主题：[求助]批量复制

谢谢狐爸，不过这种做法并没有解决复制对应明细的功能呀。原先复制明细是用新增行的订单号做为条件复制的，现在订单号为空，若还要订单号做为条件复制该怎么做呢？？

这样就可以了：

Dim r1 As Row = Tables("办单信息").Current
Dim r2 As Row = Tables("办单信息").AddNew
For Each c As Col In Tables("办单信息").Cols
    If c.name <> "PO号" Then
        r2(c.name) = r1(c.name)
    End If
Next
Dim val As String =DataTables("办单信息").Compute("Max(PO号)")
val = val.SubString(2)
r2("PO号") = "R-" & cint(val+1)
For Each dr1 As DataRow In r1.DataRow.GetChildRows("办单物料明细表")
    Dim dr2 As DataRow = DataTables("办单物料明细表").AddNew()
    For Each dc As DataCol In DataTables("办单物料明细表").DataCols
        If dc.name <> "办单号" Then
            dr2(dc.name) = dr1(dc.name)
        End If
        dr2("办单号") = r2("PO号")
    Next
Next

谢谢狐爸，问题解决了；
