tooltip

Hello, I'd like to show a tooltip when I move the mouse. Here is my code:

 private void Grid_MouseMove(object sender, MouseEventArgs e)
        {
            Grid grid = (Grid) sender;
            if (e.GetPosition(grid).X < 100)
                grid.ToolTip = e.GetPosition(grid).X.ToString();
            else
                grid.ToolTip = null;
        }

However, the tooltip disappears after I click on the grid.

Is there a way to force showing the tooltip?
