Gets or sets the description of the control used by accessibility client applications.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
An object's 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 property is needed if the description is not obvious, or if it is redundant based on the object's AccessibleName, AccessibleRole, State, and 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 AccessibleName, and AccessibleRole (and perhaps Help) properties for the cactus button would describe its purpose, but the property would convey information that is less tangible, such as "A button that shows a picture of a cactus."
For more information about properties of accessible objects, see the "Content of Descriptive Properties" topic in the MSDN library at http://msdn.microsoft.com/library.
The following code example creates an instance of a CheckBox derived class, MyCheckBox, assigns it an Image to its Image property and sets the AccessibleName and properties, because the Text property is a null reference (Nothing in Visual Basic). This example requires that you have a Form named MyForm.
