Question

I am having issues with retrieving list items from a different site collection. I don’t have issues when trying to recieve list items from within my current site collection. For example, http://myintranet.com/Departments/IT works. But http://myintranet.com/sites/Departments/IT returns an error.

if (!String.IsNullOrEmpty(SiteName) && !String.IsNullOrEmpty(SPContext.Current.Web.Url))
    {
      SPSecurity.RunWithElevatedPrivileges(delegate()
      {
        using (SPSite intranetSite = new SPSite(SPContext.Current.Web.Url))
        {
          using (SPWeb currentWeb = intranetSite.AllWebs["/sites/projects/Physics"])
          {
            SPList postList = currentWeb.Lists.TryGetList("Issues");                

            if (postList != null)
            {
              IssueList.DataSource = postList.Items.GetDataTable();

              IssueList.DataBind();
            }
          }
        } 

      });
    }

I haven’t used any different code to what I normally do when trying to recieve list items. The only difference is that this time I getting list items from another site collection.

Thanks for any help!

The problem is intranetSite.AllWebs. This will only get SPWeb objects under your current site collection.

You cannot infer another site collection directly from one site collection.

Even though /sites/projects LOOKS like chid site collection from /, it;s not. /sites is just a managed path. / and /sites/projects are at the same level of the site collection hierarchy.

What you need to do is to this:

if (!String.IsNullOrEmpty(SiteName) && !String.IsNullOrEmpty(SPContext.Current.Web.Url))
    {
      SPSecurity.RunWithElevatedPrivileges(delegate()
      {

          using (SPWeb currentWeb = new SPSite("http://server/sites/projects/Physics").OpenWeb())
          {
            SPList postList = currentWeb.Lists.TryGetList("Issues");                

            if (postList != null)
            {
              IssueList.DataSource = postList.Items.GetDataTable();

              IssueList.DataBind();
            }
          }

      });
    }
