I have some questions about the spreadsheet widget in Kendo:
1. How can I get the currently selected range of cells? The sheet.activeCell method seems just to return the primary selected cell.
2. How can I register an event which triggers if the selection of cells has changed? Currently I use the "render" event, but this triggers more often than I need it to.
3. The "change" event does not trigger, if the undo method is used (which changes some values). How can I trigger the change method including the changed range/values?
Thank you for your help + Best regards
