I have designed a DVWP in SharePoint Designer 2010 that shows multiple items from a library (let's say it shows 1000 items for example) grouped by category. What I would like to do is show a loader image for the few seconds it takes to load all items.
How would you tell a script to do something when the last row of a dataset renders?
UPDATE: After turning on the AJAX loader, it looks like the rows themselves are loading pretty quickly (like 2 seconds). Each item has a thumbnail image attached to it, however, and those take several seconds to load. So assuming we have a thousand images, is there a way to dynamically determine the last one and then show a loader image until that one loads? Same result, but I realize that changes up the question a bit...
