Make asp:HyperLink the list items in an asp:DataList

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'.
    Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it   
    originated in the code.

Is artist.aspx any result set in your dataset or a web page of your application ? If web page then do you really need to use Eval for this ? — Amit Verma

Yes, artists,aspx lists artists and albums.aspx will list the artist and their albums. I'm not sure about Eval. I used an example I found. — sflat

Try it this way.

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

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