Please add support for protected worksheets and protected workbooks.

Expose a way to know which cells are selected, or even better, read the values of the selected cells.

I would like to be able to save the data in the spreadsheet on an OnChange event when the data in a cell is changed. I don't see any event like this on the control and am wondering if this is something planned for the future.

In Excel, you can add a dropdown to edit the value of a cell. I want the same behavior in the Spreadsheet component.
