    <p>I have an object that can't inherit DependencyObject OR use NotifyPropertyChanged, and I've binded it to quite a few controls, so when the properties change, I don't want to go to each control and change it's value on the code, so I'm thinking there must be a way to tell the XAML to "Rebind" all that it's bound to with one or two lines of code, instead of going:</p> <pre><code>label1.Content = myObject.DontNotifyThis; label2.Content = myObject.DontNotifyThisEither; label3.Content = myObject.DontEvenThinkOfNotifyingThis; label4.Content = myObject.NotSoFastPal; </code></pre> <p>So on, so forth...</p> <p>This is an oversimplified example:</p> <p>XAML:</p> <pre><code>&lt;Window x:Class="StackOverflowTests.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" x:Name="window1" Height="300" Width="300" Loaded="window1_Loaded"&gt; &lt;Grid x:Name="gridMain"&gt; &lt;Grid.RowDefinitions&gt; &lt;RowDefinition Height="Auto" /&gt; &lt;RowDefinition Height="Auto" /&gt; &lt;RowDefinition Height="Auto" /&gt; &lt;/Grid.RowDefinitions&gt; &lt;Label Grid.Row="0" Content="{Binding Status}" ContentStringFormat="Today's weather: {0}" /&gt; &lt;Label Grid.Row="2" Content="{Binding Temperature}" ContentStringFormat="Today's temperature: {0}" /&gt; &lt;Label Grid.Row="1" Content="{Binding Humidity}" ContentStringFormat="Today's humidity: {0}" /&gt; &lt;/Grid&gt; &lt;/Window&gt; </code></pre> <p>C#:</p> <pre><code>using System.Windows; namespace StackOverflowTests { /// &lt;summary&gt; /// Interaction logic for Window1.xaml /// &lt;/summary&gt; public partial class Window1 : Window { Weather weather = new Weather("Cloudy", "60F", "25%"); public Window1() { InitializeComponent(); this.DataContext = weather; } private void window1_Loaded(object sender, RoutedEventArgs e) { weather.Status = "Sunny"; weather.Temperature = "80F"; weather.Humidity = "3%"; } } class Weather { public string Status { get; set; } public string Temperature { get; set; } public string Humidity { get; set; } public Weather(string status, string temperature, string humidity) { this.Status = status; this.Temperature = temperature; this.Humidity = humidity; } } } </code></pre> <p>I found a way to do it, but it's not elegant at all, and unfortunatelly, I can't just set the DataContext to a new instance of weather, it needs to be the SAME reference (that's why I set it to null so it changes):</p> <pre><code>private void window1_Loaded(object sender, RoutedEventArgs e) { weather.Status = "Sunny"; weather.Temperature = "80F"; weather.Humidity = "3%"; // bad way to do it Weather w = (Weather)this.DataContext; this.DataContext = null; this.DataContext = w; } </code></pre> <p>Thanks in advance!</p>

    2. COWe're using Undo/Redo on our app, INotifyPropertyChanging serializes the previous state of the Object, INotifyPropertyChanged enables saving the object into a new XmlSerialized file. However, these specific proprerties that I need to change do not alter the save state of the object (doesn't change font, color, background, border) or anything that the user would want to save. If I NotifyPropertyChanging / Changed with those properties, the system will think the object was changed, but to the user, it wasn't. This is why I can't use that.

    3. COUnderstood, but that sounds like a flawed design to me. You'd be better off with INPC as a generic property changed notification, and then another mechanism to track state changes that you care about undoing/redoing. May be too late to change your design though, so point taken.

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).
