Sorry, there was some misunderstanding. I need only to implement customaggregate
please find the jsfiddle in below link
fiddle
this fiddle will not give result because of cell formatting cellsformat: “HH:mm” in last column.
if we remove cellsformat: “HH:mm” from jqxgrid, it will show aggregate value. that means aggregate row takes cell format. i need to display a string in aggregate cell
