其实我早就特么想驳回了

这是工控上位机里显示对电池管理系统（BMS）的采样数据，一个BMS接了可能有400个单体电芯，每个电芯有单体电压、单体温度，这特么加起来就800个信号了。

其实只需要显示最大最小值就可以了，关键是设备有没有处于危险中。但客户说他们会看，不过我信你个鬼。

@血狼一族: 800个能看过来吗....。我建议是这样：用户其实关心的是是否异常，可以让用户自己设置一些阈值，程序自动监控，如果某些数据超过阈值，就报警，用户可以快速定位到问题数据。。如果非要全看，加上分页和查询过滤。

谁都知道看不过来啊！但是客户就是说我要看！

现在正在找别的门路跟客户沟通去掉这么BT的要求。

我的担心是，万一WPF（或者WinForm，主要客户才不关注你是WPF还是WinForm，甚至可能是 Delphi ）确实能够支持这种BT功能，不然客户拿别的产品往你面前一摆：瞧，人家咋搞得定，你咋就不行！

@血狼一族: 我还有一个疑问，为什么用listview，而不用datagrid？听你的描述datagrid更合适。另外，你那里有可以运行的demo吗，发上来，我想在你demo的基础上试试看

@会长: 参考你的代码，用 DataGrid 取代原来的 ListView，再加上虚拟化，已经好很多了。但在数据量大时还是有点卡。ListView 加虚拟化似乎没什么变化。

前面也很多都和题主一样，认为这个需求很BT。其实用户的想法很没那么复杂，单纯的用Excle表格习惯了而已。

对用户来说，分页、拉到底才加载(下拉分页)什么的用起来麻烦。

而且工业软件和平台互联网应用不太一样，很容易出现需要大量展示数据的场景，不能完全说需求变态。

我们也遇到过这样的需求，只是我们是Web端，表格列和行极限大约在30/1W多的样子，而且我们的数据是还需要实时更新，更新延迟要控制在1分钟内。先前做分页，渐进加载被客户投诉好几回，开会讨论好多回，最后老板拍板，把那些都删除了，后来就是大帐户一登录就卡得一塌糊涂，客户反而不投诉了，开始反映系统卡但闹得也没这么凶了。然后，就是漫长的解决问题之路，讨论怎么拆分业务不显示这么多数据，表格虚拟化等，反正现在还行，双方都可以接受。
如里业务确实无法拆分，要实现这个，只能从虚拟化入手，毕竟用户可视区就那么大。但是基本上都需要定制，用控制内置的效果可能不太理想。我们先前的项目改造的重点就是去掉vue表格原生数据变动监听（自定义虚拟化渲染）。

难点往往在于识别那些行/列是当前显示在用户视区范围内的，然后用户拖动滚动条（或键盘移动）时实时渲染可视区数据。全部数据可以放在内存中，也可以放到SQLite中。

对WPF不太了解，但使用内置控件时可以考虑取消双向绑定（不需要编辑数据时）和数据变化监听（不用实时刷新时）。
这个业务还真不好拆分
简单来说，是个工控方面的数据显示控件。数据列分为两大类，一类是固定的必须有的数据，不多，也就20几个，象序号、采样时间、电流、电压、温度、功率之类的。另一类是动态的，比如实际运行时，接了10个电池，每个电池20个电芯，每个电芯有电压、温度两个量，这样就有10*20*2=400个量，再加上统计出来的单体电芯最高电压、最低电压、最高温度、最低温度，就是404个。
最好的方式就是显示固定数据之后，再加上最高/最低的电压和温度，另外400个就不显示了。但那400个信号，其实都没差别，不好分哪个重要哪个次要。

5w行不过分，应该现在的机器5w个粒子60FPS都没问题。
桌面端的意义正在于此，不然用什么桌面端，用网页做就行了。
10多年前别个c#绘制的实时曲线都是几十万个点。
实时的话无非就是内存绘制而已，如果非即时无非就是loading或者自行绘制进行优化。
这里说一个类似简单办法，直接绘制成图片（内存），然后贴到控件上去。当然也可以通过处理滚动等等方式处理。第一种方法最简单，代码最少。
                        
@血狼一族: 光显示出来应该问题不大，关键是他这个也应该需要实时更新的吧！难度还是不小哦。

另外，参考一下Excel/WPS表格，800列表、10W数据也够呛。
听说，微软内部office也试着用.NET来重写，最后性能很不好放弃了，现在都只是套壳。

如果是这样的话，Excel都卡的数据量，c#/WPF再怎么优化恐怕也是枉然哦。
