Apparently MapTip has a GraphicsLayer property, and a GraphicsLayer has a MapTip property.
When I use the MapTip class placed in my XAML, and set its GraphicsLayer property to some Graphic or Feature layer, then I get a cool comic strip-style balloon, but it only shows the Title on mouse hover, and the various attributes you added to the graphic layer on mouse-click.
When I use the MapTip property of a GraphicsLayer, I can define my own content, but I don't get the cool balloons.
Is there any way to get the cool dialog balloons, but still be able to define the content inside of the balloon by my own template?
