Returns or sets the underline font style. At design time the property determines the style of the complete text. At runtime the property gets or sets the style of the selected text if the [FormatSelection](https://docs.textcontrol.com/tx-text-control-activex/reference/txtextcontrol/formatselection-property/llms-full.txt) property has been set to True. If the [FormatSelection](https://docs.textcontrol.com/tx-text-control-activex/reference/txtextcontrol/formatselection-property/llms-full.txt) property has been set to False the style setting is made for the complete text.

### Syntax
