ASP.NET IIS and framework

I have one ASP.NET web application projrct, created in Visual Studio 2008, .NET 3.5 Framework, IIS 6.1 and I'm using Ajax updatepanel, cache options for caching the datatable in a gridview. This project is working good in local, but when I deployed in a cert environment (.NET Framework 2.0 and IIS 6.0) I faced that caching issue.

So that, now I'm trying to change the proje开发者_如何学运维ct from 3.5 to 2.0 framework. But I'm facing an Ajax update panel error.

How can this problem be fixed?

You mean the target framework? You can right click the application name and then click on Property Pages, in that go to Build and then choose the target framework to 2.0.

Also, have a look at this: http://msdn2.microsoft.com/en-us/library/bb398791(VS.90).aspx reference : http://forums.asp.net/t/1194067.aspx

It will not be very straight forward though. As there may be some language features that are only available in 3.5.

The ASP.NEt AJAX framework for ASP.NET 2.0 has a separate DLL you have to install manually from this link: http://www.microsoft.com/downloads/en/details.aspx?FamilyID=ca9d90fa-e8c9-42e3-aa19-08e2c027f5d6&displaylang=en

You'll have to use an older version of the AJAX control toolkit too; the latest is only supported on 3.5 and 4.0.

HTH.
