I have used parts of the AJAX Toolkit for some time now and have had success.
Moving forward past VS2010 that has changed. I had a great deal of trouble getting some of it to work with VS2013 fw4.0 and 4.5.
I used the web browser debugger and could see that I was stepping through jQuery code. Since I had not put any jQuery of my own on the website it had to be the AJAX Toolkit code.
I started asking around to programmers I know and the consensus seems to be that the AJAX Toolkit is no longer reliable. What works today might not work in the future if a web site is updated and I am in fact finding that out. One person told me that it is open source and that has lead to some of the problems.
I used the Popup control extenders in the past but they no longer work in the newer version of the AJAX Toolkit - jQuery errors.
It could be that certain versions of the IDE, AJAX Toolkit and .net framework need to be synced up. Is there a guide some where that explains this?
Please comment on this and tell me what any of you think?
Thanks.
