问题描述
我的WPF应用程序是在高分辨率下有点慢，当涉及到组合框。我是pretty的确定及其对组合框的BitmapEffects，在ItemsPanel特别是阴影的效应。
My WPF Application is kinda slow in high resolutions when it comes to ComboBoxes. I am pretty sure its the BitmapEffects on the ComboBoxes, especially the DropShadow-Effect on the ItemsPanel.
我如何可以将其禁用或彻底删除所有位图效果的组合框和它的孩子？
How can I disable it or completely remove all Bitmap Effects on the ComboBoxes and its children?
推荐答案
您可以尝试更改的。但是我建议先来分析，前松了大量的时间来优化你的东西只怀疑是缓慢的。
You can try to change the ControlTemplate of the ComboBox. However I would propose to profile first, before loose a lot of time for optimizing things you only suspect to be slow.
微软分析工具是非常强大的个人资料WPF的图形用户界面。
The microsoft profiling tools are very powerfull to profile WPF-GUIs.
我还没有研究，但我不认为MS使用 BitmapEffects 在 CONTROLTEMPLATES 。不过，我已经看到的情况下使用 DropShadowEffect （这不是 BitmapEffect ）影响业绩非常不利：在其内的更新已标记在整个屏幕为无效的内容。随着性能分析工具中的穿孔，你会发现并解决这些问题非常快。
I have not looked into but I don't think that MS uses BitmapEffects in its ControlTemplates. However I already have seen a case where using the DropShadowEffect (this is not a BitmapEffect) has influenced performance very negatively: Updates within it have marked the content of the whole screen as invalid. With Perforator of the performance profiling tools, you will find and fix such problems very fast.
