that's true .... renderer its null.
it's wrong the way to set the renderer ?

The Renderer can be set this way but it needs to be defined in the resources. 
In your case, it looks like the "DefaultFillRenderer" is not defined in the resources of the Layout grid.

dyn_ftlyr.ID = "MyUrl";

I guess it's just a typo and that you are initializing the Url method and not the ID
 dyn_ftlyr.Renderer = LayoutRoot.Resources["DefaultFillRenderer"] as SimpleRenderer ;

Did you verify in debug that the renderer is not null?
