Controls how the color is applied to the button. Valid values are: "solid", "outline", "flat", and "link". When undefined (the default), the theme controls the default fill mode.

The "none" value is deprecated. Use custom CSS to achieve an unstyled appearance.

Example

<button id="button" type="button">Cancel</button>
<script>
    $("#button").kendoButton({
        fillMode: "outline"
    });
</script>
