#128 Elements of classes are hided

[Gustavo Furtado]

Hi
I´m new on ZedGraph. It´s a wonderfull tool, but I´m in a strange situation: some elements of classes don´t appear on Intellisense (VS2010, C#) and even causes compilation error. For example: ZedGraphControl doesn´t has PointValueEvent event (it doesn´t appear as an option element in popup).
Am I forgetinng something? I´m using V5.1.5.
Sorry if it´s not the right place for this doubt.
