ListView无法忍受 [英] ListView Unbearable
问题描述
还有其他人注意到ListView的难以忍受的闪烁吗？
我有一个包含列表视图的项目，其中包含以下内容：
- 查看：详细信息
- 列：5
以下代码导致列表视图闪烁：
private void TestListView（）
{
const int Num = 20;
const string Text =" Test";
listView.BeginUpdate（）;
listView.Items.Clear（）;
ListViewItem [] items = new ListViewItem [Num];
for（int i = 0; i< items.Length; ++ i）{
ListViewItem item = new ListViewItem（Text）;
item.SubItems.Add（Text）;
items [i] = item;
}
listView.Items.AddRange（items）;
listView.EndUpdate（）;
}
它貌似.NET让我再次失望;由于这个原因，我可能不得不为项目使用另一个
框架。
Has anyone else noticed ListView''s unbearable flickering?
I have a project containing a list-view with the following:
- View: Details
- Columns: 5
The following code causes the list-view to flicker:
private void TestListView()
{
const int Num = 20;
const string Text = "Test";
listView.BeginUpdate();
listView.Items.Clear();
ListViewItem[] items = new ListViewItem[Num];
for (int i = 0; i < items.Length; ++i) {
ListViewItem item = new ListViewItem(Text);
item.SubItems.Add(Text);
items[i] = item;
}
listView.Items.AddRange(items);
listView.EndUpdate();
}
It looks like .NET let me down again; I might have to use another
framework for the project due to this.

我是.NET的新手，所以我没玩过还有，但是当我遇到问题
在其他环境中闪烁时，我通常可以找到一些方法来转换
更新它以消除闪烁。在Access中，
将是< form> .Painting = False ...做东西......< form> .Paining = True。
I''m new to .NET, so I haven''t played with that yet, but when I have problems
with flickering in other environments, I can usually find some way to turn
painting off while updating it to get rid of the flickering. In Access, that
would be <form>.Painting = False ... do stuff ... <form>.Paining = True.

是的，这就是ListView.BeingUpdate（）和ListView.EndUpdate（）在这里做的
。 .NET可能非常VCL-ish。
Yeah, that''s what ListView.BeingUpdate() and ListView.EndUpdate() do
here. .NET can be very VCL-ish.
首先我添加了microsoft.public.dotnet.framework.windowsforms.con trols
这是因为它不是C＃问题。
你究竟看到了什么以及这款新的
PC的具体规格是什么？我已经在下面运行你的代码并且闪电般快速（Athlon 2600 /
Radeon 9700 Pro），20个，50个甚至1000个项目。

First I''ve added microsoft.public.dotnet.framework.windowsforms.con trols
this to thread because it''s not a C# issue.
What exactly are you seeing and what exactly are the specs of your this new
PC? I have run your code below and it was lightning fast (Athlon 2600 /
Radeon 9700 Pro) for 20, 50 even 1000 items.
