How can I do this?

Hi Jon,

 In order to achieve your goal I suggest you to subscribe to the RadComboBox's SelectionChanged event like so:

public MainWindow()
       {
           InitializeComponent();

           this.AddHandler(RadComboBox.SelectionChangedEvent, new System.Windows.Controls.SelectionChangedEventHandler(OnSelectionChanged));
       }


       private void OnSelectionChanged(object sender, System.Windows.Controls.SelectionChangedEventArgs e)
       {
           string selectedItem = string.Empty;
           if (e.RemovedItems.Count>0 && e.AddedItems.Count > 0)
           {
               selectedItem = e.AddedItems[0].ToString();
               txtSelectedValue.Text = selectedItem;
               MessageBox.Show(selectedItem);
           }
       }

For your convenience I have attached prepared a sample project. Please find it attached.
