This is what I am using and it doesnt seem to work. Am I missing something? UltraGrid is attached to a BindingSource.

Dim invRow As Infragistics.Win.UltraWinGrid.UltraGridRow = UltraGrid1.DisplayLayout.Bands(0).AddNew

invRow.Cells("Project").Value = "test"

invRow.Cells("TransNum").Value = "tran  num"
