need help in master pages using ajax

hi all i need an advice concerning the use of master page using async

first ive discovered that page loads using links to pages of the same master page cant be done without postback so am searching for a way to apply a way of implementing my site using master pages and ajax

so i put a master page with a header and a contant place holder next i implemented a page using mymaster page and i put within a iframe for the other pages so as those pages can be loaded asyc for the first time it seemd working just fine but when i put in the pages residing in the iframe an ajax implementation it asks for script manager so heres the prob

plz give me a good way implementing my master page without many postbacks and without using multiview

a conceptual way ........ thanks a lot

Why use masterpages if you want your pages to behave like you are using frames? You would probably be better off if you just had an aspx page with an iFrame.

Need Microsoft.Web.Extensions.Design.dll

When installing the Ajax Control Toolkit 2.0 on my machine (using VWD 2005 Express), I get the known error concerning the dll above. Unfortunately, I don't have VS on my machine, and my developer friends have looked on theirs and can't find the dll.

Is there any way that somebody could post this dll or email it?

You need to install the core bits

http://ajax.asp.net/default.aspx?tabid=47

Follow Steps 1 and 2

The resulting files will be located here Program Files\Microsoft ASP.NET\ASP.NET 2.0 AJAX Extensions\v1.0.61025

But you won't have to do much - just try the re-install after steps 1 and 2 are done/.

Visual Web Developer is enough to get you the Design DLL. More info here:http://forums.asp.net/thread/1458971.aspx
