Because no similar TDrawGrid controls, c # in Delphi TDrawGrid design as an ActiveX control, in c # can use, but some types and events in c # show not to come out, such as a mouse selected range Selection, because I want to get:
MyGrid. Selection. Left
MyGrid. Selection. Top
MyGrid. Selection. Right
MyGrid. Selection. Bottom

I can define an attribute Selection, but I don't know what type, it belongs to TGridRect Delphi, the essence of TGridRect is Record type, so in OLE specification, this property is of type?
