我有一个出入库流水账，现在的代码是这样的：
Datacolchanged
Select Case e.DataCol.Name
Case "物料编号","入库数量","出库数量"
Dim dr As
DataRow
Dim mr As
DataRow = e.DataRow
Dim drs As
List(of DataRow)
dr =
e.DataTable.Find("[_SortKey] < " & mr("_SortKey")
& " And [物料编号] = '" & mr("物料编号") &
"'", "[_SortKey] Desc")
If dr Is
Nothing Then
mr("余数") = mr("入库数量") + mr("出库数量")
dr = mr
End If
drs =
e.DataTable.Select("[_SortKey] >= " & dr("_SortKey")
& " And [物料编号] = '" & dr("物料编号") &
"'", "[_SortKey]")
For i As
Integer = 1 To drs.Count - 1
drs(i)("余数") = drs(i-1)("余数") +
drs(i)("入库数量") + drs(i)("出库数量")
Next
If
e.DataCol.Name = "物料编号" AndAlso e.OldValue IsNot Nothing
AndAlso e.OldValue <> e.NewValue Then
dr = e.DataTable.Find("[_SortKey] <
" & mr("_SortKey") & " And [物料编号] = '" &
e.OldValue & "'", "[_SortKey] Desc")
If dr
Is Nothing Then
dr
= e.DataTable.Find("[物料编号] = '" & e.OldValue &
"'", "[_SortKey]")
If
dr IsNot Nothing Then
dr("余数") = dr("入库数量") + dr("出库数量")
End
If
End If
If dr
IsNot Nothing Then
drs
= e.DataTable.Select("[_SortKey] >= " &
dr("_SortKey") & " And [物料编号] = '" &
dr("物料编号") & "'", "[_SortKey]")
For
i As Integer = 1 To drs.Count - 1
drs(i)("余数") = drs(i-1)("余数") +
drs(i)("入库数量") + drs(i)("出库数量")
Next
End If
End If
End Select
Aftermoverow
Dim Key As Decimal
Dim Index As Integer
Dim Filter As String
Dim r As Row
Index = Math.Min(e.OldIndex, e.NewIndex)
Key = e.Table.Rows(Index)("_SortKey")
r = e.Table.Rows(e.NewIndex)
Filter = "[_SortKey]
>= " & Key & " And [物料编号] = '" &
r("物料编号")
& "'"
e.Table.DataTable.DataCols("入库数量").RaiseDataColChanged(Filter)
datarowdeleting
e.DataRow("入库数量") = 0
e.DataRow("出库数量") = 0
我的问题是，我在afteropenproject加了排序的代码，所以，待我完全进入系统之后，余数这栏的数据就不对了，也就是说，再也不像流水账了。我希望在对数据进行重新排序之后，流水账的余数也能自动发生变化，应该在哪里加些什么代码呢？
谢谢。
