c# - config change not reflected -

i have few hyperlinks values assigned in code behind. assignment happens in page_init event.

but values picked web.config.

i changed values in web.config not being reflected in hyperlink.

i have done app pool recycle, iis reset , cleared temporary asp.net files.

need suggestions resolve this.

edit: posting code requested:

this.hyperlink1.navigateurl = system.configuration.configurationmanager.appsettings["footer.link1.url"];

this done in method silentlogin_prerender in turn called in oninit event

this.prerender += new system.eventhandler(this.silentlogin_prerender);
