主题：目录树生成的列是通过变更传递进来的，如何写单击事件

vars("TreeViewStr")="窗口名称|窗口标题|数据表名"

Dim tb As Table = e.Form.Controls("Table1").Table
Dim trv As WinForm.TreeView = e.Form.Controls("TreeView1")
trv.BuildTree(tb.DataTable.name,vars("TreeViewStr"))
trv.Nodes.Insert("显示全部",0)

目录树是通过 vars("TreeViewStr") 变量传递进来生成的

单击筛选事件 如何写 代码

下面这样写怎么不行 

Dim tb As Table = e.Form.Controls("Table1").Table
Dim Filter As String = ""
Dim Valuea() As String
Dim Value() As String
Value = e.Node.FullPath.Split("\")
Valuea = vars("TreeViewStr").Split("|")
If e.Node.Text <> "显示所有行" Then
    Select Case e.Node.Level
        Case 0
            Filter = "Valuea(0) = '" & Value(0) & "'"
        Case 1
            Filter = "Valuea(0) = '" & Value(0) & "' And Valuea(1)  = '" & Value(1) & "'"
        Case 2
            Filter = "Valuea(0) = '" & Value(0) & "' And Valuea(1)  = '" & Value(1) & "' And Valuea(2)  = '" & Value(2) & "'"
    End Select
End If
tb.Filter = Filter

Filter = "窗口名称 = '" & Value(0) & "'"  这样写 运行正常

Filter = "Valuea(0) = '" & Value(0) & "'" ，这样写 就运行不正常。 这时 msgbox(Valuea(0)) 显示为 窗口名称

即 如何在列名处，不写列名 而用变量代替

搞定了
