Weird исключение в LinkButton в DataList

Question

я написал эту DataList:

 <div class="story" runat="server"> 
    <asp:DataList ID="DataList2" runat="server" Height="16px" Width="412px"> 
        <SeparatorTemplate> 
        <hr /> 
        </SeparatorTemplate> 
       <ItemTemplate> 
        <asp:LinkButton ID="LinkButton1" runat ="server" Text='<%# Eval("Name") %>' PostBackUrl='<%#Eval("Url")%>' />   
        <br /> 
        Description: 
        <asp:Label ID="new" Text='<%#Eval("Description") %>' runat="server" />     </ItemTemplate> 
       </asp:DataList> 




     </div> 

Это вызывает исключение сказать, что LinkButton должен быть помещен в тег, который содержит RUNAT = «сервер», хотя она существует. Вот след

Answer 1

Он должен быть в form тег <form runat="server"></form> с атрибутом RUNAT сервера.

Следующая ссылка говорит о атрибуте Runat сервера:
