How do i display user name in loginview control on the master page from login page?

[selasedaniweb]

The first paragraph of the code above is the loginview control that resides in my Masterpage.

the second paragraph is the login page.
where i inserted a login control and writes the code for user authentication

the third paragraph is the code that processes the user authentication and the redirection to the resultant page.

the problem am having is the user name and the logout text does not appear after the page has been redirected. where could i be going wrong?

<div class="loginView">
                    <asp:LoginView ID="MasterLoginView" runat="server">
                        <LoggedInTemplate>
