hi
Try this..
<asp:HyperLink ID="lnkDetailsPage" Text="click here" runat="server" NavigateUrl='<%# "~/YellowPages/YellowDetailView.aspx?CustomerId=" + HttpUtility.UrlEncode(Eval("CustomerId").ToString()) %>'>
</asp:HyperLink>
Text="click here"
whenever you are using Hyperlink you should assign the
Text
value.
if the
Text
value is empty , then the link wont appear on the screen.
