In case a screen of a WPF application contains lots of primitive controls, its rendering becomes sluggish. What are the recommended ways to improve the responsiveness of a W
I've had the same perf issue with a heavily customized datagrid since one year, and My conclusion is:
there is basically nothing you can do on your side (without affecting you app, i.e.: having fewer controls or using only default styles)
The link mentioned by Jens is great but useless in your case.
The "Optimizing WPF Application Performance" link provided by NVM is almost equally useless in my experience: it just appeals to common sense and I am confident you won't learn anything extraordinary either reading. Except one thing maybe: I must say this link taught me to put as much as I can in my app's resource. Because WPF does not reinstanciate anything you put in resource, it simply reuses the same resource over and over. So put as much as you can in there (styles, brushes, templates, fonts...)
all in all, there is simply no way to make things go faster in WPF just by checking an option or turning off an other. You can just pray MS rework their rendering layer in the near future to optimize it and in the meantime, try to reduce your need for effects, customized controls and so on...
