Answer 1

Suppose in the Master page you've got something like this:

<a href="Student.aspx">Students</a>

add runat="server" and id property for the tag

<a href="Student.aspx" id="studentLink" runat="server">Students</a>

Then in the Page_Load event of the BooksInformation.aspx make sure the user is logged in and hide the links:

var studentLink = Master.FindControl("studentLink") as HtmlControl;
studentLink.Visible = false;
