DataGridView, BindingList : Add and Remove

[Claude]

It is possible to capture the "AddingNew" event to create our own object
before it is append to the BindingList (using e.NewObject = new ...)

When the user press delete on a row to remove a row from the DataGridView, I
need to do some stuff before it actualy modify the content of the
BindingList. Is it possible ? I tried to capture "List_Changed" event, but
it's too late, the object is already gone from the bindinglist !

What can I do ?

Thanks,
Claude

In this case, you can inherit from BindingList<T> and override the
RemoteItem method. You might also wish to consider SetItem (which is used by
the indexer "set").

class MyList<T> : BindingList<T>
{
protected override void RemoveItem(int index)
{
// do something fun and interesting to this[index]
base.RemoveItem(index);
}
}
