主题：数据不自动改变

我在参数表中改娈材料单价，盘具成本表中的单价不自动改变，是不是代码有问题，请师傅帮助修正。

你的代码放在哪里?

提出这个问题，说明你还没有理解这段代码。这代代码设置在盘具成本表，目的是输入某个品种和规格后，从参数表取得单价并自动输入，代码的任务仅此而已。

如果要修改参数表，盘具成本表的单价也一起变动，请参考： 

http://help.foxtable.com/topics/1453.htm

我的代码放在：DataColChanged 里，根据狐狸师傅的提示，进行了重写测试，没有成功，可能是我写错，还是请师傅根据上面提供的代码帮助重写，谢谢师傅。

 

贴出你重写的代码来看看。

If e.DataCol.Name = "型钢_单价"
    Dim Filter As String ="[品种] = '" & e.DataRow("盘具品种") & "'And [型钢_规格] = '" & e.DataRow("钢材规格") & "'"
    Dim drs As List(Of DataRow) = DataTables("参数").Select(Filter)
    For Each dr As DataRow In drs
        dr("型钢_单价") = e.DataRow("钢材单价")
    Next
End If
盘具品种、钢材规格、钢材单价是参数表里的，要求是参数表里钢材单价改变，成本表里输入相对应村材料的单价也要改变

If e.DataCol.Name = "钢材单价" Then
    Dim Filter As String ="[品种] = '" & e.DataRow("盘具品种") & "'And [型钢_规格] = '" & e.DataRow("钢材规格") & "'"
    Dim drs As List(Of DataRow) = DataTables("盘具成本").Select(Filter)
    For Each dr As DataRow In drs
        dr("型钢_单价") = e.DataRow("钢材单价")
    Next
End If

为什么还是没有反映

还是请师傅帮我分析呀

 

 

列有没有刷新过.
