<p>I was trying to change list items appearance in dataTemplate but I had problem with changing a selected item look. I've found this question: <a href="https://stackoverflow.com/questions/146269/change-wpf-datatemplate-for-listbox-item-if-selected">Change WPF DataTemplate for ListBox item if selected</a></p> <p>and i tried to create similar code as in the answer:</p> <pre><code><DataTemplate x:Key="NoteTemplate"> <Border Margin="5" BorderThickness="1" BorderBrush="Transparent" Background="#F3EBC2" CornerRadius="4"> <Grid Margin="3" Width="395" MaxHeight="40"> <Grid.RowDefinitions> <RowDefinition /> <RowDefinition/> </Grid.RowDefinitions> <Grid Row="0" > <Grid.ColumnDefinitions> <ColumnDefinition/> <ColumnDefinition/> </Grid.ColumnDefinitions> <TextBlock Grid.Column="0" FontSize="15" FontFamily="Consolas" FontWeight="Bold" Text="{Binding Path=tytul}"/> <TextBlock Grid.Column="1" FontSize="13" FontFamily="Consolas" FontStyle="Italic" HorizontalAlignment="Right" Text="{Binding Path=data_dodania}"/> </Grid> <TextBlock Grid.Row="1" FontSize="13" FontFamily="Consolas" Text="{Binding Path=tresc}"/> </Grid> </Border> </DataTemplate> <Style TargetType="{x:Type ListBoxItem}" x:Key="ListBoxItem"> <Setter Property="ContentTemplate" Value="{StaticResource NoteTemplate}" /> <Style.Triggers> <Trigger Property="IsSelected" Value="True"> <Setter Property="ContentTemplate" Value="{StaticResource NoteTemplate}" /> </Trigger> </Style.Triggers> </Style> </code></pre> <p>(I put the same template in trigger just to check if it works)</p> <pre><code><ListBox Name="listBoxNotatki" Margin="10" ItemContainerStyle="{StaticResource ListBoxItem}" Background="Beige" BorderBrush="Orange" BorderThickness="3"/> </code></pre> <p>But then i got this error:</p> <p>"Unable to cast object of type 'MS.Internal.NamedObject' to type 'System.Windows.DataTemplate'."</p> <p>When I change StaticResource to DynamicResorce i get rid of this error but then the trigger in my style doesn't work (Selected item looks just like at the beginning). </p>

Guidance

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.
