LINQ to XML って HTML の Render に使うといい感じ？

Public Class HelloButton

    Inherits System.Web.UI.Control
    Private _alertMessage As String

    Public Property AlertMessage() As String

        Get

            Return _alertMessage

        End Get

        Set(ByVal value As String)

            _alertMessage = value

        End Set

    End Property
    Private _text As String

    Public Property Text() As String

        Get

            Return _text

        End Get

        Set(ByVal value As String)

            _text = value

        End Set

    End Property
    Protected Overrides Sub Render(ByVal writer As System.Web.UI.HtmlTextWriter)

        Dim html = <input type="button" id=<%= Me.ID %>

                       value=<%= _text %>

                       onclick=<%= "alert(""" & _alertMessage & """)" %>/>

        writer.Write(html)

    End Sub

End Class
