The EditClose method can be used to close programmatically the currently editor. The Edit method starts editing the focused cell, if the cell has an editor assigned. Use the Editor property of the Column object, or CellEditor property to assign an editor to a cell. The focused cell is determined by the intersection of the focused item and the focused column. Use the FocusItem property to get the handle of the focused item. Use the FocusColumnIndex property to determine the index of the focused column.
