Remarks

UXTreeViewItem implements ICommandSource interface which exposes Command, CommandParameter and CommandTarget property. You can assign a command to a UXTreeViewItem by setting its Command property to the target command existed in your application. With commanding, you can separate the actual logic of the command from the command definition, which is ideal for MVVM pattern application. To learn about MVVM pattern, see MVVM Pattern Overview.

For more information on how to implement routed command in your application, see How-to: Implement a RoutedCommand. For more information about the basics of commanding concept, see Commanding Overview.

Depending on the scenarios you want to achieve, you may want to evaluate when to use command or selection in your application. It's best practice to use commanding when you have a particular action to execute when a node is selected. However, if you simply wish to capture the current selection in the control, please use the SelectedItem or SelectedItems property.
