    <p>I have an Xaml file which contains Flow document &amp; List Item inside that Xaml File.<br> here is my code,</p> <pre><code> xmlns:p="http://schemas.microsoft.com/winfx/2006/xaml/presentation"; &lt;Book&gt; &lt;Ins&gt; &lt;p:FlowDocument&gt; &lt;p:List StartIndex="1"&gt; &lt;p:ListItem&gt; &lt;p:Paragraph&gt;Some Text.&lt;/p:Paragraph&gt; &lt;/p:ListItem&gt; &lt;p:ListItem&gt; &lt;p:Paragraph&gt;Some Text.&lt;/p:Paragraph&gt; &lt;/p:ListItem&gt; &lt;/p:List&gt; &lt;/p:FlowDocument&gt; &lt;/Ins&gt; &lt;/Book&gt; private FlowDocument _notes; public FlowDocument Notes { get { return _notes; } set { if (_notes!= value) { _notes= value; RaisePropertyChanged(() =&gt; Notes); } } } </code></pre> <p>I am able to load this document.. When I am trying to save this document by using XamlServices.Save, It is generating the below extra tags inside <strong>List</strong>..</p> <pre><code> &lt;av:List.SiblingBlocks&gt; &lt;x:Reference&gt;__ReferenceID13&lt;/x:Reference&gt; &lt;/av:List.SiblingBlocks&gt; &lt;av:ListItem.SiblingListItems&gt; &lt;x:Reference&gt;__ReferenceID9&lt;/x:Reference&gt; &lt;x:Reference&gt;__ReferenceID12&lt;/x:Reference&gt; &lt;/av:ListItem.SiblingListItems&gt; </code></pre> <p>When I am trying to Load this newly saved Xaml file, it is throwing an error "Collection property 'System.Windows.Documents.ListItem'.'SiblingListItems' is null." at Sibling blocks..</p> <p>I think my issue here is using Flow document as it is wpf typed object I can not use flow document (Wpf typed object) with XamlServices.Load()... Can I have any alternative for Flow document (Which is of not a wpf typed object)...</p> <p>I also tried with XamlWriter.Save but It does not work for me as I am using Genric class with parameteral constructor..</p> <p>Thanks in Advance..</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.
