How to programatically load control in HTTPHandler ?

[Alex Nitulescu]

Hi. I have a web.config which says that all files with the "axd" extension
should by a special handler.

The handler writes some stats to the "axd" page.

Public Class WhosOnHandler
Implements IHttpHandler
Public Sub ProcessRequest( ByVal context As System.Web.Http Context)
Implements System.Web.IHtt pHandler.Proces sRequest
............
context.Respons e.Write("<table border=1 cellpadding=4 bgcolor=orange> ")
context.Respons e.Write("<tr><t d colspan=4 align=center>")
...........
Public ReadOnly Property IsReusable() As Boolean Implements
System.Web.IHtt pHandler.IsReus able
Get
Return True
End Get
End Property
End Class

Note that there *is no* axd aspx page in my project ! Whenever a user
presses on a button named "Stats", the code executes
Response.Redire ct("TestForm2.a spx") and the handler detects a call to an AXD
file and takes care of the rest, as above.

My problem is that this axd file looks pretty plain, only with
"context.Respon se.Write". I have some custom controls which I would like to
load to make this page look consistent with the other pages on this website.

So the question is: how do I programatically load my controls in this
situation? I only have the 'Context' object and I need to somehow get to the
'Page' object to be able to say Page.Controls.A dd. In other words, how do I
obtain an instance of this page ?

Thank you.
Alex

If you want Page, then just use ordinary .aspx. I think the http
handler is completely useless since its URL has to end with the ext
".axd", and you could just replace it with a Page with diffenrent
content-type.

It's not easy to load a Page by yourself, because there are many issues
that ASP.NET has to deal with, such as event dispatching, postback, etc.

Alex,

You can take a look at PageParser.GetC ompiledPageInst ance which takes the path to the aspx you need to load and return an IHTTPhandler. Call ProcessRequest to execute the aspx page.
