UpdateTargetId ASP.NET Ajax...Where is it?

Question

Hello SO:

This is probably a silly question, but why am I unable to utilize Ajax in my project?

I should have all the necessary references:

System
System.Configuration
System.Core
System.Data
System.Data.DataSetExtensions
System.Data.Entity
System.Data.Linq
System.Drawing
System.EnterpriseServices
System.Runtime.Serialization
System.Security
System.Web
System.Web.Abstractions
System.Web.Extensions
System.Web.Mobile
System.Web.Mvc
System.Web.Routing
System.Web.Services
System.Xml
System.Xml.Linq

I also added Ajax script references to my MasterPage, but this doesn't really matter at the moment since I cannot write code to utilize it.

Do I have to write a wrapper class that exposes these properties to my view? Or am I missing something else?

Thanks

code:

<div>
    <p>
        <%= Ajax.ActionLink("Test","AjaxTest",new AjaxOptions(UpdateTargetId = "test")) %>
    </p>
    <p id="test" visible="false">
        Test Text
    </p>
</div>

Answer 1

Make sure that you have referenced this assembly (which you obviously have give your list of using statements):

System.Web.Mvc.dll

and also make sure that you import this namespace as well:

System.Web.Mvc.Ajax

Answer 2

as stated above, add the System.Web.Mvc.dll to your project, add a reference to System.Web.Mvc.Ajax, and use the following js files:

<script src="<%= Url.Content("~/Scripts/MicrosoftAjax.js") %>" type="text/javascript"></script>
<script src="<%= Url.Content("~/Scripts/MicrosoftMvcAjax.js") %>" type="text/javascript"></script>

to actually start using it.
