The ParamMapEventArgs class derives from EventArgs and is used by the Xceed Chart for WinForms server control when it generates server side events. In a nut shell the ParamMapEventArgs implements a simple map allowing the server control to pack the parameters passed with the event in a single object. You extract values from the map by using the ParamMapEventArgs methods that also perform type conversion. You can also access the map with the help of the Params property which returns a System.Collections.SortedList object.
