How to create Dash Dot Dot Border for custom fill symbol?

[RomanGeoda]

I would like to make a brush with a style of "dash dot dot" in silverlight.
I actually want to accomplish a "dash dot dot" border around a custom graphic (apply it to a FillSymbol.BorderBrush property). Is there a way to do this?

Thanks,
Roman.

You can get the result you are expecting by using a CartographicLineSymbol and setting the DashArray.
You will find samples in the symbol gallery : http://help.arcgis.com/en/webapi/silverlight/samples/SymbolGalleryWeb/start.htm

And if you have not seen it there is not better example of creating custom symbology than Dominques http://www.arcgis.com/home/item.html?id=1e432da7e74f4402bd43a5863167022d#

Thank you for your help.
I'll have a look at these two links. Looks very promising!
