You can view the page by going here: http://jacksonclarkgalleries.com/ and then selecting any of the "Artists"
and "Collections"
with the left-side buttons. I figured that AJAX would be super for these "generic"
pages (there really are only two aspx/aspx.vb file pairs for either showing *any* Artist or any Collection (and the particulars are dynamically built from entries in the database which correspondingly point to the image file pairs). HOWEVER ... here's where the wrinkles come in. In following the "how to"
video, there seems to be a glitch that I'm getting that the video doesn't encounter. (Oddly, I have observed that a lot of these Microsoft "How Do I"
videos strangely use what I would call the "Benihana of Tokyo"
trick -- to "save time"
sometimes they seem to paste in a large quantity of code from an unseen source -- much like dumping the pre-sliced pieces of shrimp onto the cookery whilst the blazing knives are putting on the "floor show"
[watch closely!].) In this instance, instead of starting with a demonstrable running non-AJAX (3.5) app, the instructor builds a simple one, so it's really NOT like converting an existing app at all, is it? ANYWAY ... back to the anomaly: My "MIDDLE"
section above it a totally separate table, so I figured that I could just surround it with the opening and closing "UpdatePanel"
definition and be off flying into AJAX nirvana, right? Sorting through 40 or 50 [red-type] error messages it seems I've been laboring under a misunderstanding. The "root"
error message is: Warning 68 Validation (XHTML 1.0 Transitional): The element 'table'
cannot be nested within the element 'updatepanel'. D:\ZZZ_VISUAL_WEB_DEVELOPER\JCG9_AJAX\Artist.aspx 60 26 D:\ZZZ_VISUAL_WEB_DEVELOPER\JCG9_AJAX\ Huh? So there are a limited number of control types which can existing within an UpdatePanel? My whole design here is predicated on a table-ish layout that would surely benefit from being the "isolated update"
item, right? Is the AJAX approach only good for things which are NOT laid out using Tables? What else would you use instead? Any guidance gratefully accepted!
