cbsEllipsisThis editor style is the most generic one. When used, a button appears in the editing cell and programmers could use the OnEditButtonClick grid event to detect when the user has pressed the button and take any action programmed for such a cell. For example a programmer could use this editor style to pop up a calendar dialog to allow the user easily to select a specific date. Other possibilities could be to show a file open dialog to find files, a calculator so user can enter the numeric result of calcs, etc.OnEditButtonClick is just a notification, to find out in which cell a button has been clicked by taking a look at the grid.Row and grid.Col properties.
at least the ellipse should work.
