Hi Damien,
Thank you for writing.
I can suggest using the standard StarShapes which are supported by our
framework. Additional information is available here:
https://docs.telerik.com/devtools/winforms/telerik-presentation-framework/shapes/star-shape. As I understand you would like each of the radio buttons to have an individual fill color when it gets selected. For such a scenario you can consider applying the settings for each of the buttons at run-time. For example like this:
If you would prefer to use images you can achieve it this way:
Please also note that with the approach using images you will also need to manually handle the image for the
Checked toggle state. A suitable place to do this is the handler of the
ToggleStateChanged event.
I hope this helps. Let me know if you need further assistance.
Regards,
Hristo
