jQuery Grid Plugin - jqGrid

Guys,

I am having an issue scrolling to specific row with virtual scrolling, i have give the options for jqgrid :-

scroll: true,

scrollrows: true,

the following lines does not scroll to specific row :-

var gridResults = $("#grid_results");

gridResults.setSelection(id, false);

This works absolutely fine if paging is enabled. Can someone help as I am struggling since 2 days with this and could not find an alternative ?

Actually I have also tried manually navigating to the page and show the selected row as :-

gridResults.setGridParam({page: value});

gridResults.trigger("reloadGrid");

gridResults.setSelection(id, false);

this navigates to the page but data is not displayed at all.

Any help in this would be very much appreciated 

Thanks

Saif
