileManager>(ImageNodeInfo.OrderBy(i => i.ItemName));
+        }
+}
+```
