奇怪的例外中的LinkBut​​ton DataList控件

Question

我寫了這個數據列表：

 <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> 

它提出了一個異常說LinkBut​​ton的必須放置在包含RUNAT =「服務器」，但它存在一個標籤。 這裏是跟蹤

Answer 1

它是在一個form標籤​​帶有runat服務器屬性。

有關RUNAT服務器屬性下面的鏈接會談：
