How to display username in a name control

I have a main page containing loginview content that appears on all subsequent pages based on the main page. I have a username control also nested in the loginview to display the username at login. The code to enter the system from the main page is displayed as follows:

<div class="loginView">
                <asp:LoginView ID="MasterLoginView" runat="server">
                    <LoggedInTemplate>
                        Welcome <span class="bold"><asp:LoginName ID="HeadLoginName" runat="server" /> 
                            <asp:Label ID="userNameLabel" runat="server" Text="Label"></asp:Label></span>!
                    [ <asp:LoginStatus ID="HeadLoginStatus" runat="server" LogoutAction="Redirect" LogoutText="Log Out" LogoutPageUrl="~/Logout.aspx"/> ]
                        <%--Welcome: 
                        <span class="bold"><asp:LoginName ID="MasterLoginName" runat="server" /> </span>!--%>                       
                    </LoggedInTemplate>
                    <AnonymousTemplate>
                        Welcome: Guest
                        [ <a href="~/Account/Login.aspx" ID="HeadLoginStatus" runat="server">Log In</a> ]
                    </AnonymousTemplate>

                </asp:LoginView>
                <%--&nbsp;&nbsp; [&nbsp;<asp:LoginStatus ID="MasterLoginStatus" runat="server" LogoutAction="Redirect" LogoutPageUrl="~/Logout.aspx" />&nbsp;]&nbsp;&nbsp;--%>

            </div>

Since VS2010 starts up with the default login page in the accounts folder, I did not think it was necessary to create a separate login page, so I just used the same login page. Please find the login code below:

 <asp:Login ID="LoginUser" runat="server" EnableViewState="false" RenderOuterTable="false">
    <LayoutTemplate>
        <span class="failureNotification">
            <asp:Literal ID="FailureText" runat="server"></asp:Literal>
        </span>
        <asp:ValidationSummary ID="LoginUserValidationSummary" runat="server" CssClass="failureNotification" 
             ValidationGroup="LoginUserValidationGroup"/>
        <div class="accountInfo">
            <fieldset class="login">
                <legend style="text-align:left; font-size:1.2em; color:White;">Account Information</legend>
                <p style="text-align:left; font-size:1.2em; color:White;">
                    <asp:Label ID="UserNameLabel" runat="server" AssociatedControlID="UserName">User ID:</asp:Label>
                    <asp:TextBox ID="UserName" runat="server" CssClass="textEntry"></asp:TextBox>
                    <asp:RequiredFieldValidator ID="UserNameRequired" runat="server" ControlToValidate="UserName" 
                         CssClass="failureNotification" ErrorMessage="User ID is required." ToolTip="User ID field is required." 
                         ValidationGroup="LoginUserValidationGroup">*</asp:RequiredFieldValidator>
                </p>
                <p style="text-align:left; font-size:1.2em; color:White;">
                    <asp:Label ID="PasswordLabel" runat="server" AssociatedControlID="Password">Password:</asp:Label>
                    <asp:TextBox ID="Password" runat="server" CssClass="passwordEntry" 
                        TextMode="Password"></asp:TextBox>
                    <asp:RequiredFieldValidator ID="PasswordRequired" runat="server" ControlToValidate="Password" 
                         CssClass="failureNotification" ErrorMessage="Password is required." ToolTip="Password is required." 
                         ValidationGroup="LoginUserValidationGroup">*</asp:RequiredFieldValidator>
                </p>
                <p style="text-align:left; font-size:1.2em; color:White;">
                    <asp:CheckBox ID="RememberMe" runat="server"/>
                    <asp:Label ID="RememberMeLabel" runat="server" AssociatedControlID="RememberMe" CssClass="inline">Keep me logged in</asp:Label>
                </p>
            </fieldset>
            <p class="submitButton">
                <asp:Button ID="LoginButton" runat="server" CommandName="Login" Text="Log In" 
                    ValidationGroup="LoginUserValidationGroup" onclick="LoginButton_Click"/>
            </p>
        </div>
    </LayoutTemplate>
</asp:Login>
