+# How to Bind Button Command to ViewModel in WPF / UWP TreeGrid in MVVM?
 
-This example illustrates to bind the button command to ViewModel in treegrid.
+This example illustrates to bind the Button command to ViewModel in [WPF TreeGrid](https://www.syncfusion.com/wpf-controls/treegrid) and [UWP TreeGrid](https://www.syncfusion.com/uwp-ui-controls/treegrid) (SfTreeGrid).
+
+You can load a button for the columns in TreeGrid using [TreeGridTemplateColumn](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.TreeGrid.TreeGridTemplateColumn.html). When loading the buttons, you can bind a command in ViewModel using ElementName binding.
+
+In the following example, ViewModel command receives the underlying data object as command parameter, since the DataContext is bound as command parameter.
+
+### XAML:
+``` xml
+<syncfusion:TreeGridTemplateColumn MappingName="Title" 
+                                   syncfusion:FocusManagerHelper.WantsKeyInput="True">
+       <syncfusion:TreeGridTemplateColumn.CellTemplate>
+           <DataTemplate>
+               <Button  Content="Click" syncfusion:FocusManagerHelper.FocusedElement="True" 
+                        Command="{Binding Path=DataContext.RowDataCommand,ElementName=treeGrid}" 
+                        CommandParameter="{Binding}"/>
+           </DataTemplate>
+       </syncfusion:TreeGridTemplateColumn.CellTemplate>
+</syncfusion:TreeGridTemplateColumn>
+```
