This is a weird one.
Long story short: wrote a usercontrol using AJAX. Used return of smart part v1.3 to plug it into a sharepoint 2007 (development) site.
Works perfectly!
Moved it all to a production server – modified the web.config file to be exactly like the development site. It’s not working.
It’s weird because, I’m pretty sure the ajax is actually working, since the updateprogress is working, and I get an error in my ajax_endrequest js handler – after my second ajax request (as in – I press a button once, nothing, I press it again) I get:
“Invalid postback or callback argument. Event validation is enabled using in configuration…”
I have a linkbutton with javascript__doPostback, which seems to work – at least it’s running the code – but it’s not updating anything in the updatepanel.
Another example of it not working:
I have a tab-panel, and a listbox set to autocomplete. In the selectedindexchanged I change the active tab panel – but this isn’t working. When I do it twice I get the same aforementioned error back in my javascript end request handler.
Can ANYONE point me in ANY direction!? 🙂
Okay…
I have to vent. This problem took me way too long to fix.
The problem was in the masterpage in sharepoint. Since I wasn’t using the default masterpage, apparently this line:
Was outside the tag – when it’s moved down inside it (which is is in the default-masterpage, I was using on my development machine), everything works great -.-
I hate sharepoint sometimes…
