You are on the right track and it is possible to retrieve results for lists in different webs. The following example shows how to retrieve items from the default 'Tasks' or 'Workflow Tasks' lists and works with task lists created at the root level and within a sub site. <pre><code> SPSiteDataQuery q = new SPSiteDataQuery(); q.ViewFields = "<FieldRef Name='Title'/><FieldRef Name='Priority'/><FieldRef Name='Status'/>"; q.Webs = "<Webs Scope='SiteCollection' />"; q.Lists = "<Lists BaseType='0' />"; q.Query = "<Where><Gt><FieldRef Name='ID' /><Value Type='Number'>0</Value></Gt></Where>"; DataTable results = new DataTable(); using (SPSite site = new SPSite("http://sharepoint")) { using (SPWeb web = site.OpenWeb("subsite")) { results = web.GetSiteData(q); } } </code></pre> I've written it using a hardcoded URL so you can run it inside a console application for testing but you can replace the using statements with something like <code>SPWeb web = SPContext.Current.Web;</code> when you put this inside a web part. A few other things worth considering: <ul> <li>The lists you are querying must contain all the fields in the ViewFields element</li> <li>Multi-lookup fields do not work well with the SPSiteDataQuery (single value lookup fields are ok)</li> <li>The u2u CAML builder tool is also useful for testing CAML queries. See <a href="http://www.u2u.be/Res/Tools/CamlQueryBuilder.aspx" rel="nofollow noreferrer">http://www.u2u.be/Res/Tools/CamlQueryBuilder.aspx</a></li> </ul>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
