Ajax Control Toolkit Installation in Visual Web Developer

by Nannette Thacker

Update 11/24/2011: For Visual Studio 2010 4.0 Framework users:

My blog post was written a  few years ago for 3.5 SP1. I needed to install the Ajax Control Toolkit for Visual Studio 2010 4.0 Framework and wanted to make sure there were no problems, so I googled "install ajax control toolkit visual studio 2010" and found this step by step guide:

 http://www.asp.net/ajaxlibrary/act.ashx

It installed perfectly for me the first time, so I'd recommend following the above link. There were just a few steps and voila!

Thanks! Nannette

Original Blog Post continues below for Ajax Control Toolkit Installation in Visual Web Developer:

To install the Ajax Control Toolkit, first download the zip file from http://www.asp.net/ajax/.

3.5 SP1 Release is here.

Unzip the files into any directory. Give it a name like "AjaxControlToolkit." 



Open your Visual Web Developer and right click in the Toolbox area. Select "Add Tab." 



Name the tab with something like "Ajax Tookit." 



Right click the new tab area, and select "Choose Items..." 



This will bring up a dialog box to "Choose Toolbox Items." Select the "Browse" button. 



Browse to the directory where you unzipped the Ajax Toolkit files. There is a "SampleWebSite" directory within your "AjaxControlToolkit" directory. Browse to the "Bin" directory within the "SampleWebSite" directory. 



Find and select to open the "AjaxControlToolkit.dll" file. 



The Choose Toolbox Items dialog will appear, this time with the Ajax Tookit controls selected. Select the "OK" button. 



Open or create a web form within your project. Now when you open your toolbox, you will see all of the Ajax Control Toolkit controls, ready for use within your applications. 


May your dreams be in ASP.net!

Nannette

Am I the only one who thinks it is utterly ridiculous that we're supposed to use a dll from the WebSite project as the main reference for the toolkit?  Why isn't this in a separate class library project?

# February 18, 2008 11:27 AM

nannette said:

skain,

I fully agree. I think it should automatically be in the toolkit, or at least an option you can turn on or off without having to download a project and grab a .dll.

I would suspect in future versions of VWD that the toolkit will be an automatic part of the release. But who knows?

Do you need to any of this in VS2008? or is it all built in and done for you?

# February 25, 2008 2:40 PM

nannette said:

Sorcerdon,

I can't answer that. I hope someone else knows the answer.

I don't believe the AjaxControlToolkit is built into VS2008.  Ajax components are, but not everything that's in this toolkit.

Great post Nannette.

I do have Visual Studio 2008 installed now, and no, the Ajax toolkit is not a part of it.

nannette said:

Cindy,

I have two computers. I tried installing this on my new computer, which does not have a Microsoft ASP.net folder. And I get the same error.

I don't know what is causing that and why it does not work on this other computer. I also don't know why there is not an ASP.net folder, although I do asp.net development on this computer all that time.

Maybe someone more knowledgeable can offer guidance.

I am also getting the same assembly error as nannette and cindy with vs2008. any ideas?

# April 3, 2008 11:46 PM

wildgoosed said:

Cindy and Nannette I have figured out the problem.

With VS2008, you must download/use the .dll from the Ajax Control Toolkit Framework 3.5 package.

Isaac said:

Thanks so much for posting this. I've been looking through MS and Codeplex docs for something like this. Wouldn't you know that it ain't in plain sight. Oh well, thank you just the same. A very very very helpful blog posting.

As far as appearing in MS's default install of VWD or VS 2008, this toolkit is a community-built thing. It's not a MS thing, so they're not going to load it for you out-of-the box, however comma, they should at least help users by doing a simple explanation as to how to load the controls.

Nannette, send them a bill for our pain and suffering.

" it is utterly ridiculous that we're supposed to use a dll from the WebSite project" Even I thought the same. initially i thought that this url provides a way around .There must be some other way. It was very odd that you need to specify the tab name by yourself. I got convinced after seeing the comments that i am not the only one to be fooled.

Thanks Nannette, however I have a problem upon uploading it in the toolbox... It gives this error Message:

The was an error loading types from assembly 'D:\Program Files....

'Could not load file or assembly 'System.Web.Extensions, Version=3.5.0.0, Culture=nuetral............ or one of its dependencies. The system cannot find the file specified.'

How can I resolve this issue? thanks in advance

anybody who knows how to resolve the issue??? Please help

# November 4, 2008 11:06 PM

nannette said:

rhiana,

I was able to reproduce your error by attempting to load the toolkit into a non 3.5 web site.

Make sure you have created your website under 3.5 framework if you are using the 3.5 toolkit. Otherwise, download the older toolkit to go with the right framework.

Nannette

# November 11, 2008 4:58 PM

nannette said:

rhiana,

I noticed I had loaded the toolkit successfully, and then went in and it was missing. So when I tried to load it again, it failed with same error, even though the project was 3.5

I closed down some other VS2008 windows to free up memory and it worked fine.

So try making sure you have everything else closed out.

Nannette

thanks a lot for the post. Your solution applies to vs2008.

I have vs2005 on my machine.

When I try to load the various controls to my tool box by pointing to the ajaxtoolkit dll, an error appears that goes like this "'There was an error loading types from assembly C:\programfiles\...ajaxtoolkit.dll' Could not load file or assembly 'Systems.web.extensions version=1.61025.0 culture=neutral, public token=... or one of its dependencies. The system cannot find file specified"

Please do you have any ideas.

Make sure you have installed the ASP.NET AJAX Extensions 1.0 before trying to install the Toolkit!

I only speak VB.  I downloaded the AJAX Control Toolkit and it looks to me like it is in C#.  Is there a VB version or should I stop living in the 20th century and learn C#?

# March 25, 2009 8:42 AM

nannette said:

The toolkit works for both VB and C#. It uses an asp.net control, which is supported by both languages.

I'm unsure what you're seeing.

THANK YOU NANNETTE...  I upgraded to Vista under a "Clean Install" so I had to re-install my VS2008.  I have searched high and low for the toolkit because I could not remember how I had originally installed it.  Your post was the answer.  Incidently, I do like Vista and I love VS 2008 but why is it so difficult to add the toolkit???  Are there any more recent updates since August 2008 and if so what &*^% will I have to go through to install them?

Thanks again so much
