But do not want to let it appear new line, this problem a lot of netizens asked, in fact, to achieve a very simple, but we did not think just. The following is illustrated by a simple example

DTNEW.COLUMNS.ADD ("Time", GetType (String))
DTNEW.COLUMNS.ADD ("Cost", GetType (String))
Dim Intcircle as Integer
For intcircle = 0 to 3
Dim Dtrow as DataRow

            dtrow = Dtnew.newrow
             dtrow (0) = Watts + intcircle
             Dtrow (1) = 3500 + * Intcircle
             dtNew.Rows.Add (dtrow)
        Next
         Dim Dtview as New DataView
        Dtview = Dtnew.defaultview
        dtview.allownew = false                ' Eliminate new lines
         Dtview.allowdelete = false         ' does not allow users to delete rows via the DELETE key on the keyboard
