dhtmlxGrid values


I’m having a dhtmlxGrid. On loading the document, i fill the grid with values from url “url1” in json format. Also i have a button in my window, when clicked fills the grid with values from “url2”. Now i’m creating a new instance of grid in button click, so the old values are replaced. Is there a way to add the values to existing values in the grid when button is clicked? Please reply ASAP.

Please, try to use the following solution:

grid._refresh_mode=[true]; grid.load(url2,""json);
