Hi ArunKumar,
Export to PDF is not supported by our Grid. In addition, if you have not hosted the save_file.php on your server and updated the “exportdata” method url parameter to point to the save_file.php hosted on your server, the maximum upload size which we allow on our server is 2MB as we use save_file.php to demonstrate only how the feature works. In short, to export large data sets, you have to host the save_file.php used in the exporting on your server and increase its maximum upload size.
Best Regards,
