主题：[求助]下拉窗口节点选择按钮

1、你按钮显示的路径要动态获取？根据什么获取，逻辑是什么？

2、参考代码

Dim trv As WinForm.TreeView = e.Form.Controls("TreeView1")
Dim path As String = "中国/广东/广州"
Dim ary() As String = path.split("/")
For i As Integer = 0 To ary.length-1
    For Each nd As WinForm.TreeNode In trv.AllNodes
        If nd.Level = i Then
            If nd.name.contains(ary(i)) Then
                nd.Checked = True
                trv.SelectedNode = nd
            End If
        End If
    Next
Next

AfterCheckNode事件

'''...
dim s1 as string = ""
dim s2 as string = ""
for each nd as WinForm.TreeNode in e.Sender.AllNodes
    if nd.Checked then
        s1 &= nd.FullName & ","
        s2 &= nd.Name & ","
    end if
next
e.Form.controls("button1").text = "全路径：" & s1.trim(",")
e.Form.controls("button2").text = "末路径：" & s2.trim(",")
