The following example shows how to assign an event handler for the Selected event to a TreeViewItem, and how to define the event handler.

<TreeViewItem Header="Employee2" 
              Name="Employee2Data">
  <TreeViewItem Header="Work Days" 
                Name="emp2WorkDays" 
                Selected="GetSchedule"
                Unselected="SetSchedule">
    <TreeViewItem Header="Monday" />
    <TreeViewItem Header="Wednesday"/>
  </TreeViewItem>
private void SetSchedule(object sender, RoutedEventArgs e)
{
    //Perform actions when a TreeViewItem 
    //control becomes unselected
