According to MSDN:

"Call OpenThemeData and pass the hwnd of the control you wish to apply
visual styles to and a class list that describes the control's type. The
classes are defined in Tmschema.h. OpenThemeData returns an HTHEME handle,
but if the visual style manager is disabled or the current visual style does
not supply specific information for a given control, the function returns
NULL."

Exactly.  You are trying to load a theme element that does not actually
exist for TStringGrid.

You assume incorrectly.

Then you are not using it properly to begin with.  Please show your actual
code.
