Header ---- .ascx file - Can't be displayed properly

Question

Hi,

    I use .ascx file for Header alignment in my project.Here in Header.ascx I add the following code:

<asp:Table ID="tblHeader" runat="server" Width="100%" CellPadding="0" CellSpacing="0">

<asp:TableRow>

<asp:TableCell  ForeColor="AliceBlue" Font-Size="Medium">

 <asp:Label ID="Label1" runat="server" ForeColor="White"></asp:Label>

    <asp:Literal ID="Literal1" runat="server" ></asp:Literal>

   

</asp:TableCell>

<asp:TableCell CssClass="UserInfo" ID="UserInfo" HorizontalAlign="Right"></asp:TableCell>

</asp:TableRow>

</asp:Table>

In Header.ascx.cs I add the following details:

  protected void Page_Load(object sender, EventArgs e)

        {

            if (!IsPostBack)

            {

                MySqlDataReader dr = objMasBLLogic.Header();

                dr.Read();

                if (dr.HasRows)

                {

                    StringBuilder address = new StringBuilder();

                    address.AppendLine(dr[0].ToString());

                    address.AppendLine(dr[1].ToString());

                    address.AppendLine(dr[2].ToString());

                    address.AppendLine(dr[3].ToString());

                    address.AppendLine(dr[4].ToString());

                    Literal1.Text = address.ToString();

                }

                StringBuilder strLoggedIn = new StringBuilder();

                strLoggedIn.AppendFormat("Logged in as: <span class='UserName'> {0} </span> ", Session["username"]);

                //strLoggedIn.AppendFormat("Logged in as: <span class='UserName'> {0} </span> | ", Session["username"]);

                //strLoggedIn.Append("<A href='mailto:[email protected]'>Contact</A> | ");

                System.Web.UI.WebControls.LinkButton SignOutLink = new System.Web.UI.WebControls.LinkButton();

                System.Web.UI.WebControls.HyperLink HelpLink = new System.Web.UI.WebControls.HyperLink();

                HelpLink.Text = "Help | ";

                HelpLink.ForeColor= Color.White;

                HelpLink.NavigateUrl = "EvHelp.htm";

                HelpLink.Target = "_blank";

                System.Web.UI.WebControls.HyperLink conlink = new System.Web.UI.WebControls.HyperLink();

                conlink.Text = "Contact";

                conlink.ForeColor = Color.White;

                conlink.NavigateUrl = "  mailto:[email protected]  ";

                conlink.Target = "_blank";

                Table HeaderTable = (Table)this.FindControl("tblHeader");

                TableCell UserInfoCell = (TableCell)HeaderTable.Rows[0].FindControl("UserInfo");

                UserInfoCell.Controls.Add(new LiteralControl(strLoggedIn.ToString()));

               // UserInfoCell.Controls.Add(HelpLink);

               // UserInfoCell.Controls.Add(conlink);

            }

        }

Here the problem is,when I run application the "Literal1" control works properly.But the stringbuilder "Logged in as" Can't be displayed properly.When I do action in particular page,the control "Logged in as:" not be displayed..Sometimes only displayed.How I display this all times in my application? Can any one help me to do this?
