I've started with your excellent RadSpreadsheet "First Look" SDK example so I have a dialog that looks a lot like Excel. I can fill in my data nicely.
But what I'd like to do is to add buttons to the spreadsheet. Clicking those buttons would open small modal forms for calculating data which I'd use to update the sheet. I do not see that I can put a button into a cell. Is it possible to put a button onto the spreadsheet?
