由于PropertyGrid，导致速度慢的都市地铁对话框打开的可能原因

Question

I'm investigating why opening a dialog in a mahapps application is much slower than the other dialogs in the same application, but I'm having trouble making progress, or even knowing where to look.

It's a dialog that contains a collection of options, when I run a profiler on the code all it gives me is that the majority of the work is happening inside the PresentationFramework dll, and a lot of the time is taken up by a PropertyGrid.

Sorry that this is a bit vague, I'm mostly just looking for direction on what sort of thing I should investigate when trying to debug something like this. Any help is greatly appreciated.

Answer 1

Tools -> Options -> Debugging -> Output Window. If you change all debugging levels to verbose, you'll see in Output window a detailed report on each issue or binding error you have when the dialog starts.

I also recommend VSColorOutput extension - it will add colors to messages in output and will help you spotting errors.
