To stop the selection bar on a data-bound grid from moving when navigating through records in the bound RDC or the rows on the grid, use the API call LockWindowUpdate(gridname.hwnd) before navigating the record pointer, and LockWindowUpdate(0) after the navigation:

 
'Declarations Section
#If Win32 Then
        Declare Function LockWindowUpdate _
                Lib "user32" _
                (ByVal hwndLock As Long) As Long
#Else
        Declare Function LockWindowUpdate _
                Lib "User" _
                (ByVal hwndLock As Integer) _
                As Integer
#End If

Private Sub cmdHideSelector_Click()
        LockWindowUpdate DBGrid1.hWnd
End Sub

Private Sub cmdShowSelector_Click()
        LockWindowUpdate 0
End Sub
