Is there a add text markup tool for silverlight?

[YingLin]

I am looking for a tool that can allow user to add custom text to the map and then create custom map in silverlight. I have graphic tools for adding polygon, rectangle, freehand graphics but didn't see one for adding text. Maybe i missed. Any one can point me out where i can find the tool?
THanks very much

Hi,

I can't make this work. I have a tool, I can add text boxes, edit them but they won't appear on my printed map (using ArcGIS server printing).

How is Binding supposed to work?
<TextBox Text="{Binding Attributes[MyAttribute], Mode=TwoWay, TargetNullValue=Null}"/>

How do I clone graphics using clonedGraphic.Attributes.Add(o.key, _mytext)?

Thanks a lot for your help.
