+# How to Bind Column ItemsSource from ViewModel in WPF / UWP TreeGrid in MVVM?
 
-This example illustrates to bind the ComboBox column ItemsSource using MVVM.
\ No newline at end of file
+This example illustrates how to bind the ComboBox column's **ItemsSource** using MVVM in [WPF TreeGrid](https://www.syncfusion.com/wpf-controls/treegrid) / [UWP TreeGrid](https://www.syncfusion.com/uwp-ui-controls/treegrid) (SfTreeGrid).
+
+You can bind the **ItemsSource** from ViewModel to [TreeGridComboBoxColumn](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.TreeGrid.TreeGridComboBoxColumn.html) or using **ElementName** binding.
+
+### XAML:
+
+``` xml
+<syncfusion:TreeGridComboBoxColumn AllowEditing="True" 
+                                   MappingName="Title"
+                                   HeaderText="Title"
+                                   ItemsSource="{Binding DataContext.TitleList,
+                                                ElementName=treeGrid}" />
+```
+
+### C# ViewModel:
+``` c#
+private ObservableCollection<string> titleList;
+
+public ObservableCollection<string> TitleList
+{
+     get { return titleList; }
+     set { titleList = value; }
+}
+```
