专家坐堂-多个treeview里的内容，能否自定义汇总到一个treeview里面？Foxtable(狐表) - 新一代数据库软件，完美融合Access、Foxpro、Excel、vb.net之优势，人人都能掌握的快速软件开发工具!

\'首先生成统计表

Dim dt As DataTable

Dim b As New GroupTableBuilder("统计表1",DataTables("销售项目库"))

b.Groups.AddDef("发货状态")

b.Groups.AddDef("回款_回款状态")

b.Groups.AddDef("客户名称")

b.Totals.AddDef("销售项目编码",AggregateEnum.Count,"人数") \'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("销售管理TreeView1")

trv.BuildTree(dt, "发货状态|回款_回款状态|客户名称")

trv.StopRedraw

For Each nd As WinForm.TreeNode In trv.AllNodes

Dim cj As String = nd.DataRow("发货状态")

Dim ks As String = nd.DataRow("回款_回款状态")

Dim kh As String = nd.DataRow("客户名称")

Select Case nd.Level

Case 0

nd.Text = nd.text & "(" & dt.Compute("Sum(人数)","发货状态 = \'" & cj & "\'") & "条)"

Case 1

nd.Text = nd.text & "(" & dt.Compute("Sum(人数)","发货状态 = \'" & cj & "\' And 回款_回款状态 = \'" & ks & "\'") & "条)"

Case 2

nd.Text = nd.text & "(" & dt.Compute("Sum(人数)","发货状态 = \'" & cj & "\' And 回款_回款状态 = \'" & ks & "\' And 客户名称 = \'" & kh & "\'") & "条)"

End Select

trv.Nodes.Insert("显示所有待发货项目","显示所有待发货项目(" & dt.Compute("Sum(人数)") & "条)",0)

trv.ResumeRedraw

\'--------------------------------------------------

\'以上生成待发货项目统计树

Dim cj As String =""

Dim dr As DataRow = e.Node.DataRow \'获取生成此节点的行

If e.Node.name <> "显示所有待发货项目" Then \'要用Name属性,不能用Text属性

Select Case e.Node.Level

Case 0

cj = "[发货状态] = \'" & dr("发货状态") & "\'"

Case 1

cj = "[发货状态] = \'" & dr("发货状态") & "\' And [回款_回款状态] = \'" & dr("回款_回款状态") & "\'"

Case 2

cj = "[发货状态] = \'" & dr("发货状态") & "\' And [回款_回款状态] = \'" & dr("回款_回款状态") & "\' And [客户名称] = \'" & dr("客户名称") & "\'"

End Select

End If

Tables("销售项目库").Filter = cj
