fillModeString(default: undefined)
Controls how the color is applied to the buttons in the Group. When undefined (the default), the theme controls the default fill mode. Valid values are: "solid", "outline", "flat", "link".
The
"none"value is deprecated. Use custom CSS instead.
Example
<div id="buttonGroup"></div>
<script>
$("#buttonGroup").kendoButtonGroup({
fillMode: "outline",
items: [
{ text: "<b>foo</b>", encoded: false },
{ text: "<b>bar</b>", encoded: true }
]
});
</script>
