I want to change the shape of the radio button, can I change the border size?
I'm trying to change the shape of a radio button's appearance using a control template. But I want to change the border thickness of the frame, but there is no way.
The default thickness is too thick. I've looked for many other examples, but there's no information about the thickness, so I'm asking.
