使 asp:HyperLink 成为 asp:DataList 中的列表项

问题描述

我已经寻找了解决方案，但缺少一些东西，我不知道它是什么。下面的所有代码都可以正常工作，除了 asp:HyperLink 给我一个错误。我只需要一个

带有每个艺术家链接的列。当前代码确实填充了一个单列表。但我需要每个项目都是一个链接。

代码：

<asp:DataList ID="DataListArtists" runat="server" DataSourceID="sqlDataSourceArtists">
    <ItemTemplate>  
        <table class="table">  
            <tr>  
                <th colspan="2">  
                    <b>  
                    <%# Eval("Artist") %></b>  
                </th>  
            </tr>  
        </table>
        <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# Eval("Artist.aspx") %>'  Text='<%# Eval("Artist") %>' />
        </asp:HyperLink>
    </ItemTemplate>
</asp:DataList>

错误：

    originated in the code.

解决方法

试试这个方法。

<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# Eval("Artist") + ".aspx" %>'  Text='<%# Eval("Artist") %>' />
