Further Details:
I am using windows XP Pro in a 2003 domain environment with the projects stored on a network share. One of the two projects I am having trouble with has been around since VS 2003. Last year, before opening project A in VS 2005 I installed the Pre-SP1 WAP support I then converted the project using instructions from ScottGu's Blog. I did all of this in the last half of last year. Fast forward to 2 weeks ago, I began to learn about all the cool features of AJAX and installed (still pre-sp1) the AJAX extensions for VS 2005. I then followed the instructions in a video from this site about how to AJAX enable older apps. After doing that things still seemed ok. I then came across a problem using AJAX controls with Master pages. Different forums suggested that SP1 would solve this problem and indeed it did however when I drag any control AJAX or otherwise onto a page (source mode or design mode) the controls fails to declare itself on the designer.vb page.
Project B is a WAP project that I created fresh in VS 2005 before adding AJAX and SP1. I decided I'd like to add AJAX functionality to this project too so I again followed the video directions to AJAX enable my project. I am now experiencing the same difficulties when dragging controls into the project to use.
Workaround?:
Although this doesn't tell me what may have gone wrong in my original projects I decided to create a new AJAX enabled project (post SP1) and just copy needed elements, pages, and code from the old project into the new one. This seems to be working for both projects. Now, when I drag and drop any control including the AJAX ones the controls are being declared correctly in the designer.vb pages. I will consider my problem solved but if anyone has some idea as to what may have happened I'd still be interested.
Thanks everyone for providing such a wonderful online community. I have solved many an issue through these forums.
