    <p><a href="https://stackoverflow.com/questions/13567794/how-to-disallow-the-selection-of-an-interactive-listbox-item/13588128#13588128">This guy wanted to do something alike with a ListBox</a>. I believe the solution can be adapted to work with the DataGrid as well.</p> <p><strong>EDIT</strong></p> <pre><code>public static class DataGridRowEx { public static bool GetCanSelect(DependencyObject obj) { return (bool)obj.GetValue(CanSelectProperty); } public static void SetCanSelect(DependencyObject obj, bool value) { obj.SetValue(CanSelectProperty, value); } public static readonly DependencyProperty CanSelectProperty = DependencyProperty.RegisterAttached("CanSelect", typeof(bool), typeof(DataGridRowEx), new UIPropertyMetadata(true, OnCanSelectChanged)); private static void OnCanSelectChanged(DependencyObject sender, DependencyPropertyChangedEventArgs args) { var item = sender as DataGridRow; if (item == null) return; if ((bool)args.NewValue) { item.Selected -= RowSelected; } else { item.Selected += RowSelected; item.IsSelected = false; } } private static void RowSelected(object sender, RoutedEventArgs e) { var item = sender as DataGridRow; if (item == null) return; item.Dispatcher.BeginInvoke((Action)(()=&gt; item.IsSelected = false)); } } </code></pre> <p>To test it:</p> <pre><code>public class ViewModel : INotifyPropertyChanged { #region INotifyPropertyChanged values public event PropertyChangedEventHandler PropertyChanged; protected void OnPropertyChanged(string propertyName) { if (this.PropertyChanged != null) { this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } } #endregion public List&lt;Dummy&gt; Elements { get; set; } public ViewModel() { this.Elements = new List&lt;Dummy&gt;(){ new Dummy() { CanSelect =true, MyProperty = "Element1"}, new Dummy() { CanSelect =false, MyProperty = "Element2"}, new Dummy() { CanSelect =true, MyProperty = "Element3"}, new Dummy() { CanSelect =false, MyProperty = "Element4"}, new Dummy() { CanSelect =true, MyProperty = "Element5"}, new Dummy() { CanSelect =true, MyProperty = "Element6"}, new Dummy() { CanSelect =true, MyProperty = "Element7"}, new Dummy() { CanSelect =true, MyProperty = "Element8"}, new Dummy() { CanSelect =false, MyProperty = "Element9"}, }; } } public class Dummy { public bool CanSelect { get; set; } public string MyProperty { get; set; } public override string ToString() { return this.MyProperty; } } &lt;Window x:Class="WpfApplication1.MainWindow" 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:i="http://schemas.microsoft.com/expression/2010/interactivity" xmlns:local="clr-namespace:WpfApplication1" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" Title="MainWindow" Width="525" Height="350" mc:Ignorable="d"&gt; &lt;Window.Resources&gt; &lt;Style x:Key="DataGridRowStyle" TargetType="{x:Type DataGridRow}"&gt; &lt;Setter Property="local:DataGridRowEx.CanSelect" Value="{Binding CanSelect}" /&gt; &lt;/Style&gt; &lt;/Window.Resources&gt; &lt;Window.DataContext&gt; &lt;local:ViewModel /&gt; &lt;/Window.DataContext&gt; &lt;Grid x:Name="LayoutRoot"&gt; &lt;DataGrid ItemsSource="{Binding Elements}" RowStyle="{DynamicResource DataGridRowStyle}" SelectionUnit="FullRow" /&gt; &lt;/Grid&gt; &lt;/Window&gt; </code></pre> <p>It works with multiselection, even when pressing shift. The only significant difference from the solution for the ListBoxItem was that the unselection had to be queued using Dispatcher.BeginInvoke, not sure why. The only caveat with this approach is that trying to select an unselectable item unselects the current selected one if the DataGrid has single selection, or unselects all, if the DataGrid has extended selection.</p>

    1. COHmmm, I've tried it with my code but to no avail. However in the test project it works, so thanks. I'll try to integrate it with my code again.

    2. COI need to work out the logic for my specific application, but this has helped. the item.Dispatcher.BeginInvoke((Action)(()=> item.IsSelected = false)); lines were what I needed, thank you.

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.

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