namespace TestHover29282
{
    public partial class Window1 : Window
    {
        public Window1()
        {
            InitializeComponent();

            TextBlock tb = new TextBlock();
            tb.Text = "Jim Smith";

            ToolTip tt = new ToolTip();
            tt.Content = "This is some info on the customer.";

            tb.ToolTip = tt;

            //ToolTipService tts = new ToolTipService();
            //tts.Duration = 0;
            //tb.ToolTipService = tts;

            MainStackPanel.Children.Add(tb); 
        }
