Short answer is unfortunately it's not possible using two color in images. IconView fills all pixels with color of an image. That is used logic to change colors. I think a property can be added as IsFillColorActive
or something like this.
But you can try add this:
rb.ApplyIsCheckedAction = (isChecked) =>
{
//you can switch between 2 images when every check changed.
rb.CircleImage = isChecked ? "my_custom_image.png" : "circle_open.png";
rb.ApplyIsChecked(isChecked);
};
Each element uses default Action which named without Action suffix. In this situation, for example: RadioButton calls ApplyIsCheckedAction and this action calls ApplyIsChanged method as default. You can change what will happen when control check changed.
The goal is to have a white background on the circle portion of the radio button and since I could not find a property that would show the background as white and still have the border I attempted to create custom images. PNG circle with solid border and white fill with no background outside the circle.
Create the control from codebehind like so:
The control then shows solid color of your defaults or whatever I set color / circle color to in the circle area, no sign of the images I want to use. I have tried various color combinations and transparency trying to get some better result but have yet to see the images.
Whereas I expected to just see the image I set as the checked or unchecked background??
