;

add afteredit listener editor object , in listener call setdisabled(true) method on id textfield this:

var idtextfield = ext.create({     xtype : 'textfield',     allowblank : true });  var editor = new ext.ux.grid.roweditor({     savetext: 'update',     listeners: {         afteredit: function(){             idtextfield.setdisabled(true);         }     } });

and modify existing code replacing old textfield above mentioned:

... {   header : "id",   width : 120,   sortable : true,   dataindex : 'id',   renderer: function (value, metadata, record, rowindex, colindex, store) {                 return  gettooltip(value, metadata, record, rowindex, colindex, store);   },   editor : idtextfield } ...

so changed editor property.
