    <p>I am using LongListSelector control with ItemRealized Event and its working fine but when I update the list which is assigned to ItemSource of LongListSelector the items in LongListSelector are not updating.</p> <p>Below is the code I am using in XAML.</p> <pre><code>&lt;phone:LongListSelector SelectionChanged="listBoxGroups_SelectionChanged_1" Grid.Row="1" x:Name="longListSelector" ItemTemplate="{StaticResource groupsItemTemplate}" Margin="0,100,0,0"&gt; &lt;/phone:LongListSelector&gt; </code></pre> <p>In code behind.</p> <pre><code> public GroupsMainPage() { InitializeComponent(); longListSelector.ItemRealized += longListSelector_ItemRealized; this.Loaded += GroupsMainPage_Loaded; } void longListSelector_ItemRealized(object sender, ItemRealizationEventArgs e) { if (!controller.IsLoading &amp;&amp; longListSelector.ItemsSource != null &amp;&amp; longListSelector.ItemsSource.Count &gt;= 100) { if (e.ItemKind == LongListSelectorItemKind.Item) { if ((e.Container.Content as Result).Equals(longListSelector.ItemsSource[longListSelector.ItemsSource.Count -7])) { connectToWebService(); } } } } </code></pre> <p>After receiving the response from web service I simply do the following.</p> <pre><code>private void WebServiceSuccessAction(Object obj) { GroupModel.getInstance().GetGroupResponse((GroupResponse)obj); if (GroupModel.getInstance().GetGroupResponse().Response.errorCode == 0) { controller = new GroupController(); if (fetchNumberofGroups &lt;= 100) { this.ResultList = controller.GetGroupList(); longListSelector.ItemsSource = this.ResultList; } else { controller.addNewGroupData(); this.ResultList = controller.GetGroupList(); } } else { List&lt;Error&gt; error = ConfigModel.getInstance().getConfigResponse().Response.data.errors; foreach (Error err in error) { if (err.code == GroupModel.getInstance().GetGroupResponse().Response.errorCode) { MessageBox.Show(err.text); } } } } </code></pre>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
