I used to customize the list item forms (new/edit/display) in the farm solution which is quite straight forward. Now, I am working on a project which only allows sandboxed solutions to customize the list item forms. Obviously, I am no longer able to deploy the dll to the GAC or bin. I think of two solutions, one is to create a visual webpart which requires quite a bit of heavy lifting work. The other solution would be using InfoPath form which require less coding and has the flexibility of adding repeated sections. I kind of prefer the InfoPath form approach. But I am not sure whether there will be some kind of difficulties/limitations during the development.
Did anyone ever customize the list item forms in the sandboxed solutions? Could you share your experience?
Thanks,
Perry
Another option is also to create a html form using form7 http://forms7.codeplex.com/ looks really promising.
Here is a demo http://www.sharepointhillbilly.com/demos/SitePages/SampleForm.aspx
