1、AfterLoad事件中
Dim dt As DataTable
Dim jb As New SQLJoinTableBuilder("查询表1","招标信息")
jb.AddTable("招标信息","项目编号","标录信息","项目编号")
jb.AddCols("{标录信息}.项目编号","{招标信息}.项目名称","咨询类型","归属部门","投标地区")
dt = jb.Build(True) '参数设置为True,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,"咨询类型|归属部门|投标地区")
trv.Nodes.Insert("显示所有行",0)
2、
Dim nms As String() = {"咨询类型","归属部门","投标地区"} '指定生成目录树的各列
Dim qts As String() = {"'","'","'"} '指定将各列的值括起来的符号,这里都是字符型,所以都是单引号
Dim trv As WinForm.TreeView = e.Sender
Dim flt As String
Dim nd As WinForm.TreeNode
For Each nd In e.node.allNodes '清除子节点的选中标记
nd.Checked = False
Next
nd = e.Node.ParentNode
Do While nd IsNot Nothing '清除父节点的选中标记
nd.Checked = False
nd = nd.ParentNode
Loop
For Each nd In trv.AllNodes
If nd.Checked Then
Dim rts() As String = nd.FullPath.Split("\")
Dim val As String = ""
For i As Integer = 0 To rts.length - 1
If val > "" Then
val = val & " And "
End If
val = val & nms(i) & " = " & qts(i) & rts(i) & qts(i)
Next
If flt > "" Then
flt = flt & " Or (" & val & ")"
Else
flt = val
End If
End If
Next
Tables("标录信息_table1").Filter = flt
我的需求是：通过生成临时表"查询表1"，并生成目录树，根据“项目编号”列进行筛选？如何调整？
