    <p>I'm assuming your datagrid is bound to an IEnumerable, maybe a List&lt;>? Have you tried using an ObservableCollection&lt;>? If you are bound to an ObservableCollection, it will let the UI know when the collection has changed.</p> <pre><code>&lt;UserControl x:Class="SilverlightApplication1.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:local="clr-namespace:SilverlightApplication1" xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="400"&gt; &lt;UserControl.DataContext&gt; &lt;local:MainPage_ViewModel/&gt; &lt;/UserControl.DataContext&gt; &lt;StackPanel&gt; &lt;data:DataGrid ItemsSource="{Binding MyCollection}"&gt; &lt;/data:DataGrid&gt; &lt;/StackPanel&gt; </code></pre> <p></p> <pre><code>public class MainPage_ViewModel : INotifyPropertyChanged { public ObservableCollection&lt;object&gt; MyCollection { get { return myCollection; } set { if (myCollection != value) { myCollection = value; OnPropertyChanged("MyCollection"); } } } private ObservableCollection&lt;object&gt; myCollection = new ObservableCollection&lt;object&gt;(); public void LoadData() { //execute load method, the assign result to MyCollection } #region INotifyPropertyChanged Members public event PropertyChangedEventHandler PropertyChanged; public void OnPropertyChanged(string propertyName) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } } #endregion } </code></pre>

    1. COIs it just a matter of changing the GetDocumentsQuery() from IEnumerable<> to ObservableCollection<>?? Or is it more involved than this?

    2. COI would need to see you XAML and viewModel to be able to answer this. Your datagrid should have an ItemsSource that is bound to an ObservableCollection<> on your viewModel. When you get the data back from GetDocumentsQuery(), you should assign it to your ObservableCollection on your viewModel. Does that make sense?

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).
