I see that as promised for the Q3 3016 release, the kendoSpreadsheet now has support for defined names in the UI, and that these names are preserved in the client-side toJSON() method of the kendoSpreadsheet.
Is there any chance we could get support for defined names in the Telerik.Web.Spreadsheet.Workbook object? We've tried
Telerik.Web.Spreadsheet.Workbook.Load(Stream input, string extension)
but any defined names in the source are stripped out. I guess this is because the Telerik.Web.Spreadsheet.Workbook doesn't even have a public Names collection. This issue also prevents a client-generated Workbook from being passed to an MVC method: the MVC binder simply doesn't map properties that aren't public.
The net result is that developers can't take an XLSX file from the file system and render it accurately in the kendoSpreadsheet UI, nor can they round-trip it.
