I need to render a user control as a HTML string. I do not want the control 
to appear on the page, however.  Here is what I am doing…
I have an HTML template that will ultimately be sent via e-mail. Inside the 
template I have IDs setup for each section that will be replaced with dynamic 
data.  In one section I need to display a specific kind of data. I already 
have a user control that generates what I need. I need to get that control to 
fire and then get rendered as HTML to be placed in the appropriate section of 
the fore mentioned HTML template. This is the code I have so far:

Private Function BuildPropertyDetialsInfo() As String
Dim propertyInfoControl As New StringBuilder
      Dim propertyInfoUserControl As New UserControl
      Dim propertyInfoStringWriter As New StringWriter(propertyInfoControl)
      Dim propertyInfoHTMLWriter As New 
HtmlTextWriter(propertyInfoStringWriter)

      Try
        propertyInfoUserControl.LoadControl(propertyDetialsInfoPath)         
       
        propertyInfoUserControl.RenderControl(propertyInfoHTMLWriter)
      Catch ex As Exception
      End Try
      Return propertyInfoControl.ToString
End Function
I donl’t get anything back. I am assuming that I need to add the control to 
the collection, but I don’t know how I would do this since I am not working 
on a web form. I am inside a class that doens’t have access to a form page. 
Any thoughts?
