With respect to previous versions of the component, internal design has been changed in order to support a more object-oriented approach during the development of applications: this has caused some of the control's properties and methods to become obsolete. These obsolete properties and methods should not be used in new development projects. They have been maintained internally for backward compatibility only and they will not be documented here nor supported in the future. Furthermore, these obsolete elements will not be displayed by Intellisense and, in Visual C++, will not be inserted inside the wrapper class.
The following is the full list of obsolete properties and methods with the current alternative you should use from now on.
(*) Obsolete starting from version 4
