is there any diffrence between load method and parse method?

Hi I am developing grid with DHTMLX.
Thanks for your previous answer.

I tried to use load method load(jsonstring,“json”), but at display this is not working.
Instead of load, I use parse method like below, it is working. is there any between former and latter? If I want to use load mehtod load(jsonstring,“json”), How can I convert to the logic?
Can you let me know ?

var myGrid2;
function doOnLoad2() {
myGrid2 = new dhtmlXGridObject(‘gridbox2’);
myGrid2.setImagePath("<c:url value="/dhtmlxSuite/codebase/imgs/" />");
myGrid2.setHeader(“선택,그룹코드,공통코드,공통코드명,공통코드 설명,속성1,속성2,속성3,속성4,정렬순서”);
myGrid2.attachHeader("#rspan,#text_filter,#select_filter,#numeric_filter,#rspan,#rspan,#rspan,#rspan,#rspan,#rspan");

myGrid2.setInitWidths(“50,150,150,150,150,150,150,150,200,200”);
myGrid2.setColAlign(“center,left,left,left,left,left,left,left,left,left,right”);
myGrid2.setColTypes(“ch,co,ed,ed,ed,ed,ed,ed,ed,ed”);
//myGrid2.getCombo(1).put(2,2);
myGrid2.setColSorting(“str,str,str,str,str,str,str,str,str,str”);
myGrid2.init();
myGrid2.enableAlterCss(“even”,“uneven”);
//myGrid2.parse(data,“json”);
}
myGrid2.parse(JSON.stringify(data),“json”);

data is

load() method should be used for loading the data from the external file.
