Make the button transparent above the mouse

I am creating a subway style application using Microsoft Visual Studio Express 2012. I am very new to these applications and I need help. I defined the button in XAML with the button background set from the image. When you hover over a button, it changes the background to blank. I want to change it by making the image about 50% transparent on the mouse. Is it possible? Any help? Thanks.

I declared the button as follows:

<Button Height="100" Width="100" Margin="0,0,0,0"> <Button.Background> <ImageBrush ImageSource="../Images/home.png"></ImageBrush> </Button.Background> </Button>

An interactivity disc does not exist for Windows Store applications. Instead, you should use Visual States. This is easy to achieve with Blend.

If you open your application in Blend and edit a copy of the button template, you will get the full default button style in your xaml. You just need to edit the visual state of PointerOver to achieve what you want.

Your button will look like this:

 <Button Height="100" Width="100" Margin="0,0,0,0" Style="{StaticResource ButtonStyle1}"> <Button.Background> <ImageBrush ImageSource="/Assets/Images/home.png"></ImageBrush> </Button.Background> </Button>

and you will need to define a style in the resources of your application so that it can be used everywhere.

In the code below, view the visual status of PointerOver. It determines how the button should change when it enters this state. Here we say that the opacity of the border (which is the content displaying the background image) should be 0.5:

 <DoubleAnimation Duration="0" To="0.5" Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="Border" d:IsOptimized="True"/>

Here is the full style:

 <Style x:Key="ButtonStyle1" TargetType="Button"> <Setter Property="Background" Value="{StaticResource ButtonBackgroundThemeBrush}"/> <Setter Property="Foreground" Value="{StaticResource ButtonForegroundThemeBrush}"/> <Setter Property="BorderBrush" Value="{StaticResource ButtonBorderThemeBrush}"/> <Setter Property="BorderThickness" Value="{StaticResource ButtonBorderThemeThickness}"/> <Setter Property="Padding" Value="12,4,12,4"/> <Setter Property="HorizontalAlignment" Value="Left"/> <Setter Property="VerticalAlignment" Value="Center"/> <Setter Property="FontFamily" Value="{StaticResource ContentControlThemeFontFamily}"/> <Setter Property="FontWeight" Value="SemiBold"/> <Setter Property="FontSize" Value="{StaticResource ControlContentThemeFontSize}"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="Button"> <Grid> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="CommonStates"> <VisualState x:Name="Normal"/> <VisualState x:Name="PointerOver"> <Storyboard> <DoubleAnimation Duration="0" To="0.5" Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="Border" d:IsOptimized="True"/> </Storyboard> </VisualState> <VisualState x:Name="Pressed"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Background" Storyboard.TargetName="Border"> <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource ButtonPressedBackgroundThemeBrush}"/> </ObjectAnimationUsingKeyFrames> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Foreground" Storyboard.TargetName="ContentPresenter"> <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource ButtonPressedForegroundThemeBrush}"/> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> <VisualState x:Name="Disabled"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Background" Storyboard.TargetName="Border"> <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource ButtonDisabledBackgroundThemeBrush}"/> </ObjectAnimationUsingKeyFrames> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="BorderBrush" Storyboard.TargetName="Border"> <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource ButtonDisabledBorderThemeBrush}"/> </ObjectAnimationUsingKeyFrames> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Foreground" Storyboard.TargetName="ContentPresenter"> <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource ButtonDisabledForegroundThemeBrush}"/> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> </VisualStateGroup> <VisualStateGroup x:Name="FocusStates"> <VisualState x:Name="Focused"> <Storyboard> <DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="FocusVisualWhite"/> <DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="FocusVisualBlack"/> </Storyboard> </VisualState> <VisualState x:Name="Unfocused"/> <VisualState x:Name="PointerFocused"/> </VisualStateGroup> </VisualStateManager.VisualStateGroups> <Border x:Name="Border" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Margin="3"> <ContentPresenter x:Name="ContentPresenter" ContentTemplate="{TemplateBinding ContentTemplate}" ContentTransitions="{TemplateBinding ContentTransitions}" Content="{TemplateBinding Content}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/> </Border> <Rectangle x:Name="FocusVisualWhite" IsHitTestVisible="False" Opacity="0" StrokeDashOffset="1.5" StrokeEndLineCap="Square" Stroke="{StaticResource FocusVisualWhiteStrokeThemeBrush}" StrokeDashArray="1,1"/> <Rectangle x:Name="FocusVisualBlack" IsHitTestVisible="False" Opacity="0" StrokeDashOffset="0.5" StrokeEndLineCap="Square" Stroke="{StaticResource FocusVisualBlackStrokeThemeBrush}" StrokeDashArray="1,1"/> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style>
