WPF XAML Animate/blinking a button on mouse over - c#

I have a custom message box with two button 'Yes' and 'No'. Button 'Yes' is green and button 'No' is red.
I apply the same style for the two buttons through a xaml file defined separately as below:
MsgBoxButtonStyle.xaml:
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Style TargetType="Button"
x:Key="MsgBoxButtonStyle">
<Setter Property="Background"
Value="Transparent" />
<Setter Property="TextBlock.TextAlignment"
Value="Center" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border Name="Border" CornerRadius="0"
BorderBrush="#000" BorderThickness="1,1,1,1"
Background="{TemplateBinding Background}">
<ContentPresenter x:Name="contentPresenter"
ContentTemplate="{TemplateBinding ContentTemplate}"
Content="{TemplateBinding Content}"
HorizontalAlignment="{TemplateBinding HorizontalAlignment}"
Margin="{TemplateBinding Padding}"
VerticalAlignment="{TemplateBinding VerticalAlignment}" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ResourceDictionary>
These two buttons are place in my WPF window as below:
<Window x:Class="My.XAML.Controls.Windows.WpfMessageBox"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation">
<Window.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/My.XAML;component/Styles/MsgBoxButtonStyle.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Window.Resources>
<Button Name="btnYes" Content="Yes"
Click="Button_Click" Foreground="Black"
Style="{StaticResource MsgBoxButtonStyle}"
Background="#b6dbd6"
VerticalAlignment="Center" HorizontalAlignment="Stretch"
VerticalContentAlignment="Center" HorizontalContentAlignment="Center"/>
<Button Name="btnNo" Content="No"
Click="Button_Click" Foreground="Black"
Style="{StaticResource MsgBoxButtonStyle}"
Background="#dbb6b6"
VerticalAlignment="Center" HorizontalAlignment="Stretch"
VerticalContentAlignment="Center" HorizontalContentAlignment="Center" />
</Window>
Now, I would like to perform a nice effect when mouse is positioned over the buttons, some kind of blinking or whatever using storyboard and dependant on the color of the button.
Also I would like to put this storyboard within my existing style file MsgBoxButtonStyle.xaml and no put each storyboard in the window for each button, i want to share it.
How can I do this? some one can provide me a nice effect for buttons?

Just add triggers to the style. Here's an example to start you off.
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<ThicknessAnimation Duration="0:0:0.250" To="0"
Storyboard.TargetProperty="BorderThickness" />
<DoubleAnimation Duration="0:0:0.550" To="120"
Storyboard.TargetProperty="Height" />
<DoubleAnimation Duration="0:0:0.550" To="120"
Storyboard.TargetProperty="Width" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
<Trigger.ExitActions>
<BeginStoryboard>
<Storyboard>
<ThicknessAnimation Duration="0:0:0.250" To="0"
Storyboard.TargetProperty="BorderThickness" />
<DoubleAnimation Duration="0:0:0.550" To="100"
Storyboard.TargetProperty="Height" />
<DoubleAnimation Duration="0:0:0.550" To="100"
Storyboard.TargetProperty="Width" />
</Storyboard>
</BeginStoryboard>
</Trigger.ExitActions>
</Trigger>
</Style.Triggers>

Binding to an ancestor property inside an animation in WPF

I have a WPF page with a TabControl in it, and I wanted to design the tabs to have a nice underline when selected and on mouse hover.
I've managed to do that but each tab has a different length, and it seems that I can't bind a property of the TabItem inside of its animation.
This is what i have done so far:
<TabControl Width="{Binding ActualWidth,
ElementName=cnvsMain}" Height="{Binding
ActualHeight, ElementName=cnvsMain}"
BorderThickness="0" >
<TabControl.Resources>
<Style TargetType="TabItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="TabItem">
<StackPanel>
<Border Name="Border"
BorderThickness="1,1,1,0"
BorderBrush="Gainsboro"
CornerRadius="6,6,0,0"
Margin="2,0">
<ContentPresenter x:Name="ContentSite"
VerticalAlignment="Center"
HorizontalAlignment="Center"
ContentSource="Header"
Margin="10,2"/>
</Border>
<Label Name="TabUnderline" Background="LimeGreen"
Margin=" 5, 0" Height="5" Width="0"/>
</StackPanel>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation
Storyboard.TargetName="TabUnderline"
Storyboard.TargetProperty="Width"
From="0" To="100"
Duration="0:0:0.1"
AutoReverse="False" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
<Trigger.ExitActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation
Storyboard.TargetName="TabUnderline"
Storyboard.TargetProperty="Width"
From="100" To="0" Duration="0:0:0.1"
AutoReverse="False" />
</Storyboard>
</BeginStoryboard>
</Trigger.ExitActions>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</TabControl.Resources>
<TabItem Header="Rooms">
<StackPanel>
<Label Content="TODO: List all rooms" />
<Label Content="TODO: Create room button" />
</StackPanel>
</TabItem>
<TabItem Header="Statistics" />
<TabItem Header="Details" />
</TabControl>
It works great but there is one simple flaw:
The under line will always be 100 pixels (Or is it units?) wide, and each tab has its unique and different width. I've tried to replace the hard-coded 100 to {Binding ActualWidth} or using a RelativeSource to get the width of the TabItem, but I keep getting an exception everytime this page is being loaded because of a binding-error.
How can I bind a TabItem's property to a value inside its own animation? Is it even possible?

