[GRID] Sort by first column by default

This must be easy - how to set sorting to first column after grid loads ?

To actually sort rows
    grid.sortRows(0)

To just mark column as sorted
    grid.setSortImgState(true,0,“asc”);

The loading is async, so you will need to use
    grid.load(url,function(){
       grid.sortRows(0);
    });
