Providing a delayed autofill/validation for a DataTable

Good afternoon,
I want to provide some autofilling functionality for a Windows Forms application I am writing, in particular, filling address fields based on an entered Zip code. The data is all stored in a typed DataSet, which is returned from a data layer object. I can do the autofilling from the UI, but this data object is used in a number of different places, for a number of different applications. So, I want to hook up all the business logic (autofill, validation, etc) to the DataTable, with the validation done on a different thread. The ColumnChanging and RowChanging events work perfectly, and I create a new System.Threading.Timer to handle the delay so that validation after a 100ms pause after the last update.
The problem that I am having is that when I change values in the DataTable for the autofilling/validation, the updates don't always show up in the UI. The UI is binding to the DataTable using a BindingSource. Is there some way I can force an update from the DataTable? Or is this a problem with multiple threads making changes to the DataSet?
