PDF Export field width

Where would I set the field width for PDF export.All my columns export as the same width so when a field has more chracters than the coumn width it wraps.
I’ve tried field width in aspm, also size and max length.

You can try adding the following codes in Page_Load server event:ExportColumnWidths = new float { 100, 200, etc… }; // Set column widths

This does not work, I’ve tried every possible combination. incl with 100f, 200f etc…
Is there another server event to try.
Thanks

Try Table_Load or Page_Exporting
