标题：按时间段加载问题

老师，我用下面的代码实现了按日期时间段显示，是先全部加载再筛选显示；我想实现的是不全部加载，按时间段加载。请您指导。
With DataTables("创新活动表")
.loadtop = Nothing
.loadfilter = ""
.load()
End With
Dim Filter As String

With e.Form.Controls("DateTimePicker1")
    If .Value IsNot Nothing Then
        If Filter >"" Then
            Filter = Filter & " And "
        End If
        Filter = Filter & "日期 >= #" & .Value & "#"
    End If
End With
With e.Form.Controls("DateTimePicker2")
    If .Value IsNot Nothing Then
        If Filter >"" Then
            Filter = Filter & " And "
        End If
        Filter = Filter & "日期 <= #" & .Value & "#"
    End If
End With

If Filter > "" Then
Tables("创新活动表").Filter = Filter
End If
