jQuery Grid Plugin - jqGrid

I have a subgrid with a grid.

In the parent grid I add three buttons to the end of the parent grid ...

 loadComplete: function(){
       ids = jQuery("#grid").getDataIDs();
       for(var i=0;i<ids.length;i++){
           var cl = ids[i];
           be = "<input class='smallinput' type='button' value='Edit' onclick=jQuery('#grid').editRow("+cl+"); /> ";
           se = "<input class='smallinput' type='button' value='Save' onclick=jQuery('#grid').saveRow("+cl+"); /> ";
           ce = "<input class='smallinput' type='button' value='Can'  onclick=jQuery('#grid').restoreRow("+cl+"); />";
           jQuery("#grid").setRowData(ids[i],{actions:be+se+ce})
       }

In the subGridRowExpanded event i set the parent grid columns who have editable: true to false.

If the subGridRowColapsed event i set the parent grid columns who have editable:false to true. The point here is to disable anyone editing a parent grid row until they have completed with the sub grid.

All this works well, the only problem is the editRow, saveRow and restoreRow no longer trigger an inline ediit on the parent rows. Also if I do not expand the subgrid the inline editing works.

Is there a better approach than editable:false on the parent columns, for example: disable the editRow, saveRow and restoreRow buttons!

any ideas?
