How would I go about changing a TabItem color from it's unselected color to it's selected color with an animation on SelectionChanged, so that both the unselected and selected TabItems change?
Edit: This is how my CustomTemplate looks like. There is no animation happening at all so what have I done wrong?
<Style TargetType="TabItem">
<Setter Property="IsEnabled" Value="False" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="TabItem">
<Grid>
<Border BorderBrush="Transparent" BorderThickness="0" MinWidth="120">
<StackPanel Orientation="Vertical">
<ContentPresenter HorizontalAlignment="Center" ContentSource="Header" />
<Ellipse Name="Ellipse" Stroke="Black" StrokeThickness="1" Width="24" Height="24" Margin="5" Fill="Transparent" />
</StackPanel>
</Border>
</Grid>
<ControlTemplate.Triggers>

You can define custom TabItem template and run animations using triggers.

I attempted to create a simple style for a TabItem, by going to the Properties window and converting the template to a new resource, and wrapping it in a style (pretty standard stuff).
The goal is to animate the BorderBrush colour based on the IsSelected property. I've actually done this with relative ease, using the original generated code as a basis.
The problem: In the designer and when the application starts, all TabItems show as selected until I click on any tab which isn't the first one (index 0, since that's selected by default).
A screen recording demonstrating what happens:
https://i.gyazo.com/17e2f3c484029d4f5cd3021612b0f882.mp4
How can this be remedied? I have tried using the various trigger types and none seem to fix the problem.
The style code:
<Style TargetType="{x:Type TabItem}">
<Setter Property="OverridesDefaultStyle" Value="True"/>
<Setter Property="SnapsToDevicePixels" Value="True"/>
<Setter Property="Padding" Value="8,0"/>
<Setter Property="Height" Value="30"/>
<Setter Property="Margin" Value="0,0,1,0"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Border x:Name="ElementBorder" Height="30" Width="Auto" Background="#FF1F1F1F" BorderBrush="#FF00FF96" BorderThickness="0,0,0,2" CornerRadius="2,2,0,0" SnapsToDevicePixels="True">
<ContentPresenter TextBlock.Foreground="Silver"
ContentTemplate="{TemplateBinding HeaderTemplate}"
Content="{TemplateBinding Header}"
ContentStringFormat="{TemplateBinding HeaderStringFormat}"
ContentSource="Header"
HorizontalAlignment="{Binding HorizontalContentAlignment, RelativeSource={RelativeSource FindAncestor, AncestorLevel=1, AncestorType={x:Type ItemsControl}}}"
Margin="{TemplateBinding Padding}"
RecognizesAccessKey="True"
SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
VerticalAlignment="{Binding VerticalContentAlignment, RelativeSource={RelativeSource FindAncestor, AncestorLevel=1, AncestorType={x:Type ItemsControl}}}"/>
</Border>
<ControlTemplate.Triggers>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="IsSelected" Value="True"/>
</MultiTrigger.Conditions>
<MultiTrigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<ColorAnimation
Storyboard.TargetName="ElementBorder"
Storyboard.TargetProperty="(Control.BorderBrush).(SolidColorBrush.Color)"

</Storyboard>
</BeginStoryboard>

<MultiTrigger.ExitActions>

The problem is that you set your default BorderBrush to be the selected color. Change it to be the unselected color like so:
<Border x:Name="ElementBorder"
Width="Auto"
Height="30"
Background="#FF1F1F1F"
BorderBrush="#FF1F1F1F"
BorderThickness="0,0,0,2"
CornerRadius="2,2,0,0"
SnapsToDevicePixels="True">
Also, you can simplify your trigger:
<Trigger Property="IsSelected" Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<ColorAnimation
Storyboard.TargetName="ElementBorder"
Storyboard.TargetProperty="(Control.BorderBrush).(SolidColorBrush.Color)"
To="#FF00FF96"
Duration="0:0:0.1" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
<Trigger.ExitActions>
<BeginStoryboard>
<Storyboard>
<ColorAnimation
Storyboard.TargetName="ElementBorder"
Storyboard.TargetProperty="(Control.BorderBrush).(SolidColorBrush.Color)"
To="#FF1F1F1F"
Duration="0:0:0.1" />
</Storyboard>
</BeginStoryboard>
</Trigger.ExitActions>
</Trigger>
In this animated ToggleButton ControlTemplate, upon clicking it does it's animation which rotates the Path when IsChecked is changed.
<ControlTemplate x:Key="AnimatedExpanderButtonTemp" TargetType="{x:Type ToggleButton}">
<Border x:Name="ExpanderButtonBorder"
Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}"

