Why can¡¯t I use an aspx page class as TypeName for ObjectDataSource?

Y

Hello,



I'm creating asp.net 2.0 web site app, I tried to use ¡°ObjectIssue.Page1¡±
as TypeName of ObjectDataSource, received error message ¡°The type specified
in the TypeName property of ObjectDataSource 'object1' could not be found.¡±,
If I instead use a class in App_Code folder as TypeName, it works find. But
I can¡¯t figure out why it didn¡¯t work for aspx page class?



Here¡¯s the code:



--------- Page1.aspx.cs: ----------



namespace ObjectIssue

{

public partial class Page1 : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

}



public List<Person> GetPerson()

{

List<Person> pList = new List<Person>();

pList.Add(new Person("James", 27));



return pList;

}

}



public class Person

{

public Person(string sName, int iAge)

{

_name = sName;

_age = iAge;

}



private string _name;

public string Name

{

get { return _name; }

set { _name = value; }

}



private int _age;

public int Age

{

get { return _age; }

set { _age = value; }

}

}

}
