Add an ExportToXlsx option into the native RadGridView exporting. It has been done for WPF (http://docs.telerik.com/devtools/wpf/controls/radgridview/export/export-xlsx) - why not WinForms. This would avoid the pain of having to implement the export using RadSpreadProcessing.
The export provider, which exports to XLSX internally depends on RadSpreadProcessing. It seems the first sentence is somewhat misleading and we will improve it. In both suits the export provider that is responsible for exporting the grid to XLSX depends on RadSpreadProcessing internally (you just need it added as reference) and you don't have to work with the library itself. From there on, you use the convenient API that the export provider features as described in the article I previously provided. Could you please share if this works for you and if it doesn't, what are the reasons for that? Thank you in advance for your time and cooperation.
I specifically stated that I want to be able to export to .xlsx without having to use RadSpreadProcessing. As the first line in the link that I included for WPF states: http://docs.telerik.com/devtools/wpf/controls/radgridview/export/export-xlsx
Hi Jared, this is available in WinForms as well, for quite a while. Here is the documentation on the matter: http://docs.telerik.com/devtools/winforms/gridview/exporting-data/spread-export
