Data Deletion Using the ObjectDataSource Control

[ME]

I can't seem to delete records using an objectdatasource. The object is a
Typed Collection built by Visual Studio that access a SQL Database. When I
try to delete using the ObjectDataSource it displays a message that says:

Value cannot be null.
Parameter name: Original_Description

This URL is supposed to be a documented titled "Data Deletion Using the
ObjectDataSource Control" but it doesn't seem to work (as of posting).
