An object's Control.AccessibleDescription property provides a textual description about an object's visual appearance. The description is primarily used to provide greater context for low-vision or blind users, but can also be used for context searching or other applications.

The Control.AccessibleDescription property is needed if the description is not obvious, or if it is redundant based on the object's Control.AccessibleName, Control.AccessibleRole, AccessibleObject.State, and AccessibleObject.Value properties. For example, a button with "OK" would not need additional information, but a button that shows a picture of a cactus would. The Control.AccessibleName, and Control.AccessibleRole (and perhaps AccessibleObject.Help) properties for the cactus button would describe its purpose, but the Control.AccessibleDescription property would convey information that is less tangible, such as "A button that shows a picture of a cactus."
