基本逻辑问题，选了父子并不需要同时选。

Afterchecknode的事件代码改为：

Dim trv As WinForm.TreeView = e.sender
If e.node.ParentNode IsNot Nothing Then
    e.node.ParentNode.Checked = False
End If
For Each nd As WinForm.TreeNode In e.node.Nodes
    nd.Checked = False
Next
Dim s As String
For Each nd As WinForm.TreeNode In trv.Nodes(0).Nodes
    Dim v As String = ""
    If nd.Checked Then
        v = nd.Text & "/all"
    Else
        For Each cd As WinForm.TreeNode In nd.Nodes
            If cd.Checked Then
                If v = "" Then
                    v = v & nd.Text & "/"
                End If
                v = v & cd.Text & ","
            End If
        Next
    End If
    If v > "" Then
        If s > "" Then
            s = s & vbcrlf
        End If
        s = s & v.Trim(",")
    End If
Next
MessageBox.show(s)

 你选择了11日，默认的意思，就是选择了全部的意思啊。

 你可以不勾选11日。
