Type: SystemObject

The value to remove.

Return Value

Type: SystemBoolean
true if it is permissible to remove this value from the collection; otherwise, false. The default implementation always returns true.

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.
