The [FormattingStyle]( https://docs.textcontrol.com/textcontrol/windows-forms/ref.txtextcontrol.formattingstyle.class.htm "FormattingStyle class") class is the base class for the two different supported style classes: [InlineStyle]( https://docs.textcontrol.com/textcontrol/windows-forms/ref.txtextcontrol.inlinestyle.class.htm "Inline style class") and [ParagraphStyle]( https://docs.textcontrol.com/textcontrol/windows-forms/ref.txtextcontrol.paragraphstyle.class.htm "Paragraph style class"). These classes can be used to change the styles. TX Text Control ActiveX offers a [Style](https://www.textcontrol.com/ "Style object") object that represents a formatting style. The [Styles](https://www.textcontrol.com/ "Styles collection") collection represents all formatting styles a TX Text Control document contains. A common task is to access an existing style and to change some attributes. Consider a style with the name *Headline*. To modify this style, the *Item* method must be called with the name of the style. After that, the properties of the *Style* object can be modified. Then, the modifications and the *Apply* method must be used to confirm the changes. The following sample code shows this in detail. ``` Set style = TXTextControl1.Styles.Item("Headline") style.FontName = "Arial" style.FontSize = 400 style.Apply ``` --- ## About Bjoern Meyer As CEO, Bjoern is the visionary behind our strategic direction and business development, bridging the gap between our customers and engineering teams.
