Solution for this is:
Make sure your resource file placed in the App_LocalResource and try to make sure that your esource key and file is correct like below:
((asp:Literal ID="Literal1" runat="server" meta:resourcekey="Literal1Resource1" Text="(%$ Resources:Default2, HyperLinkFieldResource1.Text %)")(/asp:Literal)<%$ Resources:Default2, HyperLinkFieldResource1.Text %>
Hope This helps!!!!
