from MSDN : By default, the ControlStyles.StandardClick and ControlStyles.StandardDoubleClick style bits are set to false for the Button control, and the MouseDoubleClick event is not raised.

1) Works on Single Click. 2) Derive from Button and override controlstyle if neccessary or possible when double click event is required on button.
