hi Kevin,

i tried subclassing UltraGrid of Infragistics with mmDataGrid studying the code in mmDataGrid.cs but got this error upon building the solution.

C:\unzipped\ultrawingrid_v3002003316\_ultrawingrid_v3002003316\UltraGrid.cs(85): 'Infragistics.Win.UltraWinGrid.UltraGrid' does not implement interface member 'OakLeaf.MM.Main.ImmBindingBase.BindingSource'

any suggestion on how i should proceed? thanks.

Bobby
