My goal is to handle the exportExcel event, invoke the export saveAsExcel function, then pass the excel data to the server as a base64 string.
However if the spreadsheet contains images, and unhandled error occurs in the kendo script, which I have managed to track down via the unminified kendo.all.js and it seems to occur at this place:
'images is not defined' is the error message.
I've created Dojos which illustrate and reproduce the problem.
Clicking on the "Export" button will trigger the excel export:
