I wrote a Web Part that I dropped on the root site page. That Web Part adds a list. This works great on the main page. That Web Part uses a custom list. Both the list and the Web Part were developed in VS 2010.
Issues/Steps - Sub Site
- I then activate the custom list feature on the sub site and that list shows up.
- I add my Web Part to the page.
I get the error:
Item does not exist. It may have been deleted by another user
This list is there on the sub-site. I do not get why the Web Part cannot find the list? It works well on the home page, the root site, but not on a sub site.
