我前面的销售单，退货单，进货单，也都设置了表属性DataColChanged事件代码，主要是希望，前面基础信息表的客户名称那些有添加新的名称或者修改，这里也可以实时更新，代码您帮我看看
If e.DataCol.Name = "客户编号" Then '如果内容发生变动的是品名列
If e.NewValue Is Nothing Then '如果新值是空白,也就是品名列的内容为空
e.DataRow("客户") = Nothing '那么清空此行单价列的内容
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("客户信息").Find("[客户编号] = '" & 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
e.DataRow("客户") = dr("客户")
End If
End If
End If
If e.DataCol.Name = "商品编号" Then
If e.NewValue Is Nothing Then
e.DataRow("商品名称") = Nothing
e.DataRow("规格") = Nothing
e.DataRow("单位") = Nothing
e.DataRow("型号") = Nothing
e.DataRow("单价") = Nothing
Else
Dim dr As DataRow
dr = DataTables("商品信息").Find("[商品编号] = '" & e.NewValue & "'")
If dr IsNot Nothing
e.DataRow("商品名称") = dr("商品名称")
e.DataRow("型号") = dr("型号")
e.DataRow("规格") = dr("规格")
e.DataRow("单位") = dr("单位")
e.DataRow("单价") = dr("单价")
End If
End If
End If
Select Case e.DataCol.Name
Case "商品名称","型号","规格","单位"
Dim Filter As String = "[商品编号] = '" & e.DataRow("商品编号") & "'"
DataTables("退货单").ReplaceFor(e.DataCol.Name, e.NewValue, Filter)
End Select
Select Case e.DataCol.Name
Case "客户"
Dim Filter As String = "[客户编号] = '" & e.DataRow("客户编号") & "'"
DataTables("退货单").ReplaceFor(e.DataCol.Name, e.NewValue, Filter)
End Select
