I’m experiencing the same issue… the export works fine for pdf. For csv it works but I receive an empty file while for excel I’m getting “q.toISOString is not a function”, as well.
I have a license and I’m using the save-file.php file locally and the last jqwidgets version.
Could it be connected to empty cells? I mean, cells with value = ”; ? or again could it be an issue generated by using cellsrenderer? By exporting the PDF, I receive empty cells for value = ” even if the cellsrenderer returns something like: return ‘<div style=”text-align: left; margin-top: 5px; margin-left:5px; z-index:1000;”> x </div>’;
Could you provide an example of grid exporting by including the cellrenderer and some empty cells?
Thanks!
