roundedString(default: undefined)
Controls what border radius is applied to a button. When undefined (the default), the theme controls the default border radius. Valid values are: "small", "medium", "large", "full".
The
"none"value is deprecated. Use custom CSS instead.
Example
<button id="splitbutton" type="button">Cancel</button>
<script>
$("#splitbutton").kendoSplitButton({
items:[
{ text: "item 1" },
{ text: "item 2" }
],
rounded: "full"
});
</script>