Animate button background image on IsMouseOver in WPF/XAML/C#

Based on the code below, is it possible to animate the transition from image1 to image2 on button IsMouseOverevent?
The following code works fine showing image1 as the upstate image and image2 as the hover image on a button but it does not animate the transition.
XAML Style
<Style x:Key="MainMenuButtonTemplate" TargetType="{x:Type Button}">

<Setter Property="Template">

Usage
<Button x:Name="findRButton"

<Button.Background>
<ImageBrush ImageSource="Images/image1.png" Stretch="None"/>
</Button.Background>
</Button>
Here is code that shows you how to do what you're looking for.
In order to use animations during triggers you must utilize the enter and exit actions of that trigger. You must also name BeginStoryboard so that you can stop it in other calls.
Review the code and if you have anymore questions let me know. This will fade from image1 to image2 and vice versa with mouse over / leave.

WPF Style Storyboard To Another Objects Value

Here I have a button style in appliction resources
<Style x:Key="ClickableText" TargetType="{x:Type Button}">
<Setter Property="BorderBrush" Value="{x:Null}"/>
<Setter Property="FontFamily" Value="/Tasks;component/Assets/Fonts/#Abel"/>
<Setter Property="Background" Value="Transparent" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Background="{TemplateBinding Background}">
<StackPanel VerticalAlignment="Center">
<ContentPresenter x:Name="Text" HorizontalAlignment="Center" VerticalAlignment="Center"/>
<Rectangle x:Name="Rect1" Width="{Binding ActualWidth, ElementName=Text}" Height="2" Fill="{DynamicResource LightGrey}"/>
</StackPanel>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="White"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
In the style I have added a underlining rectangle to the text in the button.
<Rectangle x:Name="Rect1" Width="{Binding ActualWidth, ElementName=Text}" Height="2" Fill="{DynamicResource LightGrey}"/>
I have binded the rectangles width to be the same width as the text so that it adds a underline effect.
I now want to add an effect so that when you hover the button the rectangle reveals by spliting out.
I have got this far by adding this under the trigger tag
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Duration="0:0:0.300" From="0" To="{Binding ActualWidth, ElementName=Text}" Storyboard.TargetName="Rect1" Storyboard.TargetProperty="Width" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
<Trigger.ExitActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Duration="0:0:0.300" From="{Binding ActualWidth, ElementName=Text}" To="0" Storyboard.TargetName="Rect1" Storyboard.TargetProperty="Width" />
</Storyboard>
</BeginStoryboard>
</Trigger.ExitActions>
I want to link the to and from part of the double animation to the binding I used in the rectangle but it keeps producing errors. How can I do this effect?
I also want to use this as a reusable style I can distribute and keep in Application resources. I have seen other people do this through workarounds in code but am not sure if you can do this in application resources
Any help or guidance is greatly appriciated!!
LayoutTransform animation is Better for this effect.
I would do this animation in this way:
<Style x:Key="ClickableText" TargetType="{x:Type Button}">
<Setter Property="BorderBrush" Value="{x:Null}"/>
<Setter Property="FontFamily" Value="/Tasks;component/Assets/Fonts/#Abel"/>
<Setter Property="Background" Value="Transparent" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="MainBorder" Background="{TemplateBinding Background}">
<Grid HorizontalAlignment="Center" VerticalAlignment="Center">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="2"/>
</Grid.RowDefinitions>
<ContentPresenter x:Name="Text" Grid.Row="0" HorizontalAlignment="Center" VerticalAlignment="Center"/>
<Rectangle x:Name="Rect1" Grid.Row="1" Height="2" Width="{Binding ElementName=Text, Path=ActualWidth}" Fill="LightGray">
<Rectangle.LayoutTransform>
<ScaleTransform ScaleX="0"/>
</Rectangle.LayoutTransform>
</Rectangle>
</Grid>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" TargetName="MainBorder" Value="White"/>
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetName="Rect1" Storyboard.TargetProperty="(ContentPresenter.LayoutTransform).(ScaleTransform.ScaleX)" From="0" To="1" Duration="0:0:0.2" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
<Trigger.ExitActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetName="Rect1" Storyboard.TargetProperty="(ContentPresenter.LayoutTransform).(ScaleTransform.ScaleX)" From="1" To="0" Duration="0:0:0.2" />
</Storyboard>
</BeginStoryboard>
</Trigger.ExitActions>
</Trigger>
</ControlTemplate.Triggers>

