Unable to get a Profile custom (object) collection to bind to Gri.

[a]

Q. Unable to get a Profile custom (object) collection to bind to
GridView,etc (IList objects)?

This is my first custom object so I may be doing something rather simple,
wrong, or it may be something else to do with the Profile object. Either
way, I need help

Here's a brief description of the
code----------------------------------------------------------------------------------

1) I have a custom object: "School.Teachers" (see below)

2) which is used as a Profile object data type in the web.config file:

<profile defaultProvider="AspNetSqlProfileProvider" >
<properties>
<add name="Teachers"
type="School.Teachers"
allowAnonymous="true"/>
</properties>
</profile>
3) I'm setting the value of a Profile object (ASP.NET 2.0) equal to the
custom object:

School.Teachers tlTeachers = new School.Teachers();
tlTeachers.Add(new School.Teacher("Buck"));
Profile.Teachers = tlTeachers;
4) Code like this works:

Label1.Text = Profile.Teachers.Count.ToString(); // The number of items in
the profile object

Label1.Text = Profile.Teachers[1].FirstName.ToString(); // The value of an
item at a particular index position
5) But this does not:

GridView1.DataSource = Profile["Teachers"]; // Populate the GridView1 from
the Profile Object
GridView1.DataBind();
The custom object:
"School.Teachers"---------------------------------------------

public void Insert(int index, Teacher value)

List.Insert(index, value);

List.Remove(value);
