How to display total of recordes in jqxgrid

I have jqxgrid.I am very new to jqxgrid.I want to display total of recordes or values in column. Can any tell me how to do enter image description here

jqxgrid have feature to show aggregates for some column, that aggregates could be 'SUM', 'COUNT', or 'AVERAGE'

you can set the aggregates types when u set the column setting in jqxgrid declaration.

for simple example is like this :

// initialize jqxGrid
        $("#jqxgrid").jqxGrid(
        {
            width: 850,
            source: dataAdapter,     
            showstatusbar: true,
            statusbarheight: 50,
            showaggregates: true,
            columns: [
              { text: 'First Name', columntype: 'textbox', datafield: 'firstname', width: 170 },
              { text: 'Last Name', datafield: 'lastname', columntype: 'textbox', width: 170 },
              { text: 'Price', datafield: 'price', cellsalign: 'right', cellsformat: 'c2', aggregates: ['sum', 'avg'] }
            ]
        });

for custom aggregates, u can learn from this link http://www.jqwidgets.com/jquery-widgets-demo/demos/jqxgrid/aggregates.htm?arctic

for complete documentation for aggregates please check the API's documentation from their documentation.

hope this helps
