Dear all;

I have the following code below and I have been spending time trying to debug it but I can't understand why I am getting the illegal character error message. See my code below. Thank you.

workheader.master.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Xml.Linq;
using System.Xml;

public partial class workheader : System.Web.UI.MasterPage
{
    protected void Page_Load(object sender, EventArgs e)
    {
        load();
    }

    protected void load()
    {
        
       
       XDocument doc = XDocument.Load(Server.MapPath("App_Data/XMLFile.xml"));

        foreach (XElement menuItem in doc.Elements("MainMenu").Elements("MenuItem"))
        {
            string a = menuItem.Element("LinkURL").Value;
            string b = menuItem.Element("LinkLabel").Value;


            hp.Text = b;
            hp.NavigateUrl = a;

            if (doc.Elements("submenu") != null)
            {
                foreach (XElement subItem in doc.Elements("MainMenu").Elements("MenuItem").Elements("SubMenu").Elements("SubMenuItem"))
                {
                    string c = subItem.Element("LinkURL").Value;
                }
            }

        }


    }

}

Xml preserve the whitespaces so you need to use Trim() to remove blanks from the both side of the string value.

hp.Text = b.Trim();
 hp.NavigateUrl = a.Trim();

Ok, that fix the illegal error problem, however though the code is currently not doing much unfortunately, it doesnt show the associated submenu when the main menu is clicked on unfortunately.
