Spreadsheet is a nice addition to the Kendo UI framework.
After running the samples and reading the documentation, I could not find a way to lock cells and prevent user changes especially to protect formulas. Frozen rows and columns do not seem to achieve the same. Take the demos and consider the invoice, would you implement it as a spreadsheet if you could not lock the tax rate and total?
If there is a way to lock cells, please advise, otherwise please implement before RTM.
