Thank you for writing.
Currently, Telerik UI for WinForms suite does not contain Spreadsheet UI control. However, we already have a feature request logged in our feedback portal. You can track its progress, subscribe for status changes and add your vote/comment to it on the following link - feedback item.
You can refer to our Demo application >> Grid View >> Spread Sheet
example demonstrating how to display data in Excel style.
I hope this information helps. Should you have further questions, I would be glad to help.
