           <asp:Button runat="server" ID="btnFattura" Text="Fattura"

protected void rgrFatturazione_DetailTableDataBind(object source, GridDetailTableDataBindEventArgs e)
       {
           GridDataItem dataItem = (GridDataItem)e.DetailTableView.ParentItem;
           if (e.DetailTableView.Name == "Commessa")
           {
               string Cliente2 = dataItem["Codice Cliente"].Text;
               e.DetailTableView.DataSource = this._LoadCommesse(int.Parse(Cliente2));
           }
           else
           {
               string Cliente3 = dataItem["Cliente Commessa"].Text;
               string Commessa = dataItem["Commessa"].Text;
               e.DetailTableView.DataSource = this._LoadRapportini(Commessa, int.Parse(Cliente3));
           }
       }
}

i try this but doesn't work..

protected void btnFattura_Click(object sender, EventArgs e)
        {
            foreach (GridDataItem clienti in rgrFatturazione.MasterTableView.Items)
            {
                foreach (GridDataItem commesse in clienti.ChildItem.NestedTableViews[0].Items)
                {
                    foreach (GridDataItem rapportini in commesse.ChildItem.NestedTableViews[0].Items)
                    {

                    }
                }
            }
        }

thanks!!

Hello Matteo,

More information about how you can loop through all detail tables/items in RadGrid is available in the help article below:
Traversing detail tables/items in Telerik RadGrid

Give it a try and let me know if it helps.
