Welcome all,
I have another problem width a grid (i've ever problem width them XD),
when i click width the right key on a record of the grid, i open a menuto decide if modify o delete that record.
And this is ok. My problem is : how can i catch the data from the row grid??

this is my code
Code:
var grid = new Ext.grid.GridPanel({
    title : 'Elenco Pratiche',
    id : 'grid_users',
    autoFill      : true,
    stripeRows: true,
    stateful: true,
    autoscroll:true,
    autoSizeColumns: true,
    autoExpandColumn: 'utente_as',
    width : Ext.lib.Dom.getViewportWidth() - 60,
    height: Ext.lib.Dom.getViewportHeight() - 185,
    store : this.store_users,
    colModel : colModel,
    selModel : selModel,
    viewConfig: {
        forceFit:true,
        enableRowBody:true,
        showPreview:true,
    },
    listeners : {
      rowcontextmenu  : function(thisGrid, rowIndex, evtObj) {
        evtObj.stopEvent();
        this.selModel.selectRow(rowIndex);
        GridUsersMenu.showAt(evtObj.getXY());
        //alert('sono a destra');
      },
    },
    // paging bar on the bottom 
    bbar:  {
      xtype : 'paging',
      //id : 'StandardGridPagingToolbar',
      store: store_users,
      pageSize : 25,
      displayInfo : true
    },

    loadMask: { msg: 'Caricamento dati in corso...', store: store_users }
  });
and this is the code of menu
Code:
var GridUsersMenu = new Ext.menu.Menu ({
        id : 'StandardGridContextMenu',
        items            : [
             {     text      : 'Modifica',
                iconCls   : 'icon-pencil',
                handler   : modifica
            }
            ,{    text      : 'Cancella',
                iconCls   : 'icon-delete',
                //handler   : StandardGridDelete
            }
          ]
  });
    
  function modifica(clickedItem, record){
    console.log(clickedItem);      
  }
thank you all for the support and sorry for my english
