Hi! I have a form in my webpage. The scenario is to transfer a list (of strings)

C#

List<string> myLIst= new List<string>();

in the current page to another page when the form's submit button is clicked and the user is redirected to that other page. How can this be done?

Hi,

you can send data to other controls via the constructor.

C#

public List<string> myStringList;

//the construtor of you "otherpage"
public MyPage(List<string> sendedStringList)
{
    myStringList = sendedStringList;
}

Best regards...

Use Session State: http://msdn.microsoft.com/en-us/library/ms178581(v=vs.100).aspx[^]

Yep fully agree with you, Session state is one of the most suitable solution for it. My five to U.

Thanks a lot for the help. And what about a user-defined class? I tried to do this:
public class Person
{
public string FirstName{ get; set; }
public string LastName{ get; set; }
public Person(string strFirst, string strLast)
{
FirstName = strFirst;
LastName = strLast;
}
}
I put this in source page:
Person p1 = new Person("first", "last");
Session["p1"] = p1;
And in target page:
Person ps = (Person)(Session["p1"]);
<p>@ps.FirstName</p>
Now I get System.NullReferenceException. Its not working.

Without seeing the entire project i can only speculate that your issue is regarding when you pull your person object out of the session state.

The easiest way to get around that is to create a readonlt property that gets the Person object from the session and use that to access your object.
i.e.

public Person MyPerson {
get { return (Session["p1"] != null ? (Person)Session["Person"] : new Person("","")); }
}

Then in your page you can just access it like this <p><%=MyPerson.FirstName %></p>
