Hi guys

 I have weird situation that i have a home page with two hyperlinks that pass querystring to call a masterpage/contentpage site.

the masterpage has a menu and contentplaceholder. the content site fills the contents using the database. The querystring from the homepage is uses to determine which menu to display (dynamically generated)

the problem i having that when i enter the first site (siteID = 1) the corrent menu is displayed, but then go back on the browser to even manually update the url to siteID = 2, the old menu remains persistant, its doesnt refresh to the new site ID. on masterpage load event i have session(siteID) = request.querystring(siteID). using debug i have made sute teh session site is is the correct one.

can you please tell what must be happening to not make the menu refresh looking at the new site ID. the query out put is correct as well.

I believe that if a webpage has QueryString it does not store that page in history without it. So history shouldn't load the same page as cached unless it has the same querystrings... but here is how cache for the page can cleared right away:

Response.Cache.SetAllowResponseInBrowserHistory(false);

Hi,

Base on your description, you generate the menu from database, and you want to re-generate the menu according to the url param, right?

Do you add this code?  this.menu.DataBind()

You need to rebind the menu control when you change its datasource.

Hope it helps.

yes i have got the databind once i attach the datasource, but still no result. bit more details on my situation
