control_data - Control data
In order to make use of different control specific features not supported by the GUI frame work, specific control options can be defined here . The way to pass those options depends on the implementation of the user control, which receives all optional settings in a single options string. In general, it is suggested to use keyword options separated by line breaks, which increases readability for optional settings. Options supported by a specific user control have to be defined in the user control documentation, which should be delivered with the user control installation.
