Extjs Drag & Drop between two grid

i need to drag from grlRicProd to drop into grlInsOrd

grlIRicProd: .....

id: 'grlRicProd', 
sm: new Ext.grid.RowSelectionModel({ 
    singleSelect: false 
}), 
enableDragDrop: true, ddGroup: 'grlRicProd-dd',
ddText: 'Prodotto Selezionato',

......

grlInsOrd

....

id: 'grlInsOrd', 
enableDragDrop: 
true, ddGroup: 'grlInsOrd-dd', 
listeners: { 
"render": { 
 fn: function(grid) { 
   var ddrow = new Ext.dd.DropTarget(Ext.getCmp('grlInsOrd').getEl(), { 
   ddGroup: 'grlRicProd-dd', // Data come from?? 
   copy: false, 
   notifyDrop: function(dd, e, data) { 
     var sm = Ext.getCmp('grlRicProd').getSelectionModel(); 
     var rows = sm.getSelections(); 
     var cindex = dd.getDragData(e).rowIndex; //cindex IS UNDEFINED! WHY? 
     if (sm.hasSelection()) {
        for (i = 0; i < rows.length; i++) {
            Ext.getCmp('grlRicProd').store.remove(Ext.getCmp('grlRicProd').store.getById(rows[i].id)); //THIS WORKS FINE 
           Ext.getCmp('grlInsOrd').insert(cindex,rows[i]);//ERROR cindex is not开发者_Python百科 defined
        } 
        sm.selectRecords(rows);
      }
  }); 
} 

} }

how can i solve it?? thanks!

See this example and its code:

It works perfectly! You are doing something which isnt required. the copy, creation and removal is all done automatically.
