流水帐中要区分 帐户
DataColChanged事件为:
Select Case e.DataCol.Name
Case "金额","收付"
Dim dr As DataRow
Dim drs As List(of DataRow)
dr = e.DataTable.Find("[_SortKey] < " & e.DataRow("_SortKey"), "[_SortKey] Desc") \'找出上一行
If dr Is Nothing Then \'如果没有找到上一行,说明本行就是第一行
If e.DataRow("收付") = "收" Then
e.DataRow("帐户余额") = e.DataRow("金额")
End If
If e.DataRow("收付") = "付" Then
e.DataRow("帐户余额") = -e.DataRow("金额")
End If
dr = e.DataRow
End If
MessageBox.Show(dr("帐户"))
drs = e.DataTable.Select("[_SortKey] >= " & dr("_SortKey") & " And [帐户] = " & dr("帐户") & "" ,"[_SortKey]")
For i As Integer = 1 To drs.Count - 1 \'重算余下行的余额
If drs(i)("收付") = "收" Then
drs(i)("帐户余额") = drs(i-1)("帐户余额") + drs(i)("金额")
End If
If drs(i)("收付") = "付" Then
drs(i)("帐户余额") = drs(i-1)("帐户余额") - drs(i)("金额")
End If
Next
End Select
