Cancels editing of the active cell.
The method deactivates the active cell editor and clears its value. Use the ASPxClientSpreadsheet.ApplyCellEdit method to deactivate the editor and commit the editor’s value to the active cell.
If the cell editor is not activated by an end-user, the method is not in effect. You can indicate when a cell editor is activated by subscribing to the ASPxClientSpreadsheet.CellBeginEdit event.
