New Post: Dynamically change theme of PropertyGrid

Hello, I'm newbie who experements with themes of app for job-interview:)

I dynamically change themes for the Propertygrid. I modified default theme in PropertyGrid/Generics.xaml for it by changing color and placed it to run-time theme file. But property name and grid of items still have default color. How to do it?

I tried to change colors for another controls(combobox, textbox), but it gave no success for vision of PropertyGrid. I see changes of colors only for checkbox.
