HttpModule and User Controls

[Joey]

Hi,

i wish i could load up a UserControl from an HttpModule and render it to the
client without needing to go to an aspx page. don't know if this is
possible, i tried instantiating a user control and calling its RenderControl
method passing the Response.OutputStream as a parameter, but it doesn't do
anything.

i do not want to have fancy functionality like postbacks or anything once
the control is rendered. i just need this to display a list of error
messages contained in a dataset easily to the screen.

i know i probably should be using xslt to do this, since its just a display
issue, but using a user control with a datagrid control seemd such an easy
way of doing it...

i'm using ASP.NET 1.1 by the way..

A user control needs some sort of container. If you just want a simple
output without overhead implement a custom handler. Look for IHttpHandler
and ashx to get started.

Hi,

HTTP handler can itself dictate if it needs session or not, by implementing
IRequiresSessionState (read/write access) or IReadOnlySessionState (read
access) interfaces.

You can access session in PostAcquireRequestState
(context.PostAcquireRequestState +=new
EventHandler(context_PostAcquireRequestState))

If you need to store something prior to this event (like in BeginRequest),
you can store the object/data in Application (context.Application). In
PostAcquireRequestState, copy the object/data from Application to Session.
