hi,

Hello, after populated the grid with a class

<telerik:RadGrid ID="radGridListTypeRoom" runat="server" 
                            AllowPaging="false"  
                            Width="100%" 
                            AutoGenerateColumns="false" 
                            OnDetailTableDataBind="radGridListTypeRoom_DetailTableDataBind">
                            <MasterTableView DataKeyNames="hotelRoomTypeId" DataMember="MasterGrid" Name="TypeRoom" Width="100%">
                                <DetailTables>
                                    <telerik:GridTableView DataKeyNames="hotelRoomTypeId" Name="DetailPrice" Width="100%">
                                         <Columns>
                                            <telerik:GridTemplateColumn HeaderText="Username">
                                                <ItemTemplate>
                                                    <asp:Label ID="lblName" runat="server" Text='<%# Bind("name") %>'></asp:Label>
                                                </ItemTemplate>
                                            </telerik:GridTemplateColumn>
                                        </Columns>
                                    </telerik:GridTableView></DetailTables>
                                <Columns>
                                    <telerik:GridBoundColumn DataField="name" HeaderText="Tipo di stanza">
                                    </telerik:GridBoundColumn>    
                                    <telerik:GridBoundColumn DataField="isAvailable" HeaderText="Disponibilità">
                                    </telerik:GridBoundColumn>                                    
                                </Columns>
                            </MasterTableView>
                            <PagerStyle Mode="NextPrevAndNumeric"></PagerStyle>
                        </telerik:RadGrid>

radGridListTypeRoom.DataSource = hotel.RoomTypes;
radGridListTypeRoom.DataBind();

when fired the event to view the detail (Hierarchy) how can i retrieve the object class?

        protected void radGridListTypeRoom_DetailTableDataBind(object source, Telerik.Web.UI.GridDetailTableDataBindEventArgs e)
        {
            GridDataItem dataItem = (GridDataItem)e.DetailTableView.ParentItem;
 
            RoomType roomType = (RoomType)dataItem.DataItem;
 
            switch (e.DetailTableView.Name)
            {
                case "DetailPrice":
                    {
 
                        break;
                    }
            }
        }

why dataitem.dataitem is null ?

Thanks for the collaboration and sorry for bad eng.
