Creating a link in a DB value

Hi all,
I have a gridview with some DB values, i want to turn that values into link, so the user can click them and get redirect to another page.
I got this:
dr[drEscrever] += String.Format("{0:#.##}", avaliacoes[i].ToString()[j].ToString());

this is to write the values from the DB and i want to add asomething like this:Response.Redirect("~/rh/EditarQualidade.aspx?parameter=" + idAvaliacao);

How can i do that? someone can explain that to me? thanks in advance
