使 asp:HyperLink 成为 asp:DataList 中的列表项

Question

I have searched for a solution but something is missing and I don't know what it is. All of the code below works fine except asp:HyperLink gives me an error. I only need one

column with links for each Artist. The current code does fill a one column table. But I need each item to be a link.

Code:

<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>

Error:

DataBinding: 'System.String' does not contain a property with the name 'aspx'.

Answer 1

试试这个方法。

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

Answer 2

Thomson Mixab gave the answer in code. Which is: <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# Eval("Artist") + ".aspx" %>' Text='<%# Eval("Artist") %>' />
