Question

I have a Projects entity. The list of Projects is displayed in a Scaffolded List View as shown below. The Edit-Details-Delete are ActionLinks produced by the template.Each is linked to a new controller action and loads another View

ProjectName  | Created By | Created On | Status |
-------------|------------|------------|--------|--------------------
Test Project | USER1      | 12/31/2010 |  NEW   | Edit |Details |Delete

Each Project has a status- New,Approved,Denied.
I want to add links to the list called Approve and Denied which do not load a view. They just change the status of the project. I believe these will be HTTP Post Links. I have googled and not found a good working example of this.

ProjectName  | Created By | Created On | Status |
-------------|------------|------------|--------|------------------------------------
Test Project | USER1      | 12/31/2010 |  NEW   | Edit |Details |Delete|Approve|Denied

Answer 1

You could use AJAX:

@Ajax.ActionLink(
    "approve project", 
    "Approve", 
    new { projectId = item.ProjectId }, 
    new AjaxOptions { HttpMethod = "POST" }
)

and you will of course have a corresponding controller action that will take care of approving a project:

[HttpPost]
public ActionResult Approve(int projectId)
{
    ...
}

You could also use the OnSuccess and OnFailure properties of the AjaxOptions to define respective javascript functions that will be called in case of those events.

Needles to say that for the Ajax.* helpers to do anything useful you need to include the jquery.unobtrusive-ajax.js script to your page:

<script type="text/javascript" src="@Url.Content("~/scripts/jquery.unobtrusive-ajax.js")"></script>

and must have enabled unobtrusive AJAX in your web.config:

<appSettings>
    <add key="ClientValidationEnabled" value="true" />
    ...
</appSettings>
