ContextMenu - Popup

[Mark Gambo]

I am using the following code to display a popup menu for a particular node of a treeview:

Private Sub TreeView1_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles TreeView1.MouseUp
        Dim mnuContextMenu As New ContextMenu()
        If e.Button = Windows.Forms.MouseButtons.Right Then
            Dim mnuItemNew() As MenuItem = New MenuItem() _
                        {New MenuItem("Item 1"), _
                        New MenuItem("Item 2"), _
                        New MenuItem("Item 3")}
 
            Dim TVWMenu As New ContextMenu(mnuItemNew)
            TVWMenu.Show(TreeView1, New Point(e.X, e.Y))
        End If
    End Sub

My question is how do I have a separator line appear Item 2 and Item 3? How can I tell which item was clicked? I have tried the following code but it didn't work:

Private Sub ContextMenuStrip1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ContextMenuStrip1.Click
        MsgBox(ContextMenuStrip1.Text)
    End Sub

Thanks
