This was a working web application where all I have done is upgraded from 8.2 to 8.3. On my page I have an update panel that only contains <asp:> tags, no infragistics stuff (there are infragistic tools on other places on the page, but not inside the updatepanel). When a link is clicked on inside the updatepanel, it does not seem to be posting back to the server. A breakpoint in the menuButton_Command procedure is no longer being hit. Again, the only change to the app was ugrading the web.config to point to the newer 8.3 infragistic tools. Seems like changes to the infragistics items is interferring with the updatepanel. Any ideas?
Oh... this is Framework 3.5
Without seeing that section of code it is a little hard to help on this as there are a million things that can happen in a 3.5 web.config not to mention the obvious <asp:UpdatePanel><ContentTemplate> stuff... I know a lot of people use the gac and link it via web.config but i for one don't because of upgrading dll files etc. I never like to install etc. so I just drop them in the bin folder and call them that way...
I am using 8.3 right now in a 3.5 site with ajax in and outside ig controls so it sounds like you are missing something somewhere...
The ONLY thing that changed was installing Infragistics 2008 v3 and updating the web.config to change the referernces from v8.2 to v8.3. In other words, all the ajax stuff was working before. Once I set the references back to v8.2, everything started working again.
After you changed the web.config file did you change the <% Register in the page to Version=8.3.20083.1009?
Didn't need to as I have added all the tag prefixes to my web.config:
<add tagPrefix="ignav" assembly="Infragistics35.WebUI.UltraWebNavigator.v8.3, Version=8.3.20083.1009, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb" namespace="Infragistics.WebUI.UltraWebNavigator"/>
etc....
