                   if (headercommand.First.ToString().ToLower() == "fg")
               {
                   e.Canceled = true;
                  /// GridFilteringItem filter = (GridFilteringItem)e.Item;
                   GridHeaderItem filter= (GridHeaderItem)e.Item;

I reproduced the proposed solution for the filter context menu. ( GridHeaderItem )

case "headercontextmenufilter":

                   Triplet headercommand = (Triplet)e.CommandArgument;
                   Pair command = (Pair)headercommand.Second;

                   if (headercommand.First.ToString().ToLower() == "fg")
                   {
                        GridHeaderItem filter = (GridHeaderItem)e.Item;

                        ((filter["descrizione"].Controls[0]) as TextBox).Text = ((filter["fg"].Controls[0]) as TextBox).Text;
                        command.Second = "descrizione";
                        filter.FireCommandEvent("Filter", new Pair(command.First, "descrizione"));
                   }

                   break;

but I can not apply this solution, because it slows

thank you anyway
