Why I can view only first 418 records from .MDB when using MS DataGrid+MS Adodc?

I have created a MFC project, based on Microsoft ADO Data Control and Microsoft
DataGrid Control to work with Microsoft Access databases. But when i connects Adodc to .MDB and binds with DataGrid,
there are only first 418 records from database table appears in the grid instead
of 600. Please, help me understand what's wrong here.

This is initialization function for Adodc (m_ctlADODC defined in CMyADODCViev
class as "public CAdodc m_ctlADODC;"):

And this is for DataGrid (m_pGrid defined in CMainFrame class as
"public: CDataGrid* m_pGrid;", it creates during CMainFrame initialization).
