Hi,

I have a BindingList<T> collection and I am adding concrete object T in to
the binding list. Before adding them, I want to verify if object with same
data exist in the collection. When I use Binding list’s Contain method to
check if object exist in the collection, it always returns false. Is there a
way to achieve this? I have tried implementing IComparable interface on my
concrete class, but getting same result.

Code sample:

BindingList<User> uBL=new BindingList<User>();

User u=new User();
u.FirstName=”TTT”;
u.LastName=”CCC”;
if (! uBL.Contains(u)) //this always returns false
{
    uBL.Add(u)
}

Public class User{

Public string FirstName=string.empty;
Public string LastName=string.empty;
Public User(){}

}

Thanks
Hiten
