    <p>I'm practicing C# with wpf and I'm trying to use template formatting.<br> At this time, I have a customized combobox bind link this:</p> <pre><code>&lt;ComboBox Height="23" HorizontalAlignment="Left" Margin="177,28,0,0" Name="JoinedFiles_combobox" VerticalAlignment="Top" Width="164" Grid.Column="1" SelectionChanged="JoinedFiles_combobox_SelectionChanged"&gt; &lt;ComboBox.ItemTemplate&gt; &lt;DataTemplate&gt; &lt;Canvas Height="18"&gt; &lt;Image Name="ImageName" Height="16" Width="16" Canvas.Left="1" Canvas.Top="1"/&gt; &lt;TextBlock Text="{Binding Name}" Canvas.Left="26" Canvas.Top="1" Width="120"/&gt; &lt;/Canvas&gt; &lt;DataTemplate.Triggers&gt; &lt;DataTrigger Binding="{Binding PictureID}" Value="0"&gt; &lt;Setter TargetName="ImageName" Property="Source" Value="Resources\0.png"/&gt; &lt;/DataTrigger&gt; &lt;DataTrigger Binding="{Binding PictureID}" Value="1"&gt; &lt;Setter TargetName="ImageName" Property="Source" Value="Resources\1.png"/&gt; &lt;/DataTrigger&gt; &lt;/DataTemplate.Triggers&gt; &lt;/DataTemplate&gt; &lt;/ComboBox.ItemTemplate&gt; &lt;/ComboBox&gt; </code></pre> <p>As I want another combobox like this in another xaml file (another window), I am trying to put this as a template in my <code>app.xaml</code> file. This will prevent the copying of code and simplify things. </p> <p>This is what I wrote in the <code>app.xaml</code> file:</p> <pre><code>&lt;Application.Resources&gt; &lt;ResourceDictionary&gt; &lt;ControlTemplate x:Key="CustomisedComboBox" TargetType="{x:Type ComboBox}"&gt; &lt;ItemTemplate&gt; &lt;DataTemplate&gt; &lt;Canvas Height="18"&gt; &lt;Image Name="ImageName" Height="16" Width="16" Canvas.Left="1" Canvas.Top="1"/&gt; &lt;TextBlock Text="{Binding Name}" Canvas.Left="26" Canvas.Top="1" Width="120"/&gt; &lt;/Canvas&gt; &lt;DataTemplate.Triggers&gt; &lt;DataTrigger Binding="{Binding PictureID}" Value="0"&gt; &lt;Setter TargetName="ImageName" Property="Source" Value="Resources\0.png"/&gt; &lt;/DataTrigger&gt; &lt;DataTrigger Binding="{Binding PictureID}" Value="1"&gt; &lt;Setter TargetName="ImageName" Property="Source" Value="Resources\1.png"/&gt; &lt;/DataTrigger&gt; &lt;/DataTemplate.Triggers&gt; &lt;/DataTemplate&gt; &lt;/ItemTemplate&gt; &lt;/ControlTemplate&gt; &lt;/ResourceDictionary&gt; &lt;/Application.Resources&gt; </code></pre> <p>The problem is that it can't find ItemTemplate in my control template. How can I give it that item template?</p>

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.
