Hi,

I'm having some trouble with views that have usercontrols on them, basically it seems the controls are getting rendered before the handler is executed so any data being passed via HttpContext.Current.Items for example doesn't always get seen by the view ... however subsequent requests do then work, but it's as if it's caching or maybe has managed to execute quicker.

I've tried quite a few different ways to workaround this now like using App/Session vars but it doesn't help. From looking at the source it seem's dependant on the order it's currently executed in so I've been trying to modify it to return a custom Page class with an extra event that is run once the handler is executed and thus giving a point later in the request for the control to bind too, but so far my event doesn't seem to be firing in time.

Are you able to shed any light on this or recommend proper use of controls on views?

Kind Regards
Jamie

I can try and put something together if you need it, it's fairly simple to recreate though basically ...

We have views that will put a control on the page like so ....

<%=Xhtml.RenderUserControl("~/Controls/WebList.ascx", new { Resource = Resource }) %>

The controls load event will then generate a table based on some meta data passed via Http.Items and the resource. However the Items come through as null on the first request because the handler hasn't run / completed. I have also just discovered putting a simple sleep delay in the control load event before it does it's thing also seems to solve the problem (but that isn't a good fix!)

Let me know if you still need a sample and I will have to make a separate project for you.

Just to let you know this was resolved, the issue was caused by a delay in our controls and their id's being set during initialisation.
