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

• "small"
• "medium"
• "large"
• "full"

The "none" value is deprecated. Use custom CSS instead.

Example - sets the rounded value

<input id="combobox"/>
<script>
  $("#combobox").kendoComboBox({
    dataSource: [
      { id: 1, name: "Apples" },
      { id: 2, name: "Oranges" }
    ],
    dataTextField: "name",
    dataValueField: "id",
    rounded: "large"
  });
</script>
