Question

Does PartialView do what I think it should (but doesn't)?

Answer 1

+1 A:

It works here. Are you sure the jquery load() is called?

Yeah. As mentioned, I have used a breakpoint in the controller method and it definitely fires. I'm glad it works for someone - it means I must be on the right track.

A:

I'd hate to ask but are you including the jquery script somewhere? I've been asked all to many times by others why jQuery isn't working with their MVC project. Solution being adding a tag to their master page.

Yep, it's there.

Answer 3

+2 A:

In one of the most bizarre fixes I've found yet, it would seem that (in my case), adding a

<html><head><title></title></head><body>

before the user control code, and a

</body></html>

after the user control code, gets around the problem. Without these, the control returns nothing.

Now, it is perfectly possible that this is due to some strange issue caused by the site's evolving from Preview 3 -> Preview 4 -> Preview 5 -> Beta -> RC1, so I wouldn't be surprised if I am the ONLY PERSON IN THE WORLD getting this issue, but there you have it.

If anyone does find a better answer, please add it here...

Answer 4

A:

Hey Darren, can you try using Fiddler2 and see what it shows as the response? I have a feeling that if partial view is being executed, as you said, this might not be an issue with MVC. Here's something to try to reduce the problem down to its core.

When you make a direct request to /MyController/GetList, does it return the correct HTML?

Add a "foo.html" file to your website containinng the HTML output you expect from the partial. Change your jQuery code to request that foo.html instead:

$('#MyDiv').load("/foo.html");

Does that work? One thing you can do with the load method in jQuery is provide a CSS selector. So as a workaround, you could wrap the partial with the HTML head, body tags as you did in your other answer, but then add a CSS selector to the load method to grab only the portion you want like so:

$('#MyDiv').load("/MyController/GetList #stuff-i-want");

Without the <html> tag cruft in there, Fiddler2 indicated a response length of 0 bytes (yet, as mentioned, the view does get evaluated, verified by a Debug.Print statement), but gave the correct output with the tags. The CSS selector isn't a bad idea, but not required (jQuery seems to strip it off).

Answer 5

A:

It just works to me. I created a sample

The View

<div id="sam"></div>

<% var url = Url.Action("GetList"); %>
<script type="text/javascript">
    $(document).ready(function() {
        $('#sam').load('<%=url%>');
    });
</script>

The Partial View - GetList.ascx

<%@ Control Language="C#" Inherits="ViewUserControl<IEnumerable<string>>" %>
<ul>
<% foreach (var s in Model) { %>
    <li><%=Html.Encode(s)%></li>
<% } %>
</ul>

The Controller

[AcceptVerbs(HttpVerbs.Get)]
public PartialViewResult GetList()
{
    return PartialView(new[] { "Hello", "Foo", "Bar" });
}

Hope this helps.
