Hi

I am retrieving the following error when I bind a custom collection with a gridview
"System.Reflection.TargetException: Object does not match target type."

Some details.

The base class is

public class SortableBindingList<T> :BindingList<T>, ITypedList
{
       .....
}  

The collection class is

public class MyCollection : SortableBindingList<MyInterface>
{
       .....
}

 The collection contains two types of objects that inherit from the same interface

Thanks

Itzik
