    <p>I'm working on a WPF application and i have a little problem.</p> <p>I have 1 ToggleButton and 1 TextBox. When i click on the ToggleButton, the TextBox apears and gets focus. This is good. But now i want that when i click on another textbox or just somewhere else, that the textbox loses his focus and disapears. I tried this with Differnet triggers and setters, but can't get it to work.</p> <p>My code now:</p> <pre><code> &lt;ToggleButton x:Name="SearchButton" Width="100" Height="100" BorderThickness="0" Margin="580,0,0,0" Template="{DynamicResource ButtonBaseControlTemplate1}" Panel.ZIndex="1"&gt; &lt;ToggleButton.Style&gt; &lt;Style TargetType="ToggleButton"&gt; &lt;Style.Triggers&gt; &lt;MultiDataTrigger&gt; &lt;MultiDataTrigger.Conditions&gt; &lt;Condition Binding="{Binding IsChecked, ElementName=SearchButton}" Value="True" /&gt; &lt;Condition Binding="{Binding Visibility, ElementName=SearchBox}" Value="Visible"/&gt; &lt;/MultiDataTrigger.Conditions&gt; &lt;Setter Property="FocusManager.FocusedElement" Value="{Binding ElementName=SearchBox}" /&gt; &lt;/MultiDataTrigger&gt; &lt;/Style.Triggers&gt; &lt;/Style&gt; &lt;/ToggleButton.Style&gt; &lt;/ToggleButton&gt;&lt;TextBox x:Name="SearchBox" Margin="100,33,0,34" Visibility="{Binding IsChecked, ElementName=SearchButton, Converter={StaticResource BoolVisibilityConverter}}" Opacity="0" FontSize="24" FontFamily="Arial" Background="{x:Null}" Foreground="#FF7F7F7F" BorderThickness="0"&gt; &lt;TextBox.Style&gt; &lt;Style TargetType="TextBox"&gt; &lt;Style.Triggers&gt; &lt;Trigger Property="TextBox.IsFocused" Value="False"&gt; &lt;Setter Property="ToggleButton.IsChecked" Value="False" TargetName="SearchButton" /&gt; &lt;/Trigger&gt; &lt;/Style.Triggers&gt; &lt;/Style&gt; &lt;/TextBox.Style&gt; &lt;/TextBox&gt; </code></pre>

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).
