Options

The Size() method controls how big or small the rendered radio input looks.

The example below demonstrates how to adjust the Size of the component:

@(Html.Kendo().RadioButton()
    .Name("radioBtn")
    .Checked(true)
    .Size(ComponentSize.Small)
)

<kendo-radiobutton name="radioBtn" checked="true" size="small"></kendo-radiobutton>

The following values are available for the Size option:

The default size value is Medium and it is added as a class k-radio-md to the input element.

<!-- default rendering -->
<input type="radio" class="k-radio k-radio-md" id="radioButtonName"/>
