主题：不自动编号

你好，做了个自动编号列，结果是第一行有自动编号，第二行就不编了。做法是根据“piao号“自动“编号“。代码如下（帮助文件复制的）：

Select e.DataCol.Name
    Case "类别"
        If e.DataRow.IsNull("类别") Then
            e.DataRow("编号") = Nothing
        Else
            Dim lb As String = e.DataRow("类别")
            If e.DataRow("编号").StartsWith(lb) = False '如果单据编号前缀不符
                Dim max As String
                Dim idx As Integer
                max = e.DataTable.Compute("Max(编号)","类别 = '" & lb & "' And [_Identify] <> " & e.DataRow("_Identify")) '取得该类别的最大编号
                If max > "" Then '如果存在最大编号
                    idx = CInt(max.Substring(2,3)) + 1 '获得最大编号的后三位顺序号,并加1
                Else
                    idx = 1 '否则顺序号等于1
                End If
                e.DataRow("编号") = lb & Format(idx,"000")
            End If
        End If
End Select

Select e.DataCol.Name
    Case "类别"
        If e.DataRow.IsNull("类别") Then
            e.DataRow("编号") = Nothing
        Else
            Dim lb As String = e.DataRow("类别")
            If e.DataRow("编号").StartsWith(lb) = False '如果单据编号前缀不符
                Dim max As String
                Dim idx As Integer
                max = e.DataTable.Compute("Max(编号)","类别 = '" & lb & "' And [_Identify] <> " & e.DataRow("_Identify")) '取得该类别的最大编号
                If max > "" Then '如果存在最大编号
                    idx = CInt(max.Substring(lb.length,3)) + 1 '获得最大编号的后三位顺序号,并加1
                Else
                    idx = 1 '否则顺序号等于1
                End If
                e.DataRow("编号") = lb & Format(idx,"000")
            End If
        End If
End Select

 

谢谢，问题解决
