Winforms SplitContainer中的Top ListView赢得'；添加垂直滚动条

我有一个Winforms应用程序，在一个SplitContainer中有两个ListView

当我拖动拆分器隐藏部分Panel2 ListView项目时，它会自动添加一个垂直滚动条。

当我拖动拆分器以隐藏部分Panel1 ListView项目时，它不会添加垂直滚动条。

更改具有相同行为的面板中的哪个ListView。这就好像SplitContainer或它的面板控制着垂直滚动条是否被添加到Panel1中的ListView中。如何使顶部面板中的列表视图1也自动添加垂直滚动条

要进行复制，请使用一个表单创建一个简单的Winforms应用程序。下面是我的表单代码，后面是设计器表单代码

Public Class Form1
    Private Sub Form1_Shown(sender As Object, e As EventArgs) Handles Me.Shown
        Timer1.Enabled = True
    End Sub

    Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
        Try
            Timer1.Enabled = False

            TechDateList.BeginUpdate()
            TechDateList.Items.Clear()
            StopsList.BeginUpdate()
            StopsList.Items.Clear()

            For i As Integer = 1 To 5
                Dim techItem = New ListViewItem
                techItem.UseItemStyleForSubItems = False
                techItem.SubItems(0).Text = Date.Now.ToString("MMM dd, yyyy")
                techItem.SubItems.Add(String.Format("Tech {0}", i))
                TechDateList.Items.Add(techItem)
            Next

            For i As Integer = 1 To 5
                Dim stopItem = New ListViewItem
                stopItem.UseItemStyleForSubItems = False
                stopItem.SubItems(0).Text = Choose(i, "AAA", "BBB", "CCC", "DDD", "EEE")
                stopItem.SubItems.Add(String.Format("Stop {0}", i))
                StopsList.Items.Add(stopItem)
            Next
        Catch ex As Exception
            MsgBox(ex.ToString(), MsgBoxStyle.Critical + MsgBoxStyle.OkOnly, "Timer1_Tick Error 1")
        Finally
            TechDateList.EndUpdate()
            StopsList.EndUpdate()
        End Try

        Try
            ListSplitter.Panel1Collapsed = False
            ListSplitter.SplitterDistance = 125
            ListSplitter.SplitterWidth = 6
            TechDateList.Items.Item(0).Selected = True
        Catch ex As Exception
            MsgBox(ex.ToString(), MsgBoxStyle.Critical + MsgBoxStyle.OkOnly, "Timer1_Tick Error 2")
        End Try
    End Sub
End Class
