Hi,

I am trying to use dynamic rad-menu in our application. I am following the code mentioned in telerik.com mentioned in the link below:
http://www.telerik.com/help/aspnet-ajax/panelbar-dynamically-created-radmenu.html
The problem is that the submenu side is not expanding instead it is showing at the rightmost part of parent nodes.
For reference I post my code below.
.aspx
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="mymenu3.aspx.cs" Inherits="Presentationlayer_mymenu3" %>
<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

            DataTable dt = new DataTable();
            dt = links.Tables[0];
            RadPanelItem panelItem = (RadPanelItem)RadPanelBar1.FindItemByValue("templateHolder");
            RadMenu myMenu = new RadMenu();
            myMenu.Width = Unit.Percentage(100);

            myMenu.DataSource = dt;
            myMenu.DataBind();
            panelItem.Controls.Add(myMenu);

            foreach (RadMenuItem myItems in myMenu.GetAllItems())

}

            </telerik:RadPanelItem>
        </Items>
        <CollapseAnimation Duration="100" Type="None" />
        <ExpandAnimation Duration="100" Type="None" />
    </telerik:RadPanelBar>
protected void Page_Load(object sender, System.EventArgs e)
   {
       DataTable dt = new DataTable();
       dt.Columns.Add("ParentId", typeof(int));
       dt.Columns.Add("CategoryId", typeof(int));
       dt.Columns.Add("Title", typeof(string));
 
       dt.Rows.Add(null,1,"1");
       dt.Rows.Add(null,2,"2");
       dt.Rows.Add(1,3,"3");
       dt.Rows.Add(1,4,"4");
       dt.Rows.Add(2,5,"5");
       dt.Rows.Add(3, 6, "6");
 
       RadPanelItem panelItem = (RadPanelItem)RadPanelBar1.FindItemByValue("templateHolder");
       RadMenu myMenu = new RadMenu();
        
       myMenu.Flow = ItemFlow.Vertical;
       myMenu.DataTextField = "Title";
       myMenu.DataFieldID = "CategoryId";
