主题：求筛选后合计代码

在“销售明细”表窗口，“筛选并合计”按钮是模糊筛选，输入关键字后，点击该按钮，会筛选所要的记录。要求能将筛选的结果最后加一行合计，对筛选出的数量和金额合计。请师傅帮忙，谢谢！

对主表进行合计还是DataList控件？

不好意思，发帖后有事去了。
我想最好两个都要，不行就Datalist吧,谢谢先生关心！

筛选并合计按钮代码：

Dim Filter As String = ""
Dim Val As String = Forms("窗口2").Controls("TextBox1").Value
if Val is nothing then
    MessageBox.Show("对不起,请先输入查找内容!", "提示")
Else
    For each c As col In CurrentTable.Cols
        If c.IsString Then
            If Filter > "" Then
                Filter = Filter & " Or "
            End If
            Filter = Filter &  c.Name & " Like '*" & Val & "*'"
        End If
    Next
    CurrentTable.Filter = Filter
   
    if CurrentTable.Rows.Count-1 >= 0 Then
        Dim t As Table = Tables("销售明细")
        Dim g As SubtotalGroup
        t.SubtotalGroups.Clear()
        t.GroupAboveData = False
        t.TreeVisible = False
        g = New SubtotalGroup
        g.Aggregate = AggregateEnum.Sum
        g.GroupOn = "*"
        g.TotalOn = "数量,金额"
        g.Caption = "总计"
        t.SubtotalGroups.Add(g)
        t.Subtotal()
       
        Dim dst1 As WinForm.DataList = Forms("窗口2").Controls("DataList1")
        dst1.ColumnList=("ID|日期|年|月|日|商品名称|规格|单位|数量|金额|客户|经手人")
        dst1.Filter = CurrentTable.Filter
        dst1.DataTable = DataTables("销售明细")
        dst1.Build()
        dst1.GrandTotal(AggregateEnum.Sum,"合计","数量","金额")
       
    Else
        MessageBox.Show("对不起,没有符合条件的数据!", "提示")
    End If
end if

谢谢您，八婺老师！我慢慢琢磨去。
