Hi guys,
I'm trying to find information on adding post-cache substitution-awareness
to a custom control. Almost every page I find on this is simply repeating
the www.asp.net's examples, stating that this is possible, as the AdRotator
is a "post-cache substitution-aware" control. But no farther explanation is
given. The only example shows how cool it is to change a label's text in an
OutputCached page. I'm looking for some more advanced information on the
subject.
What I really want to do is use Paging and Sorting (and callbacks) on a
GridView on a page that uses OutputCache. Currently, with OutputCache turned
on the GridView will only sort one time before it becomes completely static.
Will post-cache substitution work for data that is not a string?
Could someone point me in the right direction on how add this functionality
to a custom control, say one that inherits from GridView or other controls
that use callbacks?
Thanks,
David
