红版 datacolchanged的事件代码能不能放到按键上实行

Select Case e.DataCol.name
    Case "司机", "车牌", "出车日期","项目","城市","客户","车型","地点"
        Dim filter As String = "司机 = '" & e.DataRow("司机") & "' and 车牌 = '" & e.DataRow("车牌") & "' and 出车日期 = #" & e.DataRow("出车日期") & "#"
        Dim drs As List(of DataRow) = e.DataTable.Select(filter)
        For Each dr As DataRow In drs
            If DataTables("价目表").DataCols.Contains("车型_" & e.DataRow("车型")) Then
                Dim jdrs As List(of DataRow) = DataTables("价目表").Select("项目 like '%" & e.DataRow("项目") & "%' and 城市 like '%" & e.DataRow("城市") & "%'")
                For Each jdr As DataRow In jdrs
                    If e.DataRow("地点") Like "*" & jdr("地点") & "*" Then
                        e.DataRow("运费") = jdr("车型_" & e.DataRow("车型"))
                        Exit For
                    End If
                Next
            End If
        Next
        drs = e.DataTable.Select(filter, "运费 desc")
        For i As Integer = 0 To drs.Count - 1
           
            Select Case drs(i)("车型")
                Case "9M6"
                    drs(i)("点费") = 80
                Case "6M2","6M8","7M6"
                    drs(i)("点费") = 60
                Case "4M5","4M2"
                    drs(i)("点费") = 30
            End Select
           
            If i = 0 Then
                drs(i)("点费") = Nothing
            Else
                drs(i)("运费") = Nothing
            End If
        Next
        For Each str As String In e.DataTable.GetValues("送货地址", filter)
            drs = e.DataTable.Select(filter & " and 送货地址 = '" & str & "'")
            For i As Integer = 0 To drs.Count - 1
                If i > 0 Then
                    drs(i)("点费") = Nothing
                End If
            Next
        Next
End Select

计算运费与点费的  并且单击值计算当前表 比如目录树筛选出某个司机的订单 按下按键 只计算当前司机的运费和点费
