Blogging about SharePoint

I've just posted a question on the MSDN forums as follows:

I have a Task list that has two content types that inherit from Workflow Task.  Let's call them CT1 and CT2.  CT2 has a Business Data Column while the others do not.  This Task list can contain several thousand records, though the number of active tasks at any given time is small (e.g. 20).  The Business Data Column gets its data from a web service.  I have a view that displays only the active tasks, and includes the business data column in the columns displayed.  When I click on the update link (the circular green arrows at the top of the business data column), the subsequent pages warns that it will update ALL items in the list, not just the ones in the current view.  Is it possible to restrict the update to only the items in the view?

I posted that at http://social.msdn.microsoft.com/Forums/en-US/sharepointbdc/thread/fae084a3-0fdf-4951-a8f9-d0229a4b0a83 .

In my scenario, updating only a few records is perfectly reasonable, and the time that it would take to update all records would be enough to make the users unhappy.  In my scenario, a user might want to run the update several times a day, and really only cares about making sure they have the latest data for a very small number of rows.  I'd like to be able to offer the users a way to update only a single record at a time, or only the records in their view. 

If you have any suggestions, please post a comment here, on Twitter, or in the MSDN forum.
