WPF - How to skip a label in tab navigation? - wpf

Question

I have a stackpanel inside a controltemplate inside a itemscontrol inside a stackpanel inside a grid inside a usercontrol (se the xaml below). In the inner stackpanel there is a label (Name="NoComponentChosen") and another stackpanel (Name="ComponentChosen"). The label's visibility is initially collapsed.
The controltemplate has a datatrigger with a binding. When the binding reference has a specific value the label (NoComponentChosen) becomes visible and the stackpanel collapses.
I would like to skip the label/stackpanel when I am tabbing trough the user interface. I would also like to still be able tab through the rest of the things in my ChangeRequestView.xaml (listbox and buttons).
Right now - when I tab - the label/stackpanel eventually becomes chosen and is surrounded by a dotted rectangle. That is what I would like to avoid.
This is my ChangeRequestView.xaml:
<UserControl x:Class="MyProgram.View.ChangeRequestView"
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:ListBoxBehavior="clr-namespace:MyProgram.Utility"
mc:Ignorable="d"
d:DesignHeight="500" d:DesignWidth="300">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="50"/>
<RowDefinition Height="35"/>
<RowDefinition Height="45*"/>
<RowDefinition Height="10*"/>
<RowDefinition Height="20*"/>
<RowDefinition Height="35"/>
</Grid.RowDefinitions>
<!--The title of the view-->
<Label Grid.Row="0" Content="Change Requests" FontWeight="Bold" Margin="5,5,5,5" VerticalAlignment="Center" HorizontalAlignment="Center"/>
<!--The component chosen-->
<StackPanel Grid.Row="1" Orientation="Horizontal" Margin="5,0,0,0" IsHitTestVisible="False" Focusable="False">
<ItemsControl>
<ItemsControl.Template>
<ControlTemplate>
<StackPanel>
<StackPanel Name="ComponentChosen" Orientation="Horizontal">
<Label Content="Reference des.: " />
<Label Name="referenceDesignation" Content="{Binding Path=ReferenceDesignation, UpdateSourceTrigger=PropertyChanged}"/>
</StackPanel>
<Label Name="NoComponentChosen" Content="Choose a component" Visibility="Collapsed"/>
</StackPanel>
<ControlTemplate.Triggers>
<DataTrigger Binding="{Binding ReferenceDesignation}" Value="">
<Setter TargetName="ComponentChosen" Property="Visibility" Value="Collapsed"/>
<Setter TargetName="NoComponentChosen" Property="Visibility" Value="Visible"/>
</DataTrigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</ItemsControl.Template>
</ItemsControl>
</StackPanel>
<ListBox Grid.Row="2" ... />
<Button Grid.Row="3" ... />
<Button Grid.Row="4" ... />
</Grid>
</UserControl>
The whole UserControl/ChangeRequestView.xaml is part of my MainWindow - I don't know if that has anything to say. I tab through all of the different views in my MainWindow, and when I get to the ChangeRequestView I would like to skip the label/stackpanel according to which of them isn't collapsed.
This is my MainWindow.xaml:
<Window x:Class="MyProgram.MainWindow"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

<Grid.ColumnDefinitions>
<ColumnDefinition Width="209*"/>
<ColumnDefinition Width="558*"/>
<ColumnDefinition Width="250*"/>
</Grid.ColumnDefinitions>
<Menu IsMainMenu="True" Name="Menu1" VerticalAlignment="Top" Grid.Row="0" Grid.ColumnSpan="3">
<MenuItem Header="_File">
<MenuItem Header="_Save changed change requests for current reference designation"
InputGestureText="Ctrl+S" Command="{Binding Path=HotKeysSaveChangeRequestUpdateCmd}"/>
<MenuItem Header="_Upload change requests for current project"
InputGestureText="Ctrl+U" Command="{Binding Path=HotKeysUploadCmd}"/>
<MenuItem Header="_Exit" ToolTip="Exit this program"
InputGestureText="CTRL+X" Command="{Binding Path=ShutDownCmd}"/>
</MenuItem>
</Menu>

I apologize for the long xaml-files, but I'm thinking the more information I provide to you the easier it will be for you to help me solve this tabbing issue.
Do you have any ideas of how to skip the label "NoComponentChosen"/the stackpanel "ComponentChosen" when I tab through the user interface?

Try KeyboardNavigation.TabNavigation Attached Property with KeyboardNavigationMode.None on the container with the elements you want to skip.
KeyboardNavigation.TabNavigation="None"
