    <p>I solved this by using the link provided by astander above. I simply create an object in the HttpContext.Application to store progress variables, and then Set the method which does my processing inside a new Thread.</p> <pre><code>// Create the new progress object BatchProgress bs = new BatchProgress(0); if(Application["BatchProgress"] != null) { // Should never happen Application["BatchProgress"] = bs; } else { Application.Add("BatchProgress","bs"); } //Set up new thread, run batch is the method that does all the processing. ThreadStart ts = new ThreadStart(RunBatch); Thread t = new Thread(ts); t.Start(); </code></pre> <p>It then returns after the thread starts and I can use jQuery to get the Application["BatchProgress"] object at regular intervals. At the end of my thread the BatchProgress object has its status set to "Complete", then when jQuery queries it, it sees the complete status and removes the progress object from the application.</p>

    1. COThis may seem to work in testing, but you have two big problems here. The first is that if no one visits your site for a while, your processing batch might get killed off. The second is that the HttpContext.Application() item is _shared_ by all users of your site, so one user could end up over-writing another user's batch reference and see their progress information. Instead, you need to build a windows service and talk to that.

    2. COOh I did not know the batch would be killed off, that's a bit of a concern. The batch reference will not allow overwriting however, the functionality required to use the page is only available if the Application["BatchProgress"] is equal to null, otherwise the server controls are removed from the page and instead the BatchProgress is displayed. It will only be 1 user using this on an administration site, so I only need 1 batch at a time. The batch will be run weekly. How long before my processing batch will be killed off?

    3. COIt depends on a setting in IIS, and how much traffic your site gets. I think the default is something like 20 minutes of idle time, but my memory is fuzzy on the exact time limit. After that, the app pool hosting the site is shut down. So if you have even a popular site on the public internet, you're fine. If this is in it's own app pool and only one person ever visits it once a week, you could have problems.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
