    copied!<p>So...having become the proud owner of a tumbleweed badge, I've got back on to this to try &amp; find a way around it. ;-)</p> <p>I'm not sure I like the solution so I'm still very much open to any better approaches.</p> <p>Basically, what I ended up doing is remember what ListBoxItem was last clicked on &amp; then make sure that gets added to the selected items before a drag. This also meant looking at how far the mouse moves before starting a drag - because clicking on a selected item to unselect it could sometimes result in it getting selected again if mouse bounce started a little drag operation.</p> <p>Finally, I added some hot tracking to the listbox items so, if you mouse down on a selected item it'll get unselected but you still get some feedback to indicate that it will get included in the drag operation.</p> <pre><code>private void HandleLeftButtonDown(object sender, MouseButtonEventArgs e) { var source = (FrameworkElement)sender; var hitItem = source.InputHitTest(e.GetPosition(source)) as FrameworkElement; hitListBoxItem = hitItem.FindVisualParent&lt;ListBoxItem&gt;(); origPos = e.GetPosition(null); } private void HandleLeftButtonUp(object sender, MouseButtonEventArgs e) { hitListBoxItem = null; } private void HandleMouseMove(object sender, MouseEventArgs e) { if (ShouldStartDrag(e)) { hitListBoxItem.IsSelected = true; var sourceItems = (FrameworkElement)sender; var viewModel = (WindowViewModel)DataContext; DragDrop.DoDragDrop(sourceItems, viewModel, DragDropEffects.Move); hitListBoxItem = null; } } private bool ShouldStartDrag(MouseEventArgs e) { if (hitListBoxItem == null) return false; var curPos = e.GetPosition(null); return Math.Abs(curPos.Y-origPos.Y) &gt; SystemParameters.MinimumVerticalDragDistance || Math.Abs(curPos.X-origPos.X) &gt; SystemParameters.MinimumHorizontalDragDistance; } </code></pre> <p>XAML changes to include hot tracking...</p> <pre><code>&lt;Style TargetType="ListBoxItem"&gt; &lt;Setter Property="Margin" Value="1"/&gt; &lt;Setter Property="Template"&gt; &lt;Setter.Value&gt; &lt;ControlTemplate TargetType="{x:Type ListBoxItem}"&gt; &lt;Grid&gt; &lt;Border Background="{TemplateBinding Background}" /&gt; &lt;Border Background="#BEFFFFFF" Margin="1"&gt; &lt;Grid&gt; &lt;Grid.RowDefinitions&gt; &lt;RowDefinition /&gt;&lt;RowDefinition /&gt; &lt;/Grid.RowDefinitions&gt; &lt;Border Margin="1" Grid.Row="0" Background="#57FFFFFF" /&gt; &lt;/Grid&gt; &lt;/Border&gt; &lt;ContentPresenter Margin="8,5" /&gt; &lt;/Grid&gt; &lt;ControlTemplate.Triggers&gt; &lt;Trigger Property="IsSelected" Value="True"&gt; &lt;Setter Property="Background" Value="PowderBlue" /&gt; &lt;/Trigger&gt; &lt;MultiTrigger&gt; &lt;MultiTrigger.Conditions&gt; &lt;Condition Property="IsMouseOver" Value="True" /&gt; &lt;Condition Property="IsSelected" Value="False"/&gt; &lt;/MultiTrigger.Conditions&gt; &lt;Setter Property="Background" Value="#5FB0E0E6" /&gt; &lt;/MultiTrigger&gt; &lt;/ControlTemplate.Triggers&gt; &lt;/ControlTemplate&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;/Style&gt; </code></pre>
