Sets a value controlling how the color is applied to the badge. When undefined (the default), the theme controls the fill mode. Can also be set to the following string values:

• "solid"
• "outline"

Example

<button id="button">Button</button>
<script>
  $("#button").kendoButton({
    badge: {
      text: "3",
      fillMode: "outline",
      themeColor: "primary"
    }
  });
</script>
