使UI渲染更快 [英] Make UI rendering faster
问题描述
大家好，
在我们的应用程序中，我们使用3000个控件.这些控件是WPF控件和用户控件的组合(修改后的文本框为spinbutton).
In our application, we use 3000 controls. The controls are a combination of WPF controls and User controls(modified textbox for a spinbutton).
所有这些控件都是在运行时以编程方式添加的.加载GUI需要一分钟.
All these controls are added programmatically at Run time. It takes a minute to load the GUI.
有什么方法可以提高渲染速度?
Is there any way of improving the rendering speed?
谢谢

Viknesh Ramm，您好，
Hi Viknesh Ramm,
我们真的无法提供解决方案，因为我们对您的应用一无所知.
We can’t really give a solution as we know nothing about your app.
大量控件"与绘图性能成反比，通常，几乎使用任何框架，都无法优雅地处理大量控件.
您可以做很多事情来帮助您，但是总的来说，唯一真正的解决方案是使用更小的窗口和更少的控件.从可用性的角度来看，这通常会更好.
Large number of controls" is inversely proportional to drawing performance, in general, using nearly any framework, does not handle large numbers of controls gracefully.
There are many things you can do to help, but in general, the only real solution is to have smaller windows with fewer controls. From a usability standpoint, this is usually better anyways.
WPF不会为每个控件使用单独的窗口句柄-整个窗口只使用一个句柄，然后在该窗口中分别渲染每个控件.这使它可以通过数百个(甚至数千个)控件具有非常好的性能.如果您真的必须 这么多的控件，我建议您尝试使用更多的窗口，其中每个窗口具有较少的控件.不太好，一次只能在屏幕上显示很多信息.
WPF doesn't use a separate window handle per control - just one for the entire window, then renders each control separately in that window. This allows it to have very good performance with hundreds (or even thousands) of controls. If you really must have this many controls, I suggest you try to have more windows, where each window has a fewer number of controls. Not so good have so much info on the screen at one time.
WPF应用程序的性能与硬件成正比，因此，在没有图形加速设备的计算机上运行的WPF应用程序缓慢地成为公共秘密.除了改善硬件配置外，我们来看一些 改善WPF性能的软方法.这里只是几点，实际上您可以在互联网上找到很多东西.
WPF application performance is proportional to hardware , WPF application running on a machine that does not have a graphics acceleration device is slow to be a public secret. In addition to improving the hardware configuration, let's take a look at some soft ways to improve WPF performance. Here are just a few points, in fact you can find a lot on internet.
1. When your WPF program contains animations, you can use the BitmapScalingMode
property of the RenderOptions object to reduce resource consumption. You need to set the value of the BitMapScalingMode property to LowQuality, which will use the acceleration algorithm to process the image instead of the default high quality image weight
Sampling algorithm.
2. Having unnecessary elements in the visual tree also reduces the speed of the WPF program, When building a logical tree or visual tree, follow the Top-Down principle.
3.更多地使用静态资源.请参阅:
XAML资源
4.要显示大数据时，请使用UI虚拟化控件.请参阅:优化性能:控件
5.因为可滚动的DataGrid或ListBox将在滚动时强制进行连续更新，这是默认行为，并且它们会降低整个应用程序的性能.在这种情况下，我们可以使用
控制以增强用户体验.您需要做的就是将IsDeferredScrollingEnabled附加属性设置为True.
3. More use of static resources. See :
XAML Resources
4. When you want to display large data, use UI virtualization controls. See : Optimizing Performance: Controls
5. Because the scrollable DataGrid or ListBox will force continuous updates when scrolling, which is the default behavior, and they tend to degrade the performance of the entire application. In this case, we can use the Deferred Scrolling property of the
control to enhance user experience. All you need to do is set the IsDeferredScrollingEnabled additional property to True.
6.尝试使用WPF 表演套件分析WPF应用程序的运行时行为并确定可以应用的性能优化.
6. Try to use WPF
Performance Suite to analyze the run-time behavior of your WPF applications and determine performance optimizations that you can apply.
