I am using a few RadioButton controls and I simply copied and pasted the code from your documentation into my code. There is no functionality to control the icon that appears in the center of the RadioButton when isChecked = true. At least not that I've seen. In the documentation it appears to be an "x" in the center of the checked RadioButton. Whenever I check any of my RadioButtons a white circle appears in the center of my RadioButton. Any help would be appreciated.