Wpf button with both result datatrigger storyboard and mouseover background

I'm looking to implement this functionality: A button, bound to a command, that can signal back wether the command was successful in form of a red or green flash. At the same time, I want the button to look like other buttons.
This is the code I have now:
<Button IsEnabled="{Binding EmptyingAllowed}" Content="Töm lista" Foreground="#555555" FontWeight="SemiBold" Height="20" Width="65" Command="{Binding EmptyListCommand}" >
<Button.Style>
<Style TargetType="Button">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border BorderBrush="#BBBBBB" Padding="1" BorderThickness="0,0,1,1" Background="#DDDDDD">
<Grid Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
</Grid>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<DataTrigger Binding="{Binding ClearedOk}" Value="Ok">
<DataTrigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<ColorAnimation AccelerationRatio="0.2" DecelerationRatio="0.01" AutoReverse="True" Duration="0:0:1" To="LawnGreen" Storyboard.TargetProperty="(Button.Background).(SolidColorBrush.Color)"/>
</Storyboard>
</BeginStoryboard>
</DataTrigger.EnterActions>
</DataTrigger>
<DataTrigger Binding="{Binding ClearedOk}" Value="Error">
<DataTrigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<ColorAnimation AccelerationRatio="0.2" DecelerationRatio="0.01" AutoReverse="True" Duration="0:0:1" To="Red" Storyboard.TargetProperty="(Button.Background).(SolidColorBrush.Color)"/>
</Storyboard>
</BeginStoryboard>
</DataTrigger.EnterActions>
</DataTrigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>
When the command is executed, ClearedOk is set to "Ok" or "Error" and then to "Empty", this causes the flash I'm looking for, unfortunately, the usual mouseOver-effect is lost for some reason, and if I add a mouseOver-trigger, it always takes precedence over the flashing effect, meaning the flash is only visible of the button isn't mouseOver:ed.
Is there a solution to this?
Try to make datatemplate and model with properties of state and then binding in template to this properties.
<DataTemplate x:Key="DataTemplate">
<Grid >
<Ellipse Stroke="White"
StrokeThickness="5"
Fill="{Binding State, Converter={StaticResource CheckToColorConverter}}"/>
</Grid>
</DataTemplate>

App Crashes when changing tabs that contain listboxes with control templates on ItemContainerStyle and bound to CollectionViewSource

my problem is that i have three tab controls each with a listbox that has style for both the ListBox and the ItemContainerStyle, the styles are the same on all listboxes inside the tabs.
two of the tabs are databound using a CollectionViewSource.
The problem is as soon as i try to go into tab 2 i get an exception and i cant seem to find out where from (i tired enabling first chance exceptions as well and nothing )
playing around with it i found out that if i remove the ItemContainerStyle form the ListBox in tab two it no longer crashes. another way to stop it form crashing is not to have any items in the listbox. and another way is instead of using a CollectionViewSource
use a GetDefaultView() on the list and bind to that.
here are the lines i use to bind to the listboxes:
this.FListViewSource = (this.FindResource("FirstCollectionViewSource") as AutoRefreshCollectionViewSource);
this.FListViewSource.Source = this.FirstList;
this.FListView = (this.FListViewSource.View as ListCollectionView);
this.SListViewSource = (this.FindResource("SecondCollectionViewSource") as AutoRefreshCollectionViewSource);
this.SListViewSource.Source = testing;
this.SListView = (this.SListViewSource.View as ListCollectionView);
this is the XAML for the tab control :
<TabControl Width="Auto" Height="Auto">
<TabItem Header="tab 1">
<StackPanel Name =first_Panel" >
<ListBox Style="{StaticResource lb_ms}" ItemContainerStyle="{StaticResource black_lb}" Width="160" Name="first_lb"

</StackPanel>
</TabItem>
<TabItem Header="tab 2">
<StackPanel Name ="second_Panel" DataContext="{Binding Source={StaticResource FirstCollectionViewSource}}" FlowDirection="LeftToRight" Background="#333333">
<ListBox ItemsSource="{Binding}" Style="{StaticResource lb_ms}" ItemContainerStyle="{StaticResource black_lb}" Width="160" Name="second_lb"

For it not to crash i had to add SelectionMode="Multiple" on the listbox that used the style, the question is why?
