Default How to avoid reloading of navigation menu every ti

Hi,

 I am using a database driven menu for navigating to different pages. Is there a way to avoid reloading of the menu every time a page is called. I tried different method but all of them makes call to database everytime

My first try was as a usercontrol. Inside the usercontrol I had the menu. I had the menu databind inside a !(IsPostBack) condition, but still it kept binding itself. I tried binding it on onnit event too. My second attempt was on masterpages. I had the menu in masterpage and it kept binding the menu everytime a page is requested or a post back is made.The third try was using an interface which I extended like this on the partial class definition

public partial class Order_Query_Report : System.Web.UI.Page, CustomParent.IPageToIncludeHeaderFooter

The header was coming through that interface which internally contains a usercontrol (which in turn contains the menu).

None of them helped me to achieve what I was looking for.



Another approach was to have two iframes and having header on top and content on bottom. I had the menu fire javascripts in order to load the pages on bottom iframe. But it had significant drawbacks. The URL on top of browser is always constant (the url of header). Secondly, there were lots of issues in terms of authentication, disconnected communication etc.



It will be great if someone can advice me how to achieve a header menu which doesn't rebind everytime.

I tried ajax , but that also didn't help.Every time there' s a redirect, the menu binds itself

I don't see how it's possible for the menu to bind to it's data source when you placed the DataBind() method call inside of an If Not IsPostBack conditional.

That probably means it is binding somewhere else. Is it hooked to a SiteMapDataSource control? If so I think that will automatically bind every time unless you employ caching.
