fastforward1,

If you install jQuery, you can do something like this to swap two rows:

var grid = igtbl_getGridById(gridId);
var row4 = grid.Rows.getRow(4); // this is one way of getting your row
var row2 = grid.Rows.getRow(1);

$(row4.Element).insertBefore($(row2.Element));

or

$(row4.Element).insertAfter($(row2.Element));

Hope this is an OK interim solution for you.
