Custom ResourceProvider with a fallback for standard ASP.NET localization mechanism

Hi,
I wrote my own custom ResourceProvider in order to move localization management to DB instead using standard resx files.
The provider works fine, but now (after having bought a third part components for UI) I need to implement a fallback to standard ASP.NET localization mechanism from my own provider since these controls has been already localized from the author and are packaged with resx files.
So what I would like to do, is keep the actual mechanism for all the resources except for the resoucers related to this controls.
I'm able to distinct when a resource is belong to external components, so what I need is how to invoke for this resource the standard location management.
 
Thanks
