Hi,
What is the best way to bind a detailtable with the same record as the master?

    
                <telerik:radgrid  
        
                    ID="radGridBusinessRegister"  
        
                    runat="server"  
        
                    allowpaging="True"  
        
                    allowsorting="True"  
        
                    gridlines="None"  
        
                    onneeddatasource="radGridBusinessRegisterNeedDataSource" 
        
                    OnDetailTableDataBind="radGridBusinessRegisterDetailTableDataBind" 
        
                    Skin="SkyBlue" 
        
                    ShowGroupPanel="false" 
        
                    AutoGenerateColumns="false"> 
        
                    <MasterTableView  
        
                        DataKeyNames="ID"  
        
                        Name="Master"> 
        
                        <Columns> 
        
                            <telerik:GridBoundColumn UniqueName="Name" DataField="Name" HeaderText="Namn" /> 
        
                            <telerik:GridBoundColumn UniqueName="Phone1" DataField="Phone1" HeaderText="Telefon" /> 
        
                            <telerik:GridBoundColumn UniqueName="Email" DataField="Email" HeaderText="E-post" /> 
        
                        </Columns> 
        
                        <DetailTables> 
        
                            <telerik:GridTableView 
        
                                DataKeyNames="ID" 
        
                                AutoGenerateColumns="true" 
        
                                ShowHeader="false" 
        
                                Name="Detail" 
        
                                CommandItemDisplay="None"> 
        
                                <ItemTemplate> 
        
                                    <h1>Detaljsida för <%# Eval("Name") %></h1> 
        
                                    <p><%# Eval("Description") %></p> 
        
                                </ItemTemplate> 
        
                            </telerik:GridTableView> 
        
                        </DetailTables> 
        
                    </MasterTableView> 
        
                </telerik:radgrid>

    
            protected void radGridBusinessRegisterDetailTableDataBind(object source, GridDetailTableDataBindEventArgs e) 
        
                    { 
        
                        if (e.DetailTableView.Name == "Detail") 
        
                        { 
        
                            int id = (int)e.DetailTableView.ParentItem.GetDataKeyValue("ID"); 
        
                            e.DetailTableView.DataSource = CompanyService.GetById(id); 
        
                        } 
        
                    }

This is not working because the datasource needs a different kind of data type.
Error: Data source is an invalid type. It must be either an IListSource, IEnumerable, or IDataSource.

I guess I don't need the round trip to the database either!
