How to disable link button if GridView is not present in a page

I have Link Button to Export to excel in Master page. Since  I have placed it in master page I can see Export link button in every page. I need to disable link button where gridview is not present in a page.

I thing using Enabled property we can do. How to proceed. Is there any other way to do it.

<asp:LinkButton ID="LinkButtonExport" Text="Export to Excel" runat="server" OnClick="LinkButtonExport_Click" />
