Hi , I use AJAX my project but I have a problem … When I drag and drop the ScripManger in my page , this error will be occur : Element 'ScriptManager' is not a known element. This can occur if there is a compilation error in the Web site. Although I don't have any other errors in my website .. What is a problem ?? Please help me …

You must copy the file named "System.Web.Extensions.dll" to the folder named "bin" in your project.

The default path of the file is "C:\Program Files\Microsoft ASP.NET\ASP.NET 2.0 AJAX Extensions\v.1.0.61025\".

Hi ,

Thanks for your reply ..

I found the "System.Web.Extensions.dll" as you describeBut I don't have folder named "bin" in my website folder !!

Is there in any folder else ?? or can I found this folder in another place ??

Thaaaaaaaanks..

You could add a folder named "Bin".

Or add reference in the webside then you can see the folder.

I do that – add new Bin file- and but file in it .. but it still the same error !!Note : when I use update panel it also appear the same error but it work ( I means flicker don't appear ) What is the problem ?

also I note that this error occure when the page is from master .. but if it defult page and don't inherint from mster then this error will be appear ..

Please help me ...
