Changing ContentPlaceHolder's content dynamically

Question

I have an index page as a content page and at the top of it i have a content place holder like this.

    <asp:Content ID="Content3" ContentPlaceHolderID="logProcessHolder" runat="server">
        <p class="header-link"><a href="LoginFormContainer.aspx">login</a>&nbsp;or&nbsp;<a href="RegisterFormContainer.aspx">create an account</a></p>
    </asp:Content>

I want to change its content when users login. After login i want to put user name instead of these links. I have my login method already, just want to know how can i make this without using an another content page ? or is it a logical solution for me ? Should i use an another content page as a home page ?

Answer 1

I would wrap your options in asp:Panels or use the LoginView control as epaezr has done

<asp:Content ID="Content3" ContentPlaceHolderID="logProcessHolder" runat="server">
   <asp:Panel ID="pnlAnonymous" runat="server">
    <p class="header-link"><a href="LoginFormContainer.aspx">login</a>&nbsp;or&nbsp;<a href="RegisterFormContainer.aspx">create an account</a></p>
   </asp:Panel>
   <asp:Panel ID="pnlVerified" runat="server">
       <asp:Literal ID="litUserName" runat="server" />
   </asp:Panel>
</asp:Content>

Then in your code behind

protected void Page_Load(object sender, EventArgs e)
{
    if (Request.IsAuthenticated)
    { 
        pnlAnonymous.Visible = false;
        pnlVerified.Visible = true;
        litUserName.Text = Context.User.Identity.Name;
    }
    else
    {            
        pnlAnonymous.Visible = true;
        pnlVerified.Visible = false;
    }
 }

You don't have to use panels. You could also HTML elements and access them in the code-behind by giving them an ID and a runat="server" attribute. E.g: <p ID="loginLinks" runat="server" class="header-link">...etc...</p> where you could change the visibility with loginLinks.Visible
