jQuery Grid Plugin - jqGrid

Hello,

in my  web application i am already using jqgrid since version 3.5.

forexample at my search windows when screen loading i am opening jqgrid with no data. after seach parameter entered i make ajax request and with other ajax response grid content has come as json object

so i populate grid with addJSONData metod such as ;

var mygrid = jQuery("#"+objeId)[0];

var data  = {"page":"1","total":0,"records":0,"rows":[{"id":"1","cell":["1-480","1884","BASYAYLA"]},{"id":"2","cell":["2-481","1983","SARIVELILER"]}]};

// data variable has return from ajax request.
mygrid.addJSONData(data);

But when i work with big dataset. there is problem. Grid evulation process taken so many time.

i see at new version there is loadonce and scroll metod.

i try to use these metod but i am not able to success.

How could i use addJSONData, scroll and loadonce at same time.
