it states in jqgrid documentation that the code below should allow local sorting with server side paging;
the grid data disappears on paging; this question has been asked before with no clear answer - suggestions to use loadonce:true means that paging is turned off - I need paging
EDITED LATER TO SHOW COMPLETE html page and json response
(Im now running this from a php/mysql backend).
