How to clear current selections by code

Hi experts,

I have a PropertyManager page with multiple selection box, with select same type (SolidBody).

If I use IModelDoc2::ClearSelection2 to clear selection, it will clear all selections in other selection box of this PropertyManager page. So, what should I do to clear selections in only the selection box which I want (current selection box, maybe)?

Thanks for reading!

Best regards,

Kieu Tran.
