WPF Listbox items with name on mouseover or active

I've tried several different solutions to this, but can't land on one that meets all of my needs.
We have an observable collection of objects that each have a status and a name. It's a sort of task-list of running items. To display this list in WPF, we have some code that represents each item as an ellipse with some colors and animations.
The problem is that we want to display the name of the item as a 'popup' both on mouseover, or when the task is in a given state.
Attempt #1
My first attempt implemented this as a Datatemplate (to be used as an ItemTemplate) with an actual WPF Popup. I implemented two datatriggers - one for mouseover and one for task state. I positioned the popup based on my ellipse and everything was great. However, moving the window or switching to a different window left the popup on top of everything.
Attempt #2
Instead of using the popup I used a textbox in a canvas. This works great until the Datatemplate is used in the Listbox. The item host (stackpanel) ends up clipping the string.
Here's example code:
<DataTemplate x:Key="EllipseTemplate">
<Grid Height="40" Width="40">
<Canvas Name="PopupCanvas" HorizontalAlignment="Center" Width="500">
<TextBlock Name="PopupName"
Width="{Binding ElementName=PopupCanvas, Path=ActualWidth}"
Text="{Binding}"
Background="Transparent"
FontSize="16" HorizontalAlignment="Center" TextAlignment="Center" FontWeight="Bold"
Canvas.Top="-25"
Visibility="Collapsed"
/>
</Canvas>
<Ellipse x:Name="Ellipse" Height="25" Width="25" Margin="0"
HorizontalAlignment="Center" VerticalAlignment="Center"
Fill="Green"
RenderTransformOrigin="0.5, 0.5" StrokeThickness="0.5" Stroke="Black">
</Ellipse>
</Grid>
<DataTemplate.Triggers>
<DataTrigger Binding="{Binding IsMouseOver, RelativeSource={RelativeSource TemplatedParent}}" Value="True">
<Setter TargetName="PopupName" Property="Visibility" Value="Visible" />
</DataTrigger>
</DataTemplate.Triggers>
</DataTemplate>
<Grid Name="Test" Background="LightGoldenrodYellow" ClipToBounds="False" Margin="50">
<ListBox Name="OverlayTest"
Background="CornflowerBlue"
BorderThickness="0"
VerticalAlignment="Center"
Margin="10"
ClipToBounds="False"
ItemTemplate="{StaticResource EllipseTemplate}">
<sys:String>Very long string that will get clipped</sys:String>
<sys:String>Two</sys:String>
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" IsItemsHost="True" Margin="10,50,10,50" ClipToBounds="False"/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
</ListBox>
</Grid>
Attempt #3
I moved my canvas/textbox outside of the datatemplate and create a grid to put it above the listbox of ellipses. This works from a layout perspective, but creates a big mess in terms of checking for mouseover and centering the textbox on the control that's active/hovered.
So that leaves me without an implementation that works the way I want. Anyone have any suggestions?

Ok here I have another idea. I had problem with the ListBox before. Try replacing the ListBox with an ItemsControl.

Attempt #2 sounds like is working fine. You should be able to solve the issue of the clipping using one of these solutions (or all of them):
Set the ClipToBounds property of the ListBox to false
Set the ClipToBounds property of the Stackpanel to false

C# WPF: How to keep keyboard focus in main window?

I am working on a simple image viewer.
It contains a viewbox which shows the current image.
Below I added a thumbnail strip created by a wrappanel inside a listview which contains the thumbnails in viewboxes again.
I am able to switch the current image by key events (code excample "space", in real space and arrow keys). By clicking in one of the thumbs it is also possible to update the current image.
Unfortunately, whenever I select a thumb in the Listview, the Mainwindow looses keyboard focus and I am not able to use the keys anymore to switch the images.
I tried all solutions found in the net, but nothing really works, now I am completely lost.
Any ideas.

Changing border color when a control is selected with c# on windows 8 app store

I have a gridview control with images and text with this xaml:
<Grid Grid.Column="1" Margin="0,40,30,0" >
<GridView x:Name="celebGridView" Margin="0,0,0,0" Padding="0,0,0,0">
<GridView.ItemsPanel>
<ItemsPanelTemplate>
<WrapGrid Orientation="Horizontal" MaximumRowsOrColumns="3"/>
</ItemsPanelTemplate>
</GridView.ItemsPanel>
<GridView.Header>
<StackPanel Width="480" Margin="0,4,14,0">
<StackPanel Orientation="Horizontal" Margin="0,0,0,10">
<TextBlock Text="Most Viewed Celebs" Foreground="black" FontSize="25"/>
<Image Source="/images/Navigation-Right.png" Margin="10,0,0,0"/>
</StackPanel>
</StackPanel>
</GridView.Header>
<GridView.ItemTemplate>
<DataTemplate>
<StackPanel>
<Image Source="{Binding ImageBitmap}" />
<TextBlock HorizontalAlignment="Center" Text="{Binding Name_}" Foreground="Black"/>
</StackPanel>
</DataTemplate>
</GridView.ItemTemplate>
</GridView>
</Grid>
and i get this purple border around the selected items in the gridview below
How can i override this behaviour, i need to change the color to a custom color (#fdeb01).

