Quick question - Is it possible to automate tests against non-standard .NET WPF controls (example: Xceed grids) using the Extern object / Declare method?

QTP cannot handle these controls out of the box. One of our developers is able to write C# or VB.NET code that can access and manipulate these non-standard controls using hooks into Microsoft UI Automation.

Would it be possible to access these grids by using Extern/Declare to call these .dlls during script execution?
