    <p>Alright so when the web part loads I pull from a list like so in the CreateChildControls() function:</p> <pre><code>String userGroup = GetProfileProperty(SPContext.Current.Web.CurrentUser.LoginName);//get user login's newsgroup // "All"; if (!string.IsNullOrEmpty(userGroup) &amp;&amp; !userGroup.Equals("All")) { qry.RowLimit = 5; camlquery = "&lt;Where&gt;&lt;Contains&gt;&lt;FieldRef Name='Intended_x0020_Audience' /&gt;&lt;Value Type='MultiChoice'&gt;" + userGroup + "&lt;/Value&gt;&lt;/Contains&gt;&lt;/Where&gt;&lt;OrderBy&gt;&lt;FieldRef Name='Start_x0020_Date' Ascending='False' /&gt;&lt;/OrderBy&gt;"; qry.Query = camlquery; items = newsList.GetItems(qry); //Print items inside a ajax panel.... } else { qry.RowLimit = 5; camlquery = "&lt;OrderBy&gt;&lt;FieldRef Name='Start_x0020_Date' Ascending='False' /&gt;&lt;/OrderBy&gt;"; qry.Query = camlquery; items = newsList.GetItems(qry); ////Print items inside a ajax panel.... } </code></pre> <p>I do not use paging yet, but I have stored the query list in a var items. When the user clicks a button the update panel clears out the current controls and does another query to get the new items, but this time I use paging.(see below)</p> <pre><code> int lastID = items[items.Count - 1].ID;//last news item id of current page //Get Web Context SPWeb web = SPContext.Current.Web; //Clear old panel UpdatePanel up = (UpdatePanel)FindControl("Panel"); up.ContentTemplateContainer.Controls.Clear();//clear container of old news items SPQuery qry = new SPQuery();//get query qry.RowLimit = 5; string camlquery = "&lt;OrderBy&gt;&lt;FieldRef Name='Start_x0020_Date' Ascending='False' /&gt;&lt;/OrderBy&gt;"; qry.Query = camlquery; SPListItemCollectionPosition position = new SPListItemCollectionPosition("Paged=TRUE&amp;p_ID=" + lastID.ToString()); qry.ListItemCollectionPosition = position; items = web.Lists["News Wire"].GetItems(qry);// newsList.GetItems(qry); //print items inside ajax panel.... </code></pre> <p>It does change the page, but it returns more items than necessary. I'll get five when the webpart first loads, but when I click the button that triggers the event to get more list records, I get the first item of the next page and also the first page's first 3 items. Note: My list only has six items in it. I limited my RowLimit to 5, but when I load the second page I get 4 items and 3 from the first page. </p>

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.
