PreTranslateMessage is not called in CMessageFilter and CEdit derived class

Maybe this question has been answered somewhere on forums, but I could not find. Basically, I want to filter chars in the in-place edit box to allow entering only digits (for integer). I thought that PreTranslateMessage can help, but the method is never called. My in-place control is derived as:

class CMyInPlaceEdit
	: public CWindowImpl<CMyInPlaceEdit, CEdit>
	, public CMessageFilter
	, public CUpdateUI<CMyInPlaceEdit>
{
public:
    DECLARE_WND_SUPERCLASS(_T("inplaceEdit"), CEdit::GetWndClassName())

    virtual BOOL PreTranslateMessage(MSG* pMsg);
...

Please help...
