Good morning,
I have a bindinglist of my custom objects and need to check, before
adding items, if an item exists in list and then cancel inserting.
I have tried to create an object that inherits from
bindinglist<mycustomobjectbut I cannot override Add method.
This because this bindinglist is a datasource for a datagrid and need to
avoid to insert duplicated instances.
Thanks.
Stefano.
