UltraGrid Causing Bindingsource OffEnd to fire until all rec

I am using an UltraGrid to display data from our database. We batch data as there may be many many records in the table. We have added logic to the InitializeLayout of the UltraGrid to create an appearance, set the backcolor of the appearance to red and then add the appearance to the appearances collection. We then added logic to the InitializeRow of the UltraGrid to check the value of a cell and set the Appearance of the cell based on the cell value. What we are running into is the GetCellValue is causing the bindingsource's offend event to fire until all records have been retrieved from the database. As a test if I remove the GetCellValue line and just set the appearance for all rows everything works as expected (batching). Has anyone seen this?
