Nothing ??

and another problem. When I arrive at the last cell and he will not grasp ENTER to the next control. He stops at the last Cell.

The situation is as follows...
In event KeyDown of my grid i put a code:

If e.KeyCode = Keys.Up Then
            appGrid.PerformAction(Infragistics.Win.UltraWinGrid.UltraGridAction.AboveCell)
ElseIf e.KeyCode = Keys.Down Then
            appGrid.PerformAction(Infragistics.Win.UltraWinGrid.UltraGridAction.BelowCell)
End If

that happens when I press the up and down it goes into edit mode selects the most content of the ballot.
And I need to get the contents of the note is selected.

Excuse my English, I am Brazilian and I'm using google translator.
