Does your sql code does sort it? it check on the value of (sortname/$sidx) param, and pass it as the attribute to ORDER BY clause. So in your case it was set to ID,does ID a valid column name in your DB?

I made simple jqGrid

but  reordering doens't work. even if I click the header. the reordering doesn't work. 

what should I check ? 

colModel:[

{name:'ID',index:'ID', width:100,align:"center"},

{name:'Brand',index:'Brand', width:90},

{name:'BrandId',index:'BrandId', width:100},

caption:"JSON Example"

viewrecords: true,

sortorder : 'desc',

sortname: 'ID',

pager: '#pager2',rowList:[10,20,30],rowNum:10,],
