老师，下面的代码是按钮里的，帮我看看有什么问题，没有反应？
Dim Cols1() As String = {"订单明细编号对外","客户","品名大类","品名小类","坯布规格","缸号类型","投坯重量","投坯匹数","颜色","单双染","色号","卡注"}
Dim Cols2() As String = {"订单明细编号对外","客户","品名大类","品名小类","坯布规格","缸号类型","重量","匹数","颜色","单双染","色号","卡注"}
If Tables(e.Form.Name & "_table3").Rows.Count > 0 Then
    For Each r1 As Row In Tables(e.Form.Name & "_table3").Rows
        Dim dr1s As List(of DataRow) = DataTables("染色生产表").SQLSelect("缸号 = \'" & r1("缸号") & "\'")
        If dr1s.Count > 0 Then
            For Each dr1 As DataRow In dr1s
                For i As Integer = 0 To Cols1.Length -1
                    dr1(Cols2(i)) = r1(Cols1(i))
                Next
                dr1.Save
            Next
        End If
    Next
End If

 你要学会调试啊。

 

 加入msgbox，看是否进入判断里面了？如果没有进入，说明没有查询到对应的内容。

老师，后来代码改成这样了，也达到预期作用，但是初学者，没有信心，看代码有没有改进的地方，谢谢？
If Tables(e.Form.Name & "_table3").Rows.Count > 0 Then
    Dim tj As String
    For Each r As Row In Tables(e.Form.Name & "_table3").Rows
        tj = "\'" & r("缸号")  & "\'," & tj
    Next
    tj = tj.TrimEnd(",")
    DataTables("染色生产表").LoadFilter = "缸号 in (" & tj & ")"
    DataTables("染色生产表").Load

3楼的方式，比你原先的重复sqlSelect要好。
