As I know you can't use "<%= %>" with server controls. So you can:

1. Leave it as a server control and follow Andrew Hare's (or similar) answer.
2. Use client control: "<a />" and "<%= %>" should work.

Your ASP.NET code should look like this:

<asp:HyperLink ID="link1" runat="server" NavigateUrl=''>Equipamentos</asp:HyperLink>

And then add this in code behind:

this.link1.NavigateUrl = string.Format("Equipamentos.aspx?ID_Cliente={0}", Request.QueryString["ID_Cliente"].Trim());

You are not going to be able to set the NavigateUrl of the link in this way. Try something like this:

<asp:hyperlink 
    ID="link1" 
    runat="server">Equipamentos</asp:HyperLink>

And then in your codebehing or a script tag do this:

link1.NavigateUrl = "Equipamentos.aspx?ID_Cliente=" 
    + Request.QueryString("ID_Cliente").Trim().ToString();

The

<%@ %>

tags are for directives, such as registering controls. You need a 

<%= %>

tag, which is called a code evaluation block.

Something like 

<%= (5+5).ToString() %>

is what you need - try your code in there.

Gah, my eyes! Try doing this in code behind instead:


link1.NavigateUrl = "Equipamentos.aspx?ID_Cliente=" & Request.QueryString("ID_Cliente").Trim().ToString()

You have to use "&" instead of "+" because this is VB.NET, not C#.

Try this instead : 

<asp:hyperlink ID="link1" runat="server" 
  NavigateUrl='<%= ("Equipamentos.aspx?ID_Cliente=") 
  + Request.QueryString("ID_Cliente").Trim().ToString() %>'>
  Equipamentos</asp:HyperLink>
