Custom export/print buttons not working

[Benjamin]

I can't use the built-in command items and have defined my own command item template.  However, all that happens when I click export or print is the command item header, footer, and paging disappear.  I do not get a excel or pdf file.  Here is my code.  What should I do different?  Thanks!

Hi,

You can resolve this issue by disabling AJAX when exporting:
https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/how-to/Exporting/export-from-ajaxified-grid

I hope this will prove helpful.
