Is this functionality available in the current version? How can I turn it on?
Dynamic array formulas and spilled array behavior - Microsoft Support
I see that another spread component vedor has this feature. But I seem not find it in XamSpreadsheet
Hello Niels,
Unfortunately this functionality is not currently supported . It would be a new feature idea for spreadsheet which you can mention for future version at https://ko.infragistics.com/community/ideas/i/ultimate-ui-for-wpf
Thank you in advance to submitting your product idea.
