Hi CS,
From your description, you have some ASP.NET controls that will be added
into page dynamically. Also, you currently cache these control instances in
ASP.NET cache, however, you encounter some problems when any of those
controls try registering some client script on page, correct?
Based on the error message you mentioned, the ASP.NET runtime indicate that
the script registering code has been done after page's "PreRender" stage.
For the control elements, are they your custom controls? If so, would you
show me the script registering code in those controls? Since you add those
controls in page's PreRender event(the last event we can do persistent
changes to ASP.NET page), it is possible that any other changes in your
custom controls is invoked too late.
For dynamic controls, it is recommended to be created in page's Init or
Load event so that the dynamic loaded control can also go through those
page events (such as postback event processing, ....) correctly.

Subject: How to avoid that something be saved in cache
Date: Fri, 23 May 2008 11:05:15 +0200
>Hello,
I have a dictionary made with objects which contain a control element, the
control element is added to a Page when I want to edit the dictionary
content.
I put this dictionary in cache to improve ovaral speed.
But I am using Ajax.Net and somme of my controls are registering script
with
>the scrip manager on the PreRender stage of the control and it appears
that
>the control elements, when saving the dictionary in cache, are also saved
as members of the main dictionary object.
Doing so, depending on their status at the time of caching, they seem to
save an indicator saying that Prerender as aleady been done and when I
reload from cache and try to display again theses controls, they are
unable
>to register their script because the indicator says that:
Script controls may not be registered after PreRender.
So I am looking for a fast way to avoid thta the control element in each
object e saved in cache ?
Isn't their some declarative syntaxe to set on the element and saying
'Don't
>go in cache'
Thanks for help.
CS
