    Hi Everyone,

    I followed the instructions on the site to add the
    AjaxControlToolkit (AjaxControlToolkit.dll) to the VWD 2008 toolbar:

    However, when I selected the AjaxControlToolkit.dll and clicked OK
    (as the instructions say to do), I get the following error:

    ' There was an error loading types from assembly
    Could Not load file or assembly "System.Web.Extensions",
    version 1.0.61025,0....'

    Do I need to place the Ajax Control Toolkit or any files in any
    particular directory?

    Also, another weird thing is that when I select "New Project" I see
    under my template 3 icons that say Ajax Web Site.

    I even tried to unistall VWD 2008 and install it again. Regular
    and .Net 3.5 work fine. The Ajax Control Toolkit are the ones that I
    can't add to the Toolbar.

    Can someone please help?

  2. Hello ,

    You can put that dll to any folder or to GAC and then add reference to that
    dll in your VS project.
    It should work fine.

    Hi Michael,

    I tried placing the dll in other directories (right in the .Net
    directory). Then I added
    it to the project again (right clicked on Solution Explorer and added
    it to the Project).

    Then I need to add it to the Toolbox to have the controls available.
    I created a new
    section called Ajax Control Toolkit. I then right clicked inside that
    section and selected
    Choose Items. I browsed to that directory and selected the
    Then it still gives me an error "Can't load assembly

    I'm still unable to place the Ajax Controls in the Toolbox.

    Any ideas on what else can I do to get that working?

    Have a nice day and thanks in advance.

    Add AJAX Contol Toolkit

    I had a simular issue. Try this. Add a new tab to the toolbox. Within the new tab, select Choose Items and select the AjaxControlToolkit.dll file to add the controls to the toolbar.
