Hello.

You're right, you need to get the KeyDown Event of the Textbox for this. I've implented such functions in an inherited DataGridView, so you could just call MyBase.OnKeyDown() from within the inherited DataGrid for this...

But back to your question:

Select Case e.KeyCode
      Case Keys.Down
            If Me.yourDtGrd.CurrentCell.RowIndex < Me.your.DtGrd.RowCount - 1 Then
                  Me.yourDtGrd.CurrentCell = Me.yourDtGrd(Me.yourDtGrd.CurrentCell.ColumnIndex, Me.yourDtGrd.CurrentCell.RowIndex + 1)
            End If
            e.Handled = True
      Case Keys.Up
            If Me.yourDtGrd.CurrentCell.RowIndex > 0 Then
                  Me.yourDtGrd.CurrentCell = Me.yourDtGrd(Me.yourDtGrd.CurrentCell.ColumnIndex, Me.yourDtGrd.CurrentCell.RowIndex - 1)
            End If
            e.Handled = True
End Select

Me.yourTextBox.Focus()
