Hi Fritz,
Thank you for interesting in Syncfusion products.
We have checked the reported query “Adding Spreadsheet to Spreadsheet Ribbon Ctrl” at our end. In order to achieve your requirement you can set the Spreadsheet control to SpreadsheetRibbon using Spreadsheet API through designer.
We already documented the same in the following user guide documentation.
Note
To make an interaction between Ribbon items and Spreadsheet, bind the Spreadsheet as DataContext to the SpreadsheetRibbon
We have attached the tested sample for your reference and you can download the same from the following location.
