yup.....
its doing well

I have already checked it, no effect.

I'm not getting any error. when this page(Profile.aspx) is loaded, all the user's info is non-editable. Edit button make them editable. let i changed the UserName and email and Click on SaveChanges button. In debug mode i saw that text boxes of this page in "btn_profileSaveChanges_Click" never show/have the data which i write in editing mode in these textBoxes. these textBoxes always show the data which is auto-populated on pageLoad.
second thing is the "db.SaveChanges()" is built-in function. it is just used to save any change in database like "SubmitChanges()".

Thanks for your time :)

Hmmmmmmmm
ok i will. Thanks :)

actually i am reading all the nodes(A, B, C.........) from text file as string and edges between them as integer. In BFS function,at the end, i am doing "e.add(a)" which is giving me error that change the type of "a" as node and when i do it it creates error in my add() function because it takes string. i dont now what to do it :(

ok thanks a lot :)

sorry that session code i just try and forgot to remove it. my actual code is without session line. but by including that line i'm getting nothing. i dont know whether i use that session code correct or not because i am using it first time.
can you please guide me if you feel easy?

I could not understand this. Here is my login page code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace Project_sn
{
public partial class Default : System.Web.UI.Page
{
SocialNetwork_DBEntities sn_DBEntities = new SocialNetwork_DBEntities();
web_users user = new web_users();
public void add_user(object sender, EventArgs e)
{
try
{

user.Firstname = tbox_firstName.Text;
user.Lastname = tbox_lastName.Text;
user.Email = tbox_email.Text;
user.DOB = Convert.ToDateTime(tbox_DOB.Text);
if (Radio_male.Checked == true)
{
user.Gender = "Male";
}
else
{
user.Gender = "Female";
}
user.Username = tbox_userName.Text;
user.Password = tbox_password.Text;
user.Biography = tbox_biography.Text;

sn_DBEntities.web_users.Add(user);
sn_DBEntities.SaveChanges();

lbl_conformRegister.Visible = true;
}

catch (Exception)
{
Console.WriteLine("an error occured!");
}

}
public void btn_login_Click(object sender, EventArgs e)
{

var userInfo = sn_DBEntities.web_users.Where(u=> u.Username == tbox_loginUserName.Text && u.Password == tbox_loginPassword.Text).FirstOrDefault();

if (userInfo != null)
{
Session["Email"] = tbox_email.Text;
Response.Redirect("ProfilePage.aspx", false);
}
else
{
lbl_loginError.Visible = true;
}

}

protected void Page_Load(object sender, EventArgs e)
