I downloaded and installed the AjaxControlToolkit.Binary.NET35.zip.I added Accordion, and add Accordion panels. Building the web site always fails. There are several error messages, like, Type 'AjaxControlToolkit.Accordion' does not have a public property named 'AccordionPane'. I checked the web.config file there are two different versions of System.Web.Extensions and System.Web.Extensions.Design.One is version 3.5 and another is 1.0 See the copy followed,
i have installed ajax control kit successfully and all controls already came in toolbar tab named "Ajax Control toolkit"But when i try to design any page using with ajax control toolkit, follow error is coming:

I am using VIsual Studio 2008 , framework 3.5 but i don't know why in error information version is showing 2.0
i install tool kit according 3.5 framework.also note, framework built-in ajax tags i can use fine and they work properly.
i have installed ajaxtoolkit 3.5 but when i debug i am getting this error Could not load type 'System.Web.UI.ScriptReferenceBase' from assembly 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' even i have changed my tags to
I have an ASP.NET project and I want to use some AjaxToolKit Extenders on my pages.
The site is created in VS2010, set to Framework 4.0.
This is what I did:
1) Add reference "AjaxToolKit.dll" to my project.
2) Add to the toolbar the same file for the controls
3) Add "ToolkitScriptManager" to the page source.
This adds the declaration to the source as well.
Right after this I get the following error:
Reference required to assembly 'System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' containing the base class 'System.Web.UI.ScriptManager'. Add one to your project.
We are working on a web application and the target deployment includes Windows 2003 64-bit. When we run the application on the 64-bit OS, it gives the following error:
The entry 'asp:System.Web.UI:System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' has already been added
And if we remove the line <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>, it seems to work.
Can somebody understand the problem and take corrective action? The application does not compile on 32-bit OS without this.
I upgraded our Web App from VS2005 to VS2010 but is Framework 3.5 and Ajax 3.5.
I had some issues but managed to resolved most.
The last issue is it is not building.
I originally had a referrence to - System.Web.Extensions, Version=1.0.61025.0 which caused the app to crash but it built fine.
When I changed - System.Web.Extensions, Version=3.5.0.0, it refuses to build as it cannot find a custom control within the ajax control toolkit - tab panel.
It's the wierdiest thing, when I change back to 1.0.61025.0 it works but as soon as I go to 3.5.0.0 it can't find control "mnuCBO".
Also tried changing tagprefix in the webconfig but that also didn't help.
Maybe it a little thing or something silly that someone else has experienced.
I have included some parts of code from my master page.
By default ASP.NET 3.5 Web App project has references to assemblies System.Data.DataSetExtensions.dll and System.Web.Extensions.dll.
With System.Data.DataSetExtensions everything is clear for me, it contains such useful extension methods as DataTable.AsEnumerable() and DataTable.CopyToDataTable().
And what about System.Web.Extensions.dll? What useful members could you mention to use?
I've run into a problem with WCF REST Service. I get:
Could not load type 'System.ServiceModel.Activation.HttpHandler' from assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
when running inside of the IIS in an ASP.NET 4.0 AppPool.
The problem seems to occur only if:Running inside of IIS When ASP.NET Comaptibility is enabled
Running in Cassini - no problem it works properly. Running with ASP.NET compatibility off - no problem it works.
It appears that it's some sort of handler version conflict trying to instantiate the wrong version of the handler that in turn tries to load an older version of System.ServiceModel, but I haven't been able to trace this down.
Anybody seen anything like this before and have any ideas how to track this down further?
I've looked in ApplicationHost.config and the master web.config files for System.ServiceModel and HttpHandler references but no luck.
I moved a site to another server, it worked fine for a a while, but then crashed. I figured out that System.Web.Extensions.dll was missing, so I copied it again. After a while it was missing again. Using Process Monitor I figured out that IIS (w3wp.exe) deletes the file soon after I copy it to the bin folder. (CreateFile with "Read Attributes, Delete" access.)
I purchased a new computer and put all my development software on. Now when I load an asp.net 2.0 project I get the following error:-
Code: Error3E:RPPResolve-ITASPDotNET2.0HansooKwanDirections.aspx: ASP.NET runtime error: Could not load file or assembly 'System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.

One of the libraries I am including in my project makes use of System.Web.Extensions 3.5.0.0, which conflicts with my Framework 2.0 application, which uses (C:Program FilesMicrosoft ASP.NETASP.NET 2.0 AJAX Extensionsv1.0.61025System.Web.Extensions.dll). I can think of 3 possible solutions:
Ignore the warning and don't change anything. I am not sure what the application does to handle this. Add an assembly binding element to my web.config (see below) Configure the application explicitly to use different assemblies (I think this is possible, but don't know how to do it).
However, I am unsure of the implications of each of these decisions. The application seems to work perfectly fine even when I ignore the warnings (solution 1), but ignoring warnings that I don't fully understand bugs me...as does having warnings like this show up at all.
I'm having trouble moving a website from one server to another. It seems to be a problem loading multiple versions of System.Web.Extensions. The code uses version 3.5 in most places but a third party control appears to be needing version 1.0.6. I didn't think this was possible but it appears to be working in it's current situation.
Is there a way I can use the GAC version of System.Web.Extensions for the site but import a dll of version 1.0.6 just for these controls?

But it turns out that the OpenWebConfiguration(null) method call is returning the global web.config file, whereas I want the web.config file for this particular site. If I hard-code in the path to this particular site, then it works--but then my code isn't portable. There must be a way to open the web.config file for the particular site that the code is hosted on--isn't there? Could somebody point me in the right direction?nd, if there's another way I should go about trying to get the maxJsonLength attribute out of the web.config, let me know. I can't just instantiate a JavaScriptSerializer object and inspect the MaxJsonLength property, I already thought of that :-)

Errors :-

What i will do now? Also i used 'Microsoft.SqlServer.SmoEnum', Version=9.0.242.0 in VS 2005. (Are i have to change it to version=10.0.0.0? by adding reference to new version.) I also used crystal report.(Is there is anything to do with it?)
