How to style open file dialog box in Silverlight

I am not an SL developer myself, but before I invest in it, I want to make sure I get its capabilities and limitations. My question is is it possible to style (i.e. change the UI of) an open file dialog box? It开发者_StackOverflow中文版 would be nice to see a sample if possible.

I don't think that you can do that. You have no chance to change the title, or preset a path either. (http://msdn.microsoft.com/en-us/library/system.windows.controls.openfiledialog(v=vs.95).aspx, Is there anyway to change title of OpenFileDialog in Silverlight 3?)
