    <p>I have a xml file:</p> <pre><code>&lt;?xml version='1.0' encoding='windows-1251' standalone='yes'?&gt;&lt;XML&gt; &lt;Result&gt;Ok&lt;/Result&gt; &lt;Error&gt;&lt;/Error&gt; &lt;Remark&gt;&lt;/Remark&gt; &lt;Data&gt; &lt;Theatres&gt; &lt;Theatre ID='1' ShowBusyPlaces='1'&gt; // maybe more than one &lt;Name&gt;&lt;![CDATA[PlaceName]]&gt;&lt;/Name&gt; &lt;NameFull&gt;&lt;![CDATA[PlaceName]]&gt;&lt;/NameFull&gt; &lt;Remark&gt;&lt;![CDATA[]]&gt;&lt;/Remark&gt; &lt;Address&gt;&lt;![CDATA[]]&gt;&lt;/Address&gt; &lt;Halls Count='3'&gt; &lt;Hall ID='1'&gt; &lt;Name&gt;&lt;![CDATA[Redisson]]&gt;&lt;/Name&gt; &lt;Levels Count='1'&gt; &lt;Level ID='1' Geometry='1'&gt; // maybe more than one &lt;Name&gt;&lt;![CDATA[Radisson]]&gt;&lt;/Name&gt; &lt;/Level&gt; &lt;/Levels&gt; &lt;/Hall&gt; &lt;Hall ID='3'&gt; &lt;Name&gt;&lt;![CDATA[Test 2]]&gt;&lt;/Name&gt; &lt;Levels Count='0'&gt;&lt;/Levels&gt; &lt;/Hall&gt; &lt;Hall ID='2'&gt; &lt;Name&gt;&lt;![CDATA[тест]]&gt;&lt;/Name&gt; &lt;Levels Count='1'&gt; &lt;Level ID='4' Geometry='2'&gt; &lt;Name&gt;&lt;![CDATA[ттт]]&gt;&lt;/Name&gt; &lt;/Level&gt; &lt;/Levels&gt; &lt;/Hall&gt; &lt;/Halls&gt; &lt;/Theatre&gt; &lt;/Theatres&gt; &lt;/Data&gt; &lt;/XML&gt; </code></pre> <p>And, I have two classes: <code>BasePlace</code> and <code>HallPlan</code> (relation as one-to-many) </p> <p><code>BasePlace</code>: <code>OID, Name, Address</code><br> <code>HallPlan</code>: <code>OID, BasePlaceId, HallId, LevelId</code> </p> <p>For example above the results must be: </p> <pre><code>BasePlace table: OID Name Address 1 PlaceName HallPlan table: OID BasePlaceId, HallId, LevelId 1 1 1 1 2 1 2 4 3 1 3 null </code></pre> <p>This query return fills only <code>BasePlace</code> object:</p> <pre><code>var places = from element in XDocument.Parse(xml).Descendants("Theatre") select new BasePlace { OIDPremiera = (int) element.Attribute("ID"), Name = (string) element.Element("Name"), Address = (string) element.Element("Address"), }; </code></pre> <p>How to fill <code>HallPlan</code> properly( with all fields and relation to <code>BasePlace</code>)?

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.
