Hello, is there a way to implement load on demand on spreadsheet? or load data while scrolling?

I'm using kendo spreadsheet to display big files, with no edit/save functionality. 

Loading the entire file on json can be very difficult when the json size is 30MB+.

Hello Massimo,

The Spreadsheet currently does not support load on demand/while scrolling features. I would suggest logging a feature request about them in our Feedback Portal, as it will help us track the interest towards them from other users.

Let me know if you have any further questions.

Regards,
Martin
