    <p>I don't know if it will work in your particular case, but I've been in a similar (though probably less stressful) situation in the past, and I <a href="https://stackoverflow.com/questions/714666/is-it-appropriate-to-extend-control-to-provide-consistently-safe-invoke-begininvo">came up with some code</a> that let me marshal more-or-less arbitrary code from a background thread to the UI thread. This was written in the era of WinForms.</p> <p>This may provide a lower-risk technique for you to throw some computation back on some background threads and marshal your UI updates more easily to the foreground without a full re-architecture of the threading model (or lack thereof).</p> <p>Regarding performance of the UI, sometimes the best way to make it faster is to do less. The application I was working on when I created that linked code was parsing hundreds of megabytes of strings to manually munge some xml. Replacing immutable strings with stringbuilders took the operation from an OOM failure condition to completion within 5 minutes of wall-clock time. Then I noticed that, for every element it parsed, it updated the UI. I tweaked that code to update the ui every 50 elements or so, and that took it down to a fraction of a minute. Turning off all UI updates knocked the time down to a few seconds.</p> <p>Have you considered not-updating the UI until the calculations are complete, perhaps just running a progress bar instead? One other possibility (off the top of my head, dunno how evil it is) would be to queue updates as lambdas in a dictionary that is keyed off of the control getting updated. That way you could replace redundant updates to values if a single control is updated multiple times, e.g. (This assumes that the app isn't reading values directly from the UI to perform calculations, of course. Which it probably is. :( )</p>

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.
