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

• "small"
• "medium"
• "large"

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

Example - sets a size

<input id="textbox" />
<script>
$("#textbox").kendoTextBox({
    size: "large",
    rounded: "large"
});
</script>
