    <p>I have a program where I am reading a .csv file with 2 columns, and my model has 2 properties. I take instances of this model as the file is read and then add them to my ObvervableCollection.</p> <p>Here is what it looks like:</p> <pre><code>// My data field private ObservableCollection&lt;Model&gt; _internalFile = new ObservableCollection&lt;Model&gt;(); // My data accessor/setter public ObservableCollection&lt;Model&gt; InternalFile { get { return _internalFile; } set { _internalFile = value; } } Model x = new Model(); while (fileReader.Peek() != -1) { // words = read the line, split the line, make a list of columns var words = fileReader.ReadLine().Split(',').ToList(); if (words[0] != "Name") { x.asWord = words[0]; x.asNumber = int.Parse(words[1]); InternalFile.Add(x); // InternalFile is a collection of 'Model' objects. // So created 'Model' placeholder , x, and pile each instance of x // in the collection to be displayed. } } </code></pre> <p>My XAML looks like this </p> <pre><code>&lt;Window x:Class="WpfMVVP.WindowView" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfMVVP" Title="Window View" Height="350" Width="525" Background="White"&gt; &lt;Grid&gt; &lt;Grid.RowDefinitions&gt; &lt;RowDefinition Height="Auto"/&gt; &lt;RowDefinition Height="Auto"/&gt; &lt;/Grid.RowDefinitions&gt; &lt;DataGrid Grid.Row="0" AutoGenerateColumns="False" CanUserReorderColumns="False" ItemsSource="{Binding Path=InternalFile}"&gt; &lt;DataGrid.Columns&gt; &lt;DataGridTextColumn Header="As Word" IsReadOnly="True" Width="Auto" Binding="{Binding asWord}" /&gt; &lt;DataGridTextColumn Header="As Number" IsReadOnly="True" Width="Auto" Binding="{Binding asNumber}" /&gt; &lt;/DataGrid.Columns&gt; &lt;/DataGrid&gt; &lt;Label Grid.Row="1" Content="{Binding Status}" /&gt; &lt;/Grid&gt; </code></pre> <p></p> <p>In the window displayed, I am seeing the columns populate but all the rows are the last row that was read before end of file. It is as if the ObservableCollection is overwriting its previous elements with a new value. I don't know why it's behaving like that.</p> <p><img src="https://i.stack.imgur.com/2B8hO.png" alt="Application Window"></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.
