I need to display a list from the parent site collection root as a Data Form Web Part in a child site in SharePoint 2010. This article seems to be talking about what I need.
But I'm not able to create a data source to the list in the parent from SP Designer. I'm logged in as administrator. Under Data Sources, I only see my site's objects, and the same thing under More Data Sources, and there's no option to add a new data source.
Is there a permission that needs to be changed to allow a site to see the root site's objects and create data sources to them? What am I doing wrong?
