Change Visiblity and Change text for hidden Hyper Link from Code Behind

I know this can be done using javascript but I need simplest way if there is any: I have gridview with following code @aspx page

    <ItemTemplate>
<asp:HyperLink  ID="idLinkBtn" runat="server" Text='<%# Eval("TR") %>' </asp:HyperLink>
<asp:HyperLink  ID="HyperLink1" runat="server" Text='<%# Eval("TR") %>' Visible="false"></asp:HyperLink>

<asp:HyperLink  ID="HyperLink2" runat="server" Text='<%# Eval("TR") %>'  Visible="false" ></asp:HyperLink>
    </ItemTemplate>

How can I access the hidden hyperlinks and set their text and make them visible from code behind? I tried "Find control" method but it is returning null value. Answers appreciated! 

Thanks!

You can use RowDataBound event of GridView.

For example,

void GridView1_RowDataBound(Object sender, GridViewRowEventArgs e)
{
   if(e.Row.RowType == DataControlRowType.DataRow)
   {
      var idLinkBtn = e.Row.FindControl("idLinkBtn") as HyperLink;

      // The as operator will return null if the cast fails,
      // so check for null before you try to use the hyper link
      if(idLinkBtn != null)
      {
          idLinkBtn.Visible = true;
      }
   }
}
