Firstly, here's a link to the slides etc. Thank you to everyone who came along last night and apologies for my ListView problems. I've been trying to recreate them this morning and all worked fine in a new ASP.NET 3.5 site I created. My suspicions turned to a reference in my demo site and sure enough there was a reference to both System.Web.Extensions 126.96.36.199 (the current version) and 188.8.131.52 (the version for the ASP.NET 3.5 Extensions). How that got in there is a mystery to me, unless I inadvertently added an ASP.NET 3.5 Extensions item to the site (which implicitly adds the reference) and deleted it.
That's quite plausible but I must have done it yesterday afternoon while testing the demos and then zipped up the problem into my demo "saved state". The problem is easily resolved by removing this reference - something I should have thought to have done last night but often the obvious doesn't easily spring to mind with 200 people watching your demo fail... :-)
I shall go and fix up my "saved" version to make sure this doesn't happen next time!
I would also point you to my blog entry on Some ASP.NET 3.5 ListView Control Examples so you can see a few examples of the same data rendered in different ways in a ListView control and download the source.
Don't worry about the problems last night. I thoght you handled it very well and we got to see all that was important.
Diagnosing problems in front of 200 people must be VERY scary!
Thanks for the session it was great.
Mike - I really enjoyed your session on Thursday in Manchester, I thought you had more problems with the projector than the reference files ;-)
