If e.DataCol.Name = "入库日期" Then
If e.DataRow.IsNull("入库日期") Then
e.DataRow("入库明细单号") = Nothing
Else
Dim d As Date = e.DataRow("入库日期")
Dim y As Integer = d.Year
Dim m As Integer = d.Month
Dim Days As Integer = Date.DaysInMonth(y, m)
Dim fd As Date = New Date(y, m, 1) '获得该月的第一天
Dim ld As Date = New Date(y, m, Days) '获得该月的最后一天
Dim bh As String = Format(d, "yyyyMM") '生成编号的前6位,4位年,2位月.
If e.DataRow("入库明细单号").StartsWith(bh) = False Then'如果编号的前6位不符
Dim max As String
Dim idx As Integer
max = e.DataTable.Compute("Max(入库明细单号)", "入库日期 >= #" & fd & "# And 入库日期 <= #" & ld & "# And [_Identify] <> " & e.DataRow("_Identify")) '取得该月的最大编号
If max > "" Then '如果存在最大编号
idx = CInt(max.Substring(11, 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("入库明细单号") = "RKMX" & bh & "-" & Format(idx, "000")
End If
End If
End If
明细表新增时,不是相同主表里新增数据时入库明细单号不连之前的号,之前有001,002号,新增时从001号重新开,正确的是003
