销售接单表想直接引用发货表的部分列，麻烦老师看下我写的代码错在那里

Dim Cols1() As String = {"车型", "车辆来源", "凭证号", "发货日期"}

Dim Cols2() As String = {"车型", "车辆来源", "凭证号", "发货日期"}

Dim dr As DataRow

dr = DataTables("发货表").Find("[接单单号] = '" & e.NewValue & "'")

Dim Filter As String = "[接单单号] = '" & e.DataRow("接单单号") & "'"

Dim drs As List(Of DataRow) = DataTables("销售接单").Select(Filter)

For Each dr As DataRow In drs

For i As Integer = 0 To Cols1.Length - 1

dr(Cols2(i)) = drs(Cols1(i))

datacolchanged事件？参考：http://www.foxtable.com/webhelp/topics/1451.htm

If e.DataCol.Name = "接单单号" Then '如果内容发生变动的是品名列

Dim Cols1() As String = {"车型", "车辆来源", "凭证号", "发货日期"}
If e.NewValue Is Nothing Then '如果新值是空白,也就是品名列的内容为空

For i As Integer = 0 To Cols1.Length - 1

e.DataRow(Cols1(i)) = Nothing

    Else
        Dim dr As DataRow
        '否则在产品表查找同名的产品行,将找到的行赋值给变量dr
        dr = DataTables("产品").Find("[接单单号] = '" & e.NewValue & "'")
        If dr IsNot Nothing Then '如果找到了同名的产品行,也就是dr不是Nothing

For i As Integer = 0 To Cols1.Length - 1

e.DataRow(Cols1(i)) = dr(Cols1(i))

End If
End If
End If

我先有销售接单表，也就是说我想在发货表填了四项内容后，能即时填到销售接单表中

发货表datacolchanged事件

Select Case e.DataCol.Name
Case "车型", "车辆来源", "凭证号", "发货日期"
Dim Filter As String = "[接单单号] = '" & e.DataRow("接单单号") & "'"

For i As Integer = 0 To Cols1.Length - 1
DataTables("销售接单表").ReplaceFor(Cols1(i), e.DataRow(Cols1(i)), Filter)

next
End Select
