AvalonDock - How to disable autohide capability for all anchorables

I'm hoping to remove the "AutoHide" capability from my usage of AvalonDock. I modeled my solution after this example here: http://lostindetails.com/blog/post/AvalonDock-2.0-with-MVVM
My current thought process is that if I can remove the option from both the tab (the symbol next to the "closing X") and the context menu, users won't be able to perform a hide operation. If there is another way to accomplish the removal of the hide operation, that would work as well.
Removing Hide From Tab and Context Menu
In the example, he is able to set the CanClose property on a LayoutItem, thus affecting any item that is displayed due to being inside the DocumentsSource. I would like to do the same thing, but for CanHide and CanAutoHide and have it affect Anchorables inside my AnchorablesSource.
Edit: I have added the line:
<Setter Property="dockctrl:LayoutAnchorableItem.CanHide" Value="False" />
which now gets me half way there. This line removes the hide ability, however it does not remove the "AutoHide" pin symbol (or the context menu option). I know the CanAutoHide property does exist, I'm just not sure how to set it. Here are the relevant docs from Xceed
Current Solution
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<dock:DockingManager x:Name="AvalonDockDockingManager" Grid.Row="1"
AllowMixedOrientation="True"
DataContext="{Binding DockManagerViewModel}"
DocumentsSource="{Binding Documents}"
AnchorablesSource="{Binding Anchorables}" >
<dock:DockingManager.Resources>
</dock:DockingManager.Resources>
<dock:DockingManager.LayoutItemContainerStyle>
<Style TargetType="{x:Type dockctrl:LayoutItem}" >
<Setter Property="Title" Value="{Binding Model.Title}" />
<Setter Property="CloseCommand" Value="{Binding Model.CloseCommand}" />
<Setter Property="CanClose" Value="{Binding Model.CanClose}" />
<Setter Property="dockctrl:LayoutAnchorableItem.CanHide" Value="False" />
</Style>
</dock:DockingManager.LayoutItemContainerStyle>
<dock:DockingManager.AnchorablePaneControlStyle>
<Style TargetType="{x:Type dockctrl:LayoutAnchorableItem}" >
<Setter Property="CanHide" Value="False" />
</Style>
</dock:DockingManager.AnchorablePaneControlStyle>
</dock:DockingManager>
</Grid>

You will have to re-style some elements of AvalonDock to get rid of the AutoHide pin. Below is a sample XAML of the AchorablePaneTitle style taken from the Generic.xaml.
As alternative solution: You can also let the Pin dissappear by setting CanAutoHide="False" and CanHide="False" in this sample application.
The changed XAML looks like this
<avalonDock:LayoutAnchorable x:Name="WinFormsWindow"
ContentId="WinFormsWindow"
Title="WinForms Window"
ToolTip="My WinForms Tool"
CanAutoHide="False"
CanHide="False"
CanClose="False" >
<winformsIntegration:WindowsFormsHost x:Name="winFormsHost" Background="White"/>
</avalonDock:LayoutAnchorable>
This is the screenshot taken from the linked sample application above. Note the missing pin on the Winforms Window.
Override the AnchorablePaneTitle style to get rid of the pin defined in PART_AutoHidePin (eg.: Set Visibility = "Collapsed" on it).

WPF combobox prevent selection update

I've got a ComboBox that looks like this:
I don't want the value of ... to change when one of the items is selected.
I've tried a ton of different solutions - various bindings on SelectedIndex, SelectedValue, SelectionChanged, playing with IsEditable, IsReadonly, IsHitTestVisible, making ... an actual item, making it placeholder text, etc, etc, etc.
Every time I select an item, the ... updates with the child value. I want it to stay the same.
How can I prevent the combobox from automatically updating the text on selection, but still have it able to select a choice?
If it helps, here's the custom template for that image:
<ResourceDictionary

...and its corresponding XAML:

templates:ComboBoxAHelper.RightAlignPopup="True"

HorizontalAlignment="Right"
IsReadOnly="True"
IsEditable="False"

>
<ComboBoxItem>
<TextBlock Style="{StaticResource ComboBoxAItem}">Close</TextBlock>
</ComboBoxItem>
<ComboBoxItem>
<TextBlock Style="{StaticResource ComboBoxAItem}">Delete</TextBlock>
</ComboBoxItem>
</ComboBox>

The trick was to remove
Content="{TemplateBinding SelectionBoxItem}"
from the template (both in general and also the code posted in the question).

WPF EventTrigger not always firing

I have a WPF TreeView that I customized visually looking like this:
I defined an EventTrigger to react on clicks:
<TreeView>

</TreeView>
The problem is that clicking on the root element "Ausführungsvorschrift" only expands the tree but the event is not fired. It fires when clicking on sub elements though and it fires when clicking inside the border. But the header does not fire anything.

Try to add triggers for the Expanded and Collapsed events to the Expander element in the template:
<Expander Name="Exp" IsExpanded="{TemplateBinding TreeViewItem.IsExpanded}">
<i:Interaction.Triggers>
<i:EventTrigger EventName="Expanded">
<i:InvokeCommandAction Command="{Binding DataContext.OpenPartListCommand, RelativeSource={RelativeSource AncestorType=TreeView}}"
CommandParameter="{Binding RelativeSource={RelativeSource AncestorType=TreeViewItem}}" />
</i:EventTrigger>
<i:EventTrigger EventName="Collapsed">
<i:InvokeCommandAction Command="{Binding DataContext.OpenPartListCommand, RelativeSource={RelativeSource AncestorType=TreeView}}"
CommandParameter="{Binding RelativeSource={RelativeSource AncestorType=TreeViewItem}}" />
</i:EventTrigger>
</i:Interaction.Triggers>
<Expander.Header>
<ContentPresenter ContentSource="Header" />
</Expander.Header>
<ItemsPresenter />
</Expander>

WPF tooltip arrow placement

I need a little guidance. I am trying to create your own ToolTip with an arrow. I ran into a problem. If the ToolTip too close to the edge of the screen, so of course change the tooltip positions, but no longer for themselves arrow.

Binding ContextMenu DataContext works with TextBlock but not with TextBox

I got this in my view, I need to be able to edit the name of the Skeleton items in the TreeView via right-click -> context menu -> rename. There is a slight problem:
When I use TextBlock it works fine (TextBlock is not editable) but the binding shuts down when I use TextBox. I tried several bindings and ancestor types, to no avail. Not sure if I should switch to TextBox at all.
