A quick bit of DP help
Sacha Barber
I am trying to create a Style/Template for some buttons in my app in WPF.
The button uses the Tag property to store a url for an image that gets used in the Template. I also want the Button to pulse to some scale bigger than its declared scale.
I want to use an attached property to allow the button scale to be different in different parts of my app.
So I have something like
using System.Windows;
namespace DirectPlusDemoApp
{
public static class ButtonExtraProps
{
public static bool GetScaleTo(DependencyObject obj)
{
return (bool)obj.GetValue(ScaleToProperty);
}
public static void SetScaleTo(
DependencyObject obj, bool value)
{
obj.SetValue(ScaleToProperty, value);
}
public static readonly DependencyProperty ScaleToProperty =
DependencyProperty.RegisterAttached(
"ScaleTo",
typeof(double),
typeof(ButtonExtraProps),
new UIPropertyMetadata(1.0));
}
}
And here is the button Style
<Style x:Key="ButtonWithImageStyle" TargetType="{x:Type Button}">
<Setter Property="Margin" Value="4"/>
<Setter Property="Width" Value="25"/>
<Setter Property="Height" Value="25"/>
<Setter Property="Background" Value="WhiteSmoke"/>
<Setter Property="(local:ButtonExtraProps.ScaleTo)" Value="1.0"/>
<Setter Property="Template" Value="{StaticResource buttonWithImageTemplate}"/>
</Style>
which uses the previously declared Template
<ControlTemplate x:Key="buttonWithImageTemplate" TargetType="{x:Type Button}">
<Border x:Name="border" CornerRadius="4" RenderTransformOrigin="0.5,0.5"
Background="{TemplateBinding Background}"
BorderBrush="Transparent"
HorizontalAlignment="Center"
Width="{TemplateBinding Width}"
Height="{TemplateBinding Height}"
BorderThickness="2" Visibility="Visible">
<Border.RenderTransform>
<TransformGroup>
<ScaleTransform x:Name="imgScale" ScaleX="0.8" ScaleY="0.8"/>
<SkewTransform AngleX="0" AngleY="0"/>
<RotateTransform Angle="0"/>
<TranslateTransform X="0" Y="0"/>
</TransformGroup>
</Border.RenderTransform>
<Image Source="{Binding RelativeSource={RelativeSource TemplatedParent},
Path=Tag}" HorizontalAlignment="Center" VerticalAlignment="Center"
Margin="{TemplateBinding Padding}">
</Image>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="false">
<Setter TargetName="border" Property="Opacity" Value="0.4"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="true">
<Setter TargetName="border" Property="Background" Value="WhiteSmoke"/>
<Setter TargetName="border" Property="BorderBrush" Value="LightGray"/>
</Trigger>
<EventTrigger RoutedEvent="Mouse.MouseEnter">
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Duration="0:0:0.2" Storyboard.TargetName="imgScale"
Storyboard.TargetProperty="(ScaleTransform.ScaleX)" To="1.0" AutoReverse="True"/>
<DoubleAnimation Duration="0:0:0.2" Storyboard.TargetName="imgScale"
Storyboard.TargetProperty="(ScaleTransform.ScaleY)" To="1.0" AutoReverse="True"/>
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</ControlTemplate.Triggers>
</ControlTemplate>
What I want to replace is the hardcoded values of 1.0 in the MouseEnter StoryBoard.
I am decalring local NS at top of file like
xmlns:local="clr-namespace:DirectPlusDemoApp;assembly="
but when I try and compile I get an error with the namespace, and im not sure about the syntax for working with Attached props in story boards and Styles. Is what I am trying eevn correct. I am trying to do
<Setter Property="(local:ButtonExtraProps.ScaleTo)" Value="1.0"/>
in the style, which I think is ok, but what the heck do I do in the stoeyboard, I tried
<DoubleAnimation Duration="0:0:0.2" Storyboard.TargetName="imgScale"
Storyboard.TargetProperty="(ScaleTransform.ScaleX)" To="{TemplateBinding (local:ButtonExtraProps.ScaleTo)}" AutoReverse="True"/>
Can anyone give me some advice on this matter
Thanks

You're clr get/set methods are dealing with bool but you're registering a double property.
