How to Set Hyperlink href value from Database Using C# in ASP.Net

hi

I put below code in page:

using (SqlConnection conn1 = General.GetConnection())
{
    using (SqlCommand _cmd1 = General.GetCommand("DownloadurlToken", conn))
    {
        conn1.Open();
        SqlDataReader _drA = _cmd1.ExecuteReader();
        while (_drA.Read())
        {
            HPtemporary.HRef = string.Format("http://digimaster.ir/downloads/{0}", _drA["DownloadToken"]);
            HPtemporary.InnerText = Page.ResolveClientUrl(HPtemporary.HRef);
        }
     }
}

and:

<a ID="HPtemporary" runat="server"></a>

now I want use <a> tag in grid view:

<asp:TemplateField ItemStyle-Width="24px" ItemStyle-VerticalAlign="Middle">
  <ItemTemplate>
     <a ID="HPtemporary" runat="server" ></a>
  </ItemTemplate>
</asp:TemplateField>

and:

if (_drA.HasRows)
{
   GridView1.DataSource = _drA;
   GridView1.DataBind();
}

but how I can use below code in gridview:

HPtemporary.HRef = string.Format("http://mysite.com/downloads/{0}", _drA["DownloadToken"]);
HPtemporary.InnerText = Page.ResolveClientUrl(HPtemporary.HRef);

Best Regards
