jQuery Grid Plugin - jqGrid

I'm trying to disable sortablerows functionality from a grid. I'd like to have the ability to toggle on/off the sortablerows functionality. Enabling the feature is pretty straightforward:

jQuery("#list").jqGrid('sortableRows', {
     update: function(event, ui) { updateOrder() }
});

But disabling the feature has proven to be a little bit harder. I've consulted the UI Integrations where

is documented in the jqGrid Wiki:

http://www.trirand.com/jqgridw.....ui_methods

And found that "The method is fully compatible with jQuery UI sortable widget." So I ventured off to the jQuery UI sortable documentation and found this:

http://jqueryui.com/demos/sortable/

jQuery("#list").jqGrid('sortableRows', {disabled: true});

The code above simply disables the rows. So I moved onto the

method:

jQuery("#list").jqGrid('sortableRows', {destroy: true});

but that doesn't do anything. Based upon the documentation the

method seems to be exactly what I need, so maybe my syntax is wrong but I can't seem to get it to work.

Does anyone have experience with this same issue?
