Dim Cols1() As String = {"登记号","计划号","物料ID","物料名称","物料名称日文","规格型号","请购数量","下单数量","含税单价","希望到货日期","供应商名"}

For Each dr1 As Row In Tables("比价生单窗口_Table1").GetCheckedRows

Dim result As DialogResult

If result = False Then

For i As Integer = 1 To Tables("比价生单窗口_Table1").Rows.Count

Dim dr As Row

dr = Tables("比价生单窗口_Table1").Rows(i)

If dr("下单数量") > dr("剩余数量") Or dr("下单数量") < 0 Then

messagebox.show("下单数量不能大于请购数量或小于'0'!")

End If

Dim dr2 As Row = Tables("orderList").AddNew()

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

dr2(Cols2(i)) = dr1(Cols1(i))
