This section contains information on features common to multiple DevExpress VCL controls.
Accessibility SupportUI Automation-based accessibility features (such as Microsoft Narrator) rely on the Microsoft UI Automation (UIA) framework to obtain information about UI elements in an application.AI-powered Extensions
AI-powered Extensions leverage advanced natural language processing (NLP) technologies to offer automated, intelligent text editing functionality directly within your VCL applications.
Note
All DevExpress AI-powered Extensions follow the bring your own key principle. DevExpress does not offer a REST API and does not ship any built-in LLMs/SLMs. You need an active Azure, OpenAI, or other AI service subscription to obtain the REST API endpoint, key, and model deployment name.
BBCode-Inspired Text Formatting MarkupCaptions in multiple DevExpress controls can use Bulletin Board Code (BBCode) markup tags. These tags can define hyperlinks and apply formatting attributes – bold, italic, superscript, underline, etc.Message Dialog BoxesA message box is a modal dialog designed to display important information and optionally allow a user to make a choice or confirm an operation. All DevExpress products use the TdxMessageDialogForm class to display message dialog boxes that support skins and BBCode-inspired markup tags. See Also
