I just encountered a problem with the redo function of the spreadsheet.
Depending on the demo: http://demos.telerik.com/aspnet-core/spreadsheet/index
- Select i.e. cell A3 and press CTRL + C to copy
- Select B3 and press CTRL + V to paste and then the same with B4
- Now press 3 times CTRL + Z to undo all changes
- If you now press CTRL + Y to redo the first paste, nothing happens
