Hello everybody, I'm working with asp.net and my project has login interface which accepts user's information and redirects to another page. After a user has logedout s/he never return to that page,but this doesn't happen,in contrast, when the user uses the back button s/he can again visit the page. I want to disable the back button, how can I? Or is there another method to do that? Thank you.

You can't. You are seeing the browser cached version of the page and any well written application will not allow to proceed using the secured page. Each page load should check the session existence and do necessary redirects.

Thank you all for your help.

You are welcome. You may also reconsider your websites navigation model. Something like Post/Redirect/Get[^].
Best wishes,
Navaneeth

You cannot. Perfectly. Although there are plenty of ways available through web of doing this.

Disabled Back Button is not a good idea.
And even if you check the Session object, still browser will load cached page as its not a postback.
you can use following property to expire the content on the client side. but still it will not be real-time.
Response.Expires
Response.ExpiresAbsolute
on the Logout page try setting Response.ExpiresAbsolute to the (DateTime.Now.AddSecond(5)) and see if that works.

function noBack()
{
window.history.forward();
}
noBack();
window.onload=noBack;
window.onpageshow=function(evt){if(evt.persisted)noBack();}
window.onunload=function(){void(0);}
this javascript may help you

People ask this all the time. It's a stupid request. The answer you were given, is easily defeated. Instead, tell us how your code is broken or poorly written so that you need to do this ( i.e. tell us why you want to do it, I am sure it will mean we can tell you how to fix your code ).

this coding is for deleting a record:
System.Data.SqlClient.SqlConnection connection = new System.Data.SqlClient.SqlConnection("Data Source=.\\SQLEXPRESS;AttachDbFilename=E:\\T\\DLI\\App_Data\\DLI_Database.mdf;Integrated Security=True;User Instance=True");
connection.Open();
System.Data.SqlClient.SqlCommand command = new System.Data.SqlClient.SqlCommand("DELETE FROM Items where Password ='"+ TextBox1.Text +"'", connection);
command.CommandType = CommandType.Text;
connection.Close();
Label1.Text = "Record deleted!";
HOW DO I DISABLE A RECORD INSTEAD OF DELETING IT SO IT CANT BE VISIBLE IN THE DATA GRIDVIEW.

Hi,
What is the difference between n-tier architecture and n-layered architecture.
What are the advantages of each one over the other.
How we will choose which one is going to apply.
Please help me out.

IS google broken where you live ?
Learn to code, and worry about these sort of things in their proper context. That is, if you don't know what the difference is, research both, then work out if there's any difference at all. There isn't.

I googled and found these [^]results.
And infact, the first one [^]looks to be the answer itself.
