合并审理的案件数量怎样计算？

谢谢！

怎样把count的最终值赋值给[案件数量]列呢？

现在是把每次循环的值赋值给当前行，我想给每行都赋值为最终值。

Select Case e.DataCol.Name
    Case "合并审理","原告出庭","被告出庭"
        Dim str As String = e.DataRow("合并审理")
        Dim drs = e.DataTable.Select("合并审理 ='" & str & "'")
        systemready = False
        If e.DataCol.name = "合并审理" AndAlso e.OldValue <> Nothing Then
            For Each dr As DataRow In e.DataTable.Select("合并审理 ='" & e.oldvalue & "' and _Identify <> '" & e.DataRow("_Identify") & "'")

                dr("合并审理") = Nothing
            Next
        End If
        Dim mc = System.Text.RegularExpressions.Regex.Matches(str, "(\([0-9]+\)[鲁0-9]+)|(行初[0-9\-]+)|(赔初[0-9\-]+)|(行终[0-9\-]+)|([0-9\-]+)")
        Dim qz As String = ""
        Dim lx As String = ""
        For i As Integer = 0 To mc.count-1
            Dim s As String = mc(i).value
           
            If i = 0 Then
                qz = s
            Else
                If s.StartsWith("行初") Then
                    lx = "行初"
                    s = s.replace("行初", "")
                ElseIf s.StartsWith("赔初") Then
                    lx = "行赔初"
                    s = s.replace("赔初", "")
                ElseIf s.StartsWith("行终") Then
                    lx = "行终"
                    s = s.replace("行终", "")
                End If
                Dim ii = 0
                Dim jj = 0
                If s.Indexof("-") >= 0 Then
                    ii = s.split("-")(0)
                    jj = s.split("-")(1)
                Else
                    ii = s
                    jj = s
                End If
                Dim count As Integer
                For k As Integer = ii To jj
                    count += 1
                    'msgbox(qz & lx & k & "号")
                    Dim dr1 As DataRow
                    dr1 = DataTables("数据表").Find("[案号] = '" & qz & lx & k & "号" & "'")
                    If dr1 IsNot Nothing Then
                        Dim ls As new List(of String)
                        Dim ls1 As new List(of String)
                        For Each cdr As DataRow In drs
                            For Each l As String In cdr.lines("原告出庭")
                                If ls.Contains(l) = False Then
                                    ls.Add(l)
                                End If
                            Next
                           
                            For Each l1 As String In cdr.lines("被告出庭")
                                If ls1.Contains(l1) = False Then
                                    ls1.Add(l1)
                                End If
                            Next
                        Next
                        dr1.lines("原告出庭") = ls
                        dr1.lines("被告出庭") = ls1
                        dr1("合并审理") = str
                        dr1("案件数量") = count
                        'msgbox（count）
                    End If
                Next
            End If
        Next
        systemready = True
End Select

我在[合并审理]列的单元格，减少案号，相应行的数据将删除。

但是相应行的[案件数量]却没有被删除。

我在上述代码后添加一段代码，结果也一样。

只能手动重置[合并审理]列，才能清除相应行的[案件数量]数据。代码重置也不行。

是什么原因？

添加的代码如下：

Select Case e.DataCol.Name
    Case "合并审理"
        If e.DataRow.isnull("合并审理") Then
            e.DataRow("案件数量") = Nothing
        End If

        'Dim drs As New List(of DataRow)
        'For Each dr As DataRow In drs
        'DataTables("数据表").DataCols("合并审理").RaiseDataColChanged(dr)   '重置列
        'Next
End Select

还是不行，并且手动重置[合并审理]，就把该列清除了。

请老师测试。

谢谢！
