@ OutputCache in usercontrol problem
Hi to All,
I am using <% @ OutputCache Duration="60"
VaryByParam="none" %> in my
usercontrol say "myControl.ascx". This user control has a
property say
"title".
Now am Dynamically Loading this control in "myPage.aspx"
like this
Control ctl = LoadControl("myControl.ascx").
and then performing casting operation in order to set the
property value
((myControl)ctl).title = "Welcome to my Site"
But when i run the page it gives me following error
System.InvalidCastException. Specified cast is not valid.
And the beauty of this problem is that when i remove the
line <% @
OutputCache Duration="60" VaryByParam="none" %> The page
successfully
executes.
Please suggest.
Thanx in advance
Marshal

Rory #2 @ OutputCache in usercontrol problem
make sure that the header information for your control
file contains a class name
eg <%Control ClassName="myControl"%>
for further info on loading controls dynamically:
[url]http://msdn.microsoft.com/library/default.asp?[/url]
url=/library/en-
us/cpguide/html/cpconinstantiatingusercontrolsprogrammatica
lly.asp
also note: if the user control supports caching, the
object returned from this method is not actually a
UserControl, but a PartialCachingControl.
