\'首先生成统计表
Dim dt As DataTable
Dim b As New GroupTableBuilder("统计表1",DataTables("收文登记"))
b.Groups.AddDef("收到时间",DateGroupEnum.Year,"年")
b.Groups.AddDef("收到时间",DateGroupEnum.Month,"月")
b.Groups.AddDef("来文机关")
b.Totals.AddDef("编号",AggregateEnum.Count,"记录数") \'根据客户列来统计记录数,也就是订单数
dt = b.Build(False) \'参数设置为False,生成一个临时表,不在主界面显示
\'然后根据统计表生成目录树
Dim trv As WinForm.TreeView = e.Form.Controls("TreeView1")
trv.BuildTree(dt, "年|月|来文机关",,"年 desc")
trv.StopRedraw
For Each nd As WinForm.TreeNode In trv.AllNodes
Dim Year As Integer = nd.DataRow("年")
Dim Month As Integer = nd.DataRow("月")
Dim lwjg As String = nd.DataRow("来文机关")
Select Case nd.Level
Case 0
nd.Text = nd.text & "年(" & dt.Compute("Sum(记录数)","年 = " & Year) & "条)"
Case 1
nd.Text = nd.text & "月(" & dt.Compute("Sum(记录数)","年 = " & Year & " And 月 = " & Month) & "条)"
Case 2
nd.Text = nd.text & "(" & nd.DataRow("记录数") & "条)"
End Select
Next
trv.Nodes.Insert("显示所有记录","显示所有记录(" & dt.Compute("Sum(记录数)") & "条)",0)
trv.ResumeRedraw
高手看看哪里有问题？
