Winforms: How can I programmatically display the last item in a C# listview when there are vertical scrollbars?
提问by Auburnate
How can I programmatically display the last item in a C# listview when there are vertical scrollbars? I've studied every method associated with listviews and can't find anything.
当有垂直滚动条时，如何以编程方式显示 C# 列表视图中的最后一项？我研究了与列表视图相关的所有方法，但找不到任何东西。

It's not actually easy/possible to scroll the list view. You need to tell the item to make sure it's visible.
滚动列表视图实际上并不容易/不可能。您需要告诉项目以确保它是可见的。
var items = listView.Items;
var last = items[items.Count-1];
last.EnsureVisible();

WPF or WinForms?
WPF 还是 WinForms？
In WPF, you get the ListViewItemand call BringIntoViewon it.
在 WPF 中，您可以获得ListViewItem并调用BringIntoView它。

WINFORMS：
Did you try setting the Selected value to TRUE in the last item in the Items collection of the ListView?
您是否尝试在 ListView 的 Items 集合的最后一项中将 Selected 值设置为 TRUE？
I think that doing this will focus on the last item... scrolling down if it is necesary. But I did't tryed myself.
我认为这样做将集中在最后一项......如果有必要，向下滚动。不过我自己没试过。
EDIT: This will do the trick:
编辑： 这可以解决问题：
Me.ListView1.Items(Me.ListView1.Items.Count - 1).EnsureVisible()

This is a link to using a windows function to hide the horizontal and force vertical to be shown at all times:
这是使用 windows 函数隐藏水平并始终强制显示垂直的链接：

The following hack will both select and show the last ListView item.
Not sure why this works but it works.
以下 hack 将选择并显示最后一个 ListView 项目。
不知道为什么这有效，但它有效。
listview.SelectedIndices.Clear();
listview.FocusedItem = listview.Items[listview.Items.Count - 1];
listview.FocusedItem.Selected = true;
listview.BeginInvoke((MethodInvoker)delegate {
listview.FocusedItem.EnsureVisible();
});
Also, if you don't want a horizontal scroll bar to show, you need to resize ListView columns to fit the ListView's ClientAreawidth before calling BeginInvoke.
此外，如果您不想显示水平滚动条，则需要ClientArea在调用BeginInvoke.
