Passing C# custom objects in Session between asp.net web pages

I have a frustrating issue when trying to pass a custom object from 1 page of a web site to another. When I try to use the object from session on the page 2 it is null. I believe that my syntax is correct as when I take the code out of my larger solution and run it on it's own it works fine.

I am wondering if there are any settings in visual studio, aspx files, project properties that may be set on my project that may be causing this session object not to work?

Simplied syntax that I am using is; on page1

Person p = new Person;
p.name = "john"; 
p.secondName = "doe";
Session["person"] = p.
Response.Redirect("Page2.aspx")

Page 2 on page load method

Person p = (person)Session["person"]
textbox1.Text = p.name;
textbox2.Text = p.Secondname;

As I said this code works fine on it's own but not as part of my larger works project. Any ideas on why this may not be working would be greatly appreciated

There are three possible options.

First one is that inside your larger project session state is disabled. Please visit Turn Off ASP Session State in Active Server Pages and IIS for more details.

Second option would be that exception occurs somewhere inside your application (separate thread) resulting in application restart and session state loose. You can check this by hooking to Application error inside Global.asax like this:

    void Application_Error(object sender, EventArgs e)
    {
        Exception ex = Server.GetLastError();
    }

The last option would be that session["person"] value is changed in other module or page.

See as per your code if there is database connected then i suggest you to do whatever you want to on page1 and save it to db in single or multiple tables, depending upon the requirements. Now paas the id to page2 as querystring. Format looks like

Response.Redirect("~/page2.aspx?id=67"); where is the dynamic unique id from database. Now on page 2.aspx query on the id you have passed.

Try code with,

Response.Redirect("Page2.aspx", false);
