jQuery Grid Plugin - jqGrid

Hi,

I am using virtual scrolling with loadonce:false, datatype:json. I have 140000 rows, every page I send 100 rows. All works fine i.e. as I scroll I see new requests going to server with appropriate value of page query parameter. So I scroll to page 3, then I trigger refreshGrid but then the request goes with page=1, instead of page=3, i.e. page is getting reset. What can be done so that refreshGrid trigger requests the same page and retains the scroll location. Somewhere in the code inside bind of refreshGrid, I forced it to execute populate instead of populateVisible and it kind of worked, but I am not sure if that the good answer.
