I have created two custom field properties on a BO and set this BO to my BusinessBindingSource BO.  I set the DataSource for my grid to the BindingSource and two of the column's FieldName properties are set to my custom fields.  These fields are not showing up in the grid, but all other properties are.  The custom properties show as blanks.  Is there something else I need to do?

Did you override the GetCustomBindablePropertyDescriptors() method within the business object?