You could edit the ItemContainerStyle for the GridView. The easiest way is to use Blend and find the SelectedBorder element and change stroke brush to color you want.

Aside from using Expression Blend, note that Metro ListView selection color modification in XAML is also valid for GridViewItems so changing the following:
<SolidColorBrush x:Key="ListViewItemSelectedBackgroundThemeBrush" Color="#fdeb01"> </SolidColorBrush>
<SolidColorBrush x:Key="ListViewItemPointerOverBackgroundThemeBrush" Color="#ffffff"></SolidColorBrush>
<SolidColorBrush x:Key="ListViewItemSelectedPointerOverBackgroundThemeBrush" Color="#fdeb01"></SolidColorBrush>
<SolidColorBrush x:Key="ListViewItemSelectedPointerOverBorderThemeBrush" Color="#fdeb01"></SolidColorBrush>
will also affect the gridview.

How to set animations/transitions when adding elements to a ListViews?

I have got a ListView wich I added Elements by binding. The ListView looks like:
<ListView
x:Name="ListView"
Height="auto"
Width="350"
ItemsSource="{Binding}"
Padding="0,0,-20,0"
Grid.Row="1"
Grid.Column="0"
Background="#EFEFEF"
ItemContainerStyle="{StaticResource ListViewStyle}">
<ListView.ItemTemplate>
<DataTemplate>
<StackPanel Height="50" VerticalAlignment="Top" Margin="0,0,0,0"
<TextBlock Text="{Binding name} TextWrapping="NoWrap"/>
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
With this basic setup there is already an animation when a element is bonded to the underlying List. Strangely to different animations are used. The first element slides in from the right and all other elements popup. I’m searching for a way to animate all added elements the same way (e.g. slide in from the right). I have been locking into the auto generated (by Blend) ListViewStyle for hours now but couldn't find something. Later I found out that it is possible to add this property inside the style:
<Style x:Key="ListViewStyle" TargetType="ListViewItem">
<Setter Property="Transitions">
<Setter.Value>
<TransitionCollection>
<EntranceThemeTransition FromHorizontalOffset="400" />
<PopupThemeTransition FromHorizontalOffset="400"/>
</TransitionCollection>
</Setter.Value>
</Setter>
...
</Style>
The EntranceThemeTransition and PopupThemeTransition seems to be the right properties because they change the behavior of the animation. But I don't know how to use them or how to disable one. How can I get just one animation (slide in from the right) to the ListView?

This should work:
<ListView
x:Name="lv">
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<VirtualizingStackPanel>
<VirtualizingStackPanel.ChildrenTransitions>
<TransitionCollection>
<EntranceThemeTransition
FromHorizontalOffset="400" />
</TransitionCollection>
</VirtualizingStackPanel.ChildrenTransitions>
</VirtualizingStackPanel>
</ItemsPanelTemplate>
</ListView.ItemsPanel>
</ListView>
*Update:
You can also use ListView.ItemContainerTransitions to define these transitions.

Add extra element to ItemsControl's Canvas

I have an ItemsControl set up like this:
<Grid>
<ItemsControl ItemsSource="{Binding Asteroids}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<Canvas Background="Black">
<!-- i want to add another polygon to the canvas-->
<!--<Polygon Name ="ShipPolygon" Points="{Binding Ship}" Fill="Blue" />-->
</Canvas>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Polygon Fill="Gray" Points="{Binding AsteroidPoints}" />
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
As you can see, the ItemsControl is displaying a collection's elements as Polygons in a Canvas. But i also want to add another Polygon to this Canvas, here named "ShipPolygon". I can't do that this way, because i get an XMLParseException. What is the proper method to do this? Thanks in advance!

You are using an ItemsControl, which is there to display multiple similar items on an itemspanel.
Now obviously you can't add something to your ItemsPanelTemplate there you are only telling the itemscontrol which panel it should use to display its items.
Your ItemsSource and your ItemTemplate suggest that you only want to show Asteroids in your ItemsControl. So the easiest way would be to just overlay your ship onto the itemscontrol with your asteroids
<Grid>
<ItemsControl ItemsSource="{Binding Asteroids}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<Canvas Background="Black"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Polygon Fill="Gray" Points="{Binding AsteroidPoints}" />
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
<Polygon Name ="ShipPolygon" Points="{Binding Ship}" Fill="Blue" />
</Grid>
Otherwise you could add it aswell to the itemscontrol, but then need to use different ItemTemplates. And you need to handle, that your ItemsControl no longer only holds Asteroids.
Using implicit item Templates
<!-- No key, so it is implicit and automatically used-->
<DataTemplate DataType="{x:Type Asteroids}">
<Polygon Fill="Gray" Points="{Binding AsteroidPoints}" />
</DataTemplate>
<DataTemplate DataType="{x:Type Player}">
<Polygon Name ="ShipPolygon" Points="{Binding Ship}" Fill="Blue" />
</DataTemplate>
<!-- above must be in a resource section, like app.xaml -->
<Grid>
<ItemsControl ItemsSource="{Binding Entities}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<Canvas Background="Black"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
</Grid>
Or you could use a DataTemplateSelector.
