In SharePoint Foundation 2010, I have a Site > Subsite structure in which all Subsites were created with a template, and house the exact same folder structure. What I would like to do is create a top-level "Portal Page" belonging to the Parent Site that has web parts that list the contents of a particular Document Library for a site that is selected by the user. So, consider:
- SubsiteA (has Accounts Document Library)
- SubsiteB (has Accounts Document Library)
- SubsiteC (has Accounts Document Library)
Each Subsite has the same document libraries. On the ParentSite's default page, i want to display a "master view" of the document library, but limit it to see the library of the site they have selected. So maybe, if I go to
...then my Portal Page will display a view of the Accounts Document Library belonging to SubsiteA. If I have SubsiteB in the query string, display a view of the Accounts Document Library in SubsiteB (and so on). Do I need a custom web part for this? Can this be accomplished in SharePoint Designer? I definitely don't see this as a possibility in the UI.
