Label and Size in JavaScript RadioButton control

28 Jul 2021 / 2 minutes to read

This section explains the different sizes and labels.

Label

RadioButton caption can be defined by using the label property. This reduces the manual addition of label for RadioButton. You can customize the label position before or after the RadioButton through the labelPosition property.
