Winforms：当有垂直滚动条时，如何以编程方式显示C＃listview中的最后一项？

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#listview中的最后一项?我研究了与listviews相关的每个方法,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/可能。您需要告诉该项目以确保它可见。

var items = listView.Items;
var last = items[items.Count-1];
last.EnsureVisible();

#2

this.listView1.Items[this.listView1.Items.Count - 1].EnsureVisible();

#3

ListViewItem.EnsureVisible()

#4

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.

我认为这样做会集中在最后一项......如果是必要的话,向下滚动。但我没有尝试过自己。

EDIT: This will do the trick:

编辑:这将做的伎俩:

Me.ListView1.Items(Me.ListView1.Items.Count - 1).EnsureVisible()

WPF or WinForms?

WPF还是WinForms?

In WPF, you get the ListViewItem and call BringIntoView on it.

在WPF中,您获取ListViewItem并在其上调用BringIntoView。

This is a link to using a windows function to hide the horizontal and force vertical to be shown at all times:

这是一个使用Windows功能隐藏水平和强制垂直的链接,以便随时显示:

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。不知道为什么这样有效,但它确实有效。

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 ClientArea width before calling BeginInvoke.

此外,如果您不想显示水平滚动条,则需要在调用BeginInvoke之前调整ListView列的大小以适合ListView的ClientArea宽度。
