    <p>In WPF app I have a ListView which is connected with ObservableCollection <code> ShQuCollection</code> through databinding:</p> <pre><code>&lt;ListView Name="ShSelList" ItemsSource="{Binding Source={StaticResource myDataSource},Path=ShQuCollection}" SelectionChanged="ShSelList_SelectionChanged"&gt; &lt;ListView.View&gt; &lt;GridView&gt; &lt;GridViewColumn Header="Code" DisplayMemberBinding="{Binding StrCode}"/&gt; &lt;GridViewColumn Header="Date" DisplayMemberBinding="{Binding Date}"/&gt; &lt;GridViewColumn Header="Time" DisplayMemberBinding="{Binding Time}"/&gt; &lt;/GridView&gt; &lt;/ListView.View&gt; &lt;/ListView&gt; </code></pre> <p>From inside ListView SelectionChanged event handler I need to call a method and pass to it a string parameter, taking it from one of the field of the selected row of the ObservableCollection <code> ShQuCollection</code>.</p> <p>How I could reference the ObservableCollection from inside ListView SelectionChanged event handler?</p> <pre><code>private void ShSelList_SelectionChanged(object sender, SelectionChangedEventArgs e) { ...????? } </code></pre> <p><strong>Edited (added):</strong></p> <p>My ObservableCollection is in code-behind file of another window and I use <code>Window.Resources</code> declaration to reach it.</p> <pre><code>&lt;Window.Resources&gt; &lt;c:ShWindow x:Key="myDataSource"/&gt; &lt;/Window.Resources&gt; </code></pre> <p>And ObservableCollection looks like:</p> <pre><code> ObservableCollection&lt;ShsQu&gt; _ShQuCollection = new ObservableCollection&lt;ShsQu&gt;(); public ObservableCollection&lt;ShsQu&gt; ShQuCollection { get { return _ShQuCollection; } } public class ShsQu { public string StrCode { get; set; } public string Date { get; set; } public string Time { get; set; } } </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.