<Grid>

</Path>
</Grid>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetName="Arrow"
Storyboard.TargetProperty="(UIElement.RenderTransform).(RotateTransform.Angle)"
To="180"
Duration="0:0:0.4"/>
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
<Trigger.ExitActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetName="Arrow"

</Storyboard>
</BeginStoryboard>
</Trigger.ExitActions>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
However there are conditions where I don't want the animation to play out.
Such when the ToggleButton is first loaded and it is pre-checked,
or,
if using it in a VirtualizingPanel and the button row goes out of scope and comes back in again.
Some scenerios:
1) If it is pre-checked and not from a click then it goes straight to rotating the Arrow 180 degrees without animation.
2) If it is clicked and Checked is True, it rotates to 180 animated.
3) If it is clicked and Checked is False, it rotates to 0 animated.
How can I accomplish this?
Try something like this:
<ControlTemplate.Triggers>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="IsChecked" Value="True" />
<Condition Property="IsPressed" Value="False" />
<!--<Condition Property="IsMouseOver" Value="False" /> not sure if needed in your case-->
</MultiTrigger.Conditions>
<!--your logic for changing without animation-->
<!--<Setter Property="" Value="" />-->
</MultiTrigger>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="IsChecked" Value="True" />
<Condition Property="IsPressed" Value="True" />
<!--<Condition Property="IsMouseOver" Value="False" /> not sure if needed in your case-->
</MultiTrigger.Conditions>
<!--your logic for changing with animation-->
<!--<Setter Property="" Value="" />-->
</MultiTrigger>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="IsChecked" Value="False" />
<Condition Property="IsPressed" Value="True" />
<!--<Condition Property="IsMouseOver" Value="False" /> not sure if needed in your case-->
</MultiTrigger.Conditions>
<!--your logic for changing with animation-->
<!--<Setter Property="" Value="" />-->
</MultiTrigger>
</ControlTemplate.Triggers>
I have a reset button - the desired behaviour is to increase in size on mouseover and, once clicked, have a border around it.
The IsMouseOver trigger works, but I can't get the MouseUp event trigger to work (once pressed the button does not display a border).
I have tried the following:
1) Adding an event trigger to the control template triggers
2) Adding an event trigger to the style triggers
3) Adding an event trigger to the button triggers
Am I writing the event trigger incorrectly? I've added the code for the three attempts below - hoping I've just missed something obvious and is a quick fix. Thanks!

To animate Thickness, you have to use ThicknessAnimation
Button does not fire MouseLeftButtonUp routed event. Workaround is to use PreviewMouseLeftButtonUp event. Source
You have to bind your "Border" element properties BorderBrush and BorderThickness to your template.
For your first case:

<Setter Property="FocusVisualStyle" Value="{x:Null}" />
<Setter Property="MinHeight" Value="25" />
<Setter Property="MinWidth" Value="25" />
<Setter Property="BorderBrush" Value="Transparent" />
<Setter Property="BorderThickness" Value="0" />
<Setter Property="RenderTransform">

NOTE that MouseUp is firing only for Right mouse button up
Hope, it helps
The reason why these methods don't work is because the MouseUp event is consumed by the button, and never gets to your handler. This can be demonstrated by a right click (which isn't consumed) instead of a left click, and your above code will work (I only tested the first sample).
To solve this you can use use the PreviewMouseUp event instead. This worked for me in your first sample.

How can i control the animation of the Rectangle property of my button through code behind upon clicking the button.
The Rectangle named "progressIndicator" is to grow in width through animation when the user clicks the button.
Currently animation starts in Xaml. Why do you want to it in code-behind?
