Certain Windows Forms controls can display an HTML formatted text, either according to the HTML tags or as a plain text. XAF provides an easy way to enable HTML formatting in List Editors and View Items that use such controls. To enable HTML formatting, set the IModelOptionsEnableHtmlFormatting.EnableHtmlFormatting property of the Application Model's Options node to true. This affects all the List Editors and View Items that implement the IHtmlFormattingSupport interface.
The IHtmlFormattingSupport interface exposes a single IHtmlFormattingSupport.SetHtmlFormattingEnabled method that enables or disables HTML formatting.
When implementing a custom List Editor or a View Item, support this interface if the control you are using can format the display text according to Hyper Text Markup Language.
