When implemented in a derived class, this method indicates whether the specified value can be removed from the collection. By default, this method always returns true.
This method is called when the user tries to remove an item that is an original member of the collection. This method is not called when removing items that were added in the current editing session because they are not yet part of the collection.
- Full trust for the immediate caller. This member cannot be used by partially trusted code. For more information, see Using Libraries from Partially Trusted Code.
