    <p>I apologize if this is an easy question, but I have been trying to get this to work all day and I can't seem to figure something out that is fairly obvious probably.</p> <p>I have a user control with a custom dependency property "Flipped".</p> <p>In my resource I have a Style with two triggers defined, that set the template of the control to two different values depending on if 'Flipped' is true of false.</p> <p>Now, what syntax do I use to apply the style to this user control I am creating?</p> <p>Putting <code>Style="{StaticResource EventStyle}"</code> in the header of the <code>UserControl</code> won't work.</p> <p>Here is what I have so far : </p> <pre><code>&lt;UserControl x:Class="XDPClient.Controls.EventMarkerControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:Controls="clr-namespace:XDPClient.Controls" mc:Ignorable="d" d:DesignHeight="513" d:DesignWidth="695"&gt; &lt;UserControl.Resources&gt; &lt;!-- Draw the user control right side up with this template --&gt; &lt;ControlTemplate x:Key="Up" TargetType="{x:Type Controls:EventMarkerControl}"&gt; &lt;Grid&gt; &lt;!-- Outline grid --&gt; &lt;Path Stretch="Fill" Fill="#FFFFFFFF" Stroke="#FF6800FF" StrokeThickness="3" StrokeStartLineCap="Flat" StrokeEndLineCap="Flat" StrokeLineJoin="Miter" StrokeMiterLimit="4" Name="rect2985" RenderTransformOrigin="0,0"&gt; &lt;Path.Data&gt; &lt;PathGeometry FillRule="Nonzero" Figures="M 0,250 L 0,50 L 150,50 L 200,-0.96 L 250,50 L 400,50 L 400,250 L 0,250z" /&gt; &lt;/Path.Data&gt; &lt;/Path&gt; &lt;!-- Placement of the content --&gt; &lt;Grid&gt; &lt;Grid.RowDefinitions&gt; &lt;RowDefinition Height="1*" /&gt; &lt;RowDefinition Height="4*" /&gt; &lt;/Grid.RowDefinitions&gt; &lt;Grid Grid.Row="1" Margin="3"&gt; &lt;ContentPresenter Grid.Row="1" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/&gt; &lt;/Grid&gt; &lt;/Grid&gt; &lt;Grid.BitmapEffect&gt; &lt;DropShadowBitmapEffect /&gt; &lt;/Grid.BitmapEffect&gt; &lt;/Grid&gt; &lt;/ControlTemplate&gt; &lt;!-- Draw the user control flipped with this template --&gt; &lt;ControlTemplate x:Key="Down" TargetType="{x:Type Controls:EventMarkerControl}"&gt; &lt;Grid&gt; &lt;!-- Outline grid --&gt; &lt;Path Stretch="Fill" Fill="#FFFFFFFF" Stroke="#FF6800FF" StrokeThickness="3" StrokeStartLineCap="Flat" StrokeEndLineCap="Flat" StrokeLineJoin="Miter" StrokeMiterLimit="4" Name="rect2985" RenderTransformOrigin="0,0"&gt; &lt;Path.Data&gt; &lt;PathGeometry FillRule="Nonzero" Figures="M 0,250 L 0,50 L 150,50 L 200,-0.96 L 250,50 L 400,50 L 400,250 L 0,250z" /&gt; &lt;/Path.Data&gt; &lt;Path.RenderTransform&gt; &lt;ScaleTransform ScaleX="-1" /&gt; &lt;/Path.RenderTransform&gt; &lt;/Path&gt; &lt;!-- Placement of the content --&gt; &lt;Grid&gt; &lt;Grid.RowDefinitions&gt; &lt;RowDefinition Height="1*" /&gt; &lt;RowDefinition Height="4*" /&gt; &lt;/Grid.RowDefinitions&gt; &lt;Grid Grid.Row="1" Margin="3"&gt; &lt;ContentPresenter Grid.Row="1" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/&gt; &lt;/Grid&gt; &lt;/Grid&gt; &lt;Grid.BitmapEffect&gt; &lt;DropShadowBitmapEffect /&gt; &lt;/Grid.BitmapEffect&gt; &lt;/Grid&gt; &lt;/ControlTemplate&gt; &lt;Style x:Key="EventStyle" TargetType="{x:Type Controls:EventMarkerControl}"&gt; &lt;Style.Triggers&gt; &lt;Trigger Property="Flipped" Value="false"&gt; &lt;Setter Property="Template" Value="{StaticResource Up}" /&gt; &lt;/Trigger&gt; &lt;Trigger Property="Flipped" Value="true"&gt; &lt;Setter Property="Template" Value="{StaticResource Down}" /&gt; &lt;/Trigger&gt; &lt;/Style.Triggers&gt; &lt;/Style&gt; &lt;/UserControl.Resources&gt; </code></pre> <p></p>

    1. COPutting this in the body of the user control will cause the ide to crash (recursion I assume) <Grid> <Controls:EventMarkerControl Style="{StaticResource EventStyle}" /> </Grid>

    3. CO@DJ That _is_ my entire UserControl xaml. There is of course a dependency prop defined in code behind called "Flipped" that is a bool.

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).
