Hi

I'm new to asp.net and c# and I've got stuck on an apparently simple
problem:

I'm trying to make a HyperLink dynamically visible/invisible.

This is the HTML:

<asp:HyperLink Runat="server" Text="Back"
NavigateUrl='HeadingList.aspx' Visible='<%=isNotTop()%>' />

This is the in the .cs file:
                public string isNotTop()
                {
                        return ("false");
                }

I get the error message:
<%=isNotTop()%> is not a valid value for Boolean.

I've tried getting isNotTop() to return a boolean but it doesn't help.

I've done something similar within a DataList using <%#...%> and it's
worked OK.

Can someone guide me in the right direction here?

Cheers
