Hello,
Please see attached code and video. I am using Syncfusion version 16.1. I think it is a bug.
When I use style Office2007 and set custom ForeColor for RadioButtonAdv in designer, ForeColor is reset back to black on setting Style property to Office2007. For CheckBoxAdv ForeColor remains unchanged on setting Style property. In version 15.1 neither changed, so I consider RadioButtonAdv behavior an issue.
Also, when I close and open project again, designer shows black ForeColor instead of the one I set manually. So to reproduce this you may need to manually set ForeColor on RadioButtonAdv as it was shown in the beginning of the video.
