ClassRadCallout
Represents a customizable callout control that provides various shapes and styles for displaying content in a user-friendly manner. The RadCallout class allows users to configure properties such as callout type, arrow type, geometry, text alignment, wrapping, trimming, and corner radius, enabling the creation of visually distinct callouts for user interfaces. It inherits from ContentControl and supports properties for defining geometry and visual appearance, allowing for flexible layouts and detailed customization. Ideal for enhancing user experience with informative overlays that can be styled to match application design.
