I have a question about binding an UltraGrid to custom data objects.  We have a large number of business data objects that all derive from a base data object.  Whenever we add a new property to the base data object it immediately shows up as a visible column in dozens of grids across the application.  We then have to open each grid in designer mode and explicitly hide the column.  We are looking for a way to set the default grid behavior so that new columns in the datasource will be ignored unless we make the column visible.  Can you recommend a way to make this happen?  Thanks.
