View Refresh?

lcbenson · August 23rd, 2011, 01:09 PM

I am having an issue with MVC3 Views not refreshing which is the main reason I purchased the book though I am happy to have it.

Summary of problem:
1. I have a view with a table that gets loaded with a collection of Model items for a WCF Service. Also has a create item link
2. I click the create item link which takes me to a create item view (form). I complete the form and submit, the database gets updated and by debugging I can verify that the class variable in the HomeController (list of items) includes the new item created.
3. Submitting the form take me to an Item Details View, displaying the properties of the item I just created. The Details View has a Back to List action link.
4. Click the Back to List action link, takes me back to the Item table in step 1 above but no changes are displayed in the table. I can verify that the SQL database has been unpdated as well as the Class variable in HomeController. Interestingly enough, I put a break point in the action controller and when I click on the âBack to Listâ actionlink from the Details View, the code in the HomeController is not even invoked! Its like it isnât even trying to do anything.

So I thought that maybe the view was being cached, I tried everything I could find online about disabling caching to no avail
I canât help feeling like I am missing something basic. Any help would be greatly appreciated.

Since this is a mobile website, I have included the following script and css in the head section of my _LayoutMobile.cshtml

http://code.jquery.com/mobile/1.0a3/...e-1.0a3.min.js
http://code.jquery.com/mobile/1.0a3/...-1.0a3.min.css

These includes format the website into an almost "App" like feel. However, if I remove these two form my _LayoutMobile.cshtml, my views update no problem. However, these removes all the formating and special scripts that really make the site.

Has anyone else run into a problem similar to this? I am going to dive into the jQuery and see if I can figure out whats going on, if I do, I will post the answer

Leon -

It looks like the issue you're dealing with isn't specific to ASP.NET MVC, it's with jQuery Mobile. jQuery Mobile has some built-in caching, and the simplest solution is to disable the caching where it's not needed.

Here are a few links with some options on how to do that:

Thanks for the reply,

that was the problem, I added the following code in my _LayoutMobile.cshtml

Code:

<script type="text/javascript">
        $(document).bind("mobileinit", function () {
            $.mobile.ajaxLinksEnabled = false;
        });
</script>

NOTE: This code needed to be added BEFORE I called my Mobile jQuery script.
