In the release that should be out in the next few days, there are two click events in addition to the standard Control.Click event. They are GridControl.CellClick and GridControl.CellButtonClick.
CellClick will be hit when you click in a cell and don't hit a cell button. The EventArgs include the row and col as well as the mouseeventargs of the click. The CellButtonClick occurs when you click a cell button. The eventargs include the row and col and buttonindex.
You can handle these events at the form level, or you can catch then in your derived cell controls as the Grid member is known down in the renderer.
You can catch a CellClick event in a static cell. Inyour renderer contructor, you can use code such as
this.Grid.CellButtonClicked += new GridCellButtonClickedEventHandler(ButtonClicked);
to hook a handler. In this case, we hook the CellButtonClick.
