If what you want to do is actually modify ASP.NET's generated control
html, you can do it like this:

Protected Overrides Sub Render(ByVal writer As HtmlTextWriter)
Dim sb As New System.Text.StringBuilder
dim html as string
Dim wr As New Web.UI.HtmlTextWriter(New IO.StringWriter(sb))
MyBase.Render(wr)
html=sb.tostring
' modify html here
writer.Write(html)
End Sub

This sub creates a stringbuilder, makes an HTMLTextWriter that writes to
the stringbuilder, then renders the base control into the stringbuilder.
Now we have the html text. Modify it as needed, then send it to the real
HTMLTextWriter.
