Hi all,

I am just about to re-write our web portal (200+ aspx pages) from the ground up, the technologies I am going to use are VS 2010, SQL 2008, ASP.NET AJAX (latest version might consider the beta!), IIS7. I am going to use master pages, user controls within the pages, a lot of the pages are going to have tabstrips, grids, treeviews, panels, and I want to use AJAX for the best performance. My first question is what do you think is the best way to use AJAX, e.g. Manager on the master page and proxies on the content pages, or just a manager on the content, I have nothing on the master page that needs AJAXing, that is all on the content pages. The next question is the use of user controls within an AJAX environment, again is it better to lots of user controls each attempting to do their own bit of AJAX with their own AJAX manager or again just use the proxies. Is it better (from a performance perspective) to not use user controls and attempt to get everything written directly into the content pages rather than lots of user controls.

A typical layout is going to be

Master page,
    Content page,
        Tabstrip,
            Usercontrol
            Usercontrol
            Usercontrol

or

Master page,
    Content page,
        Treeview,
            Usercontrol
            Usercontrol

any advice is welcomed.

Thanks

Alex

Hi Alex,

The correct way to use Telerik's Ajax controls is to place a RadAjaxManager in the MasterPage (or main ASPX page) and RadAjaxManagerProxy controls in the content pages (or user controls) where needed. This is because only one RadAjaxManager instance can exist at a time.

As for your second question - this is a rather general ASP.NET performance question. In my opinion, it is more important how many controls you have on a page and the loaded user controls, rather than how many user controls you have.
