graphic tooltip?

Question

Using Flex Builder, I can set a graphic tooltip like that:
   myGraphic.toolTip = "my tooltip"; 
In SL, I cannot find the tooltip property, but see graphic.MapTip.  Does anyone knows how to set a tooltip value for SL application?  Thanks.

I think you have the same problem you've had as in your other posts where your map and UserControl are separate.  I have already suggested creating a DependencyProperty in your UserControl so that it can have its own map source that gets set in your MainPage when you create an instance of it.

You need not duplicate the contents of your map in the MainPage to your UserControl - this approach will not work, because they will be dealing with two different maps.

Try to solve one problem at a time. You will see what works in one and learn from it. Good luck.

Thanks to both for your responses. I did review and tried the code before, but not successful. In my scenario, the tooltip is applied to a usercontrol tool. In the usercontrol's xaml, ...

In the C# file, GraphicsLayer graphicsLayer = _Map.Layers["MyGraphicsLayer"] as GraphicsLayer; MyMapTip.GraphicsLayer = graphicsLayer; Also the usercontrol's _Map is set the same as the MainPage's MyMap in MainPage.xaml.cs: myUserControl.SetMap(this.MyMap); in the C# file, by: public void SetMap(Map TheMap); { _Map = TheMap; } Is there anything wrong in my coding? Thanks.
