    <p>I'm tring to insert an hyperlink within a <code>DataGrid</code> and find a method in order to implement the <code>RequestNavigate</code> behaviour using the MVVM pattern.</p> <p>I've tried a lot of solutions up until now, but none of them works. Could you help me, please?</p> <p>This is my xaml code:</p> <pre><code>&lt;dgWPFCtrl:ExtDataGridTemplateColumn Header="Link to XXX" Width="*"&gt; &lt;dgWPFCtrl:ExtDataGridTemplateColumn.CellTemplate&gt; &lt;DataTemplate&gt; &lt;TextBlock &gt; &lt;Hyperlink NavigateUri="{Binding Path=ID_HTTP_LINK}" &gt; &lt;TextBlock Text="{Binding Path=ID_HTTP_LINK}"/&gt; &lt;i:Interaction.Triggers&gt; &lt;i:EventTrigger EventName="RequestNavigate"&gt; &lt;WPFCtrl:EventToCommand PassEventArgsToCommand="True" Command="{Binding Path=OpenLinkCommand}" /&gt; &lt;/i:EventTrigger&gt; &lt;/i:Interaction.Triggers&gt; &lt;/Hyperlink&gt; &lt;/TextBlock&gt; &lt;/DataTemplate&gt; &lt;/dgWPFCtrl:ExtDataGridTemplateColumn.CellTemplate&gt; &lt;/dgWPFCtrl:ExtDataGridTemplateColumn&gt; </code></pre> <p>and following the relative <code>ICommand</code> development:</p> <pre class="lang-cs prettyprint-override"><code>//Command for open link RelayCommand _openLinkCommand; public ICommand OpenLinkCommand { get { if (_openLinkCommand == null) _openLinkCommand = new RelayCommand(param =&gt; { //Command Body ... }); return _openLinkCommand; } } </code></pre> <p>Where I'm wrong? Unexpectedly, the <code>ICommand</code> is never even called!</p> <p>I've tried to use also other kind of event ( such as <code>MouseEnter</code>), but nothing changed!</p> <p>Thanks in advance for your contributions,</p> <p>Deby</p>

Guidance
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.

SQuiL has stopped working due to an internal error.

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