将空列表绑定到ASP.NET中的ListView控件

Question

I have an empty list object ( lstPersons ) that I'm binding to a ListView control ( lvPersons ). Since lstPersons is empty, it seems to never generate the ul in html. Is there a way to still force the html ul list to render even though lstPersons is empty? Basically rendering an empty ul, and preferably without having to change the LayoutTemplate?

<asp:ListView ID="lvPersons" runat="server" ClientIDMode="Static">                            
    <LayoutTemplate>                        
        <ul id="ulPersons" runat="server" ClientIDMode="static">
            <li id="itemPlaceholder" runat="server"></li>
        </ul>
    </LayoutTemplate>            
    <ItemTemplate>                                                                                    
        <li>                
            <asp:Label ID="lblName" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "Name")%>'></asp:Label>                                                                                                                                                                                                                            
        </li>                         
    </ItemTemplate> 
</asp:ListView>    


List<Person> lstPersons = new List<Person>();
lvPersons.DataSource = lstPersons;
lvPersons.DataBind();

Answer 1

The list exists, but there are no items in it. So if you want something to show up you need to add an empty Person to the list before binding it to the ListView.

List<Person> lstPersons = new List<Person>();

lstPersons.Add(new Person());

lvPersons.DataSource = lstPersons;
lvPersons.DataBind();
