Sets a value controlling the size of the badge. When undefined (the default), the theme controls the size. Can also be set to the following string values:

• "small"
• "medium"
• "large"

Example

<button id="button">Button</button>
<script>
  $("#button").kendoButton({
    badge: {
      text: "10",
      size: "large"
    }
  });
</script>
