Gridview, bind column to property of nested type

[Ron Young]

Given the following:

Class UserRole
{
Public string RoleName { get; set; }
Public string Description{ get; set; }

Public override string ToString(){ return RoleName; }
}

Class MyUser
{
Public UserRole Role{ get; set; }
Public string FirstName{ get; set; }
}

I want to bind a list of MyUser to a gridview, and one of the columns in the gridview should display the RoleName of the user.

I thought overriding ToString() in UserRole would do the trick but I get a NullReferenceException.

I know my code to generate a List<MyUser> is correct.

Here's the bound field for that role column in the gridview:
