Hi,
try this 
lbl1.Text = lbl1.Text+ "<br />"

    Public Shared Function BrakeRow(ByVal _count As Integer) As LiteralControl
        Dim tmp As String = ""
        Dim i As Integer
        For i = 0 To _count - 1
            tmp += "<br/>"
        Next
        Return New LiteralControl(tmp)
    End Function


    Public Shared Function non_breaking_space(ByVal _count As Integer) As LiteralControl
        Dim tmp As String = ""
        Dim i As Integer
        For i = 0 To _count - 1
            tmp += " "
        Next
        Return New LiteralControl(tmp)
    End Function
