空的ListViewGroup没有在ListView中显示 [英] Empty ListViewGroup is not shown in ListView

问题描述

我找不到MSDN <一个在任何言论href="http://msdn.microsoft.com/en-us/library/system.windows.forms.listview.groups.aspx">ListView.Groups 是空的ListViewGroup房产将被隐藏。它是在设计上，还是我失去了一些东西？我的示例code以下，只显示组2项目ITEM1。

I could not find any remarks on MSDN ListView.Groups Property that empty ListViewGroup will be hidden. Is it by design, or I am missing something? My sample code below will show only "group 2" with item "item1".

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) _
      Handles MyBase.Load
    '
    Dim gr = New ListViewGroup("group 1")
    ListView1.Groups.Add(gr)
    '
    Dim gr2 = New ListViewGroup("group 2")
    ListView1.Groups.Add(gr2)
    '
    Dim lvi As New ListViewItem("item1")
    ListView1.Items.Add(lvi)
    '
    gr2.Items.Add(lvi)
End Sub

更新时间： 是否有任何方式来显示的ListViewGroup无需添加虚拟物品

Updated: Is there are any way to show ListViewGroup without adding dummy item

目前唯一的解决方法的想法我是用可折叠列表视图（Vista和最多）

For now the only workaround idea I have is to use collapsible listview (Vista and up)

推荐答案

无法通过微软设计的。照片 只看<一本讨论href="http://social.msdn.microsoft.com/forums/en-US/csharpgeneral/thread/39681a70-d992-4046-ad7e-21a2e33791b1"相对=nofollow> social.msdn.microsoft.com 。
不要被标题所迷惑。它谈论空组。

Is not possible by Microsoft design.
Look at this discussion on social.msdn.microsoft.com.
Don't be fooled by title. It talks about empty groups.
