   private void AcceptOrReject(DataRow row)
   {
       // Use a function to validate the row's values.
       // If the function returns true, end the edit;
       // otherwise cancel it.
       if(ValidateRow(row))
           row.EndEdit();
       else
           row.CancelEdit();
   }

   private bool ValidateRow(DataRow thisRow)
   {
       bool isValid = true; 
       // Insert code to validate the row values. 
       // Set the isValid variable.
       return isValid;
   }
 Private Sub AcceptOrReject(ByVal row As DataRow)
    ' Use a function to validate the row's values.
    ' If the function returns true, end the edit; 
    ' otherwise cancel it.
    If ValidateRow(row) Then
       row.EndEdit()
    Else
       row.CancelEdit()
    End If
End Sub
 
Private Function ValidateRow(ByVal row As DataRow) As Boolean
    Dim isValid As Boolean
    ' Insert code to validate the row values.
