Get value from another page

We are using an application that runs on asp.net and C#. When a user is logged in, their profile information is displayed (name, id number) on a Profile page (information comes from MSSQL). I would like to get the id number for the logged in user and pass that value to an embedded form (this part I know I can do), the struggle is figuring out how to get the id number from one page to the other page.

I am not proficient with C# or asp.net but I did find where the id value is at, I am not sure how to call it from my form page?

Pass Values Between ASP.NET Web Forms Pages

The following options are available even if the source page is in a different ASP.NET Web application from the target page, or if the source page is not an ASP.NET Web Forms page:

  • Use a query string

  • Get HTTP POST information from the source page

The following options are available only when the source and target pages are in the same ASP.NET Web application:

  • Use session state
  • Create public properties in the source page and access the property values in the target page
  • Get control information in the target page from controls in the source page

The main factor that should influence your approach should be the fact that this is a secure application and you do not want the information being passed to be prone to scrutiny.

First Option:

Use Cookies

On your firstPage.aspx

HttpCookie appCookie = new HttpCookie("IdValue");
appCookie.Value = "The value of your id here" or id.ToString();
appCookie.Expires = DateTime.Now.AddDays(1);
Response.Cookies.Add(appCookie);

To get:

SecondPage.aspx

HttpCookie aCookie = Request.Cookies["IdValue"];
String getValue = aCookie.Value.ToString();

Cookies expires depends on your Settings here appCookie.Expires = DateTime.Now.AddDays(1); it can be AddDays('MoreNumberofdays') like AddDays(4) it will expires in 4 days. Something like that.

some additional Guide

Second Option:

Class:

public class Class1
{
    public static string storevalue;
}

Page1.aspx

protected void Page_Load(object sender, EventArgs e)
{
            Class1.storevalue = "This is the value from page1";
            Response.Redirect("WebForm2.aspx");

}

Page2.aspx

 protected void Page_Load(object sender, EventArgs e)
        {
            string getvalue = Class1.storevalue;
        }
