I have a grid bound to a Business Object, I am using a GetEntityList<> call to get the data.

This all works fine, but in the grid I need to add a column with a calculated value (from data in the entity).

What's my best approach here? Should I manipulate the dataGrid manually, or should I add the calculated value into the entity object.

It's not 100% clear to me yet whether the grid is binding to the actual entity list, or drilling in a bit and binding to a dataset behind the scenes.
