    <p>So I'm trying to wrap my head around MVVM and I'm finding that I have more questions than answers. The tutorials don't go far enough for me when it comes to the next step...</p> <p>Basically I want a list of items and then a way to get the detail of each item.</p> <p>Below is the examples that I've found online and they work great for displaying the list, but I need to know how I can use my VM to get the detail of this item.</p> <pre><code>private IList&lt;item&gt; m_items; private IList&lt;item&gt; m_Item; private IList&lt;item&gt; getItemDetail(Int32 iId) { var myItem = from i in items where i.iId == iId select i; m_Item = new List&lt;item&gt;(); foreach (var item in myItem) { m_Item.Add(item); } return m_Item; } public myViewModel() { m_items = new List&lt;item&gt; { new item(1, "test,), new item(2, "test2"), new item(3, "test1") }; m_Item = new List&lt;item&gt;(); m_Item = getItemDetail(iId); } </code></pre> <p><strong>Update:</strong></p> <p>I updated my View Model code above. I think what I've done is I have added another List where when the user navigates to a detail page the view model gets called with the specific ID which then populates the detail List. I probably don't need a list here but I wanted to try to keep it consistent with the main page code.</p> <p>In my detail page I'm setting up the VM this way:</p> <pre><code> itemViewModel VM = new itemViewModel((Int32)navigationParameter); DataContext = VM; </code></pre> <p>When I break on the VM variable I see my 2 lists. However, my binding doesn't work on the XAML. If I need to post some sample XAML let me know. I can do that but I'm hoping there is something I'm missing here. </p> <p>I'm trying to learn MVVM and I want to do things right. So instead of continuing down a wrong path I would really like to know the "right" way of doing things. So if you see errors, please let me know.</p> <p>Thanks!</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.
