Sorry

I removed the ampérsand and now is working fine

Thanks

I used

For Each M In FICHAS_MUTUALESUltraGrid.KeyActionMappings
If M.KeyCode = Keys.Enter & M.ActionCode = Infragistics.Win.UltraWinGrid.UltraGridAction.CommitRow Then
FICHAS_MUTUALESUltraGrid.KeyActionMappings.Remove(M)

End If
Next
but didnt work

What you probably have to do here is remove the KeyActionMapping from the grid's KeyActionMappings collection that is handling the enter key.

 for (int i = this.ultraGrid1.KeyActionMappings.Count-1; i >= 0; i--)
            {
                GridKeyActionMapping gridMapping = this.ultraGrid1.KeyActionMappings[i];
                if (gridMapping.ActionCode == UltraGridAction.CommitRow
                    && gridMapping.KeyCode == Keys.Enter
                    && (gridMapping.StateRequired & UltraGridState.AddRow) == UltraGridState.AddRow)
                {
                    this.ultraGrid1.KeyActionMappings.Remove(gridMapping);
                }
            }

Hi,

That doesn't really answer the question. I need to know if the row is fixed or not. What setting are you using for AllowAddNew?

i'm using addrow at the bottom
