grid.enableSmartRendering(true) not working

I’m having a dhtmlxgrid. I’m having more than 10k records and it takes more time for the grid to load data. So, i added the “dhtmlxgrid_srnd.js” file in my project and the line grid.enableSmartRendering(true) in my code. But when i run my project, the error "Uncaught TypeError: Object # has no method ‘enableSmartRendering’ occurs. How to solve this issue?

Thanks in advance.

Please, make sure that the path to a dhtmlxgrid_srnd.js is defined correctly.
