Реших да персонализирам бутон за превключване с персонализиран стил: той съдържа изображение и текст. Нормалното състояние на моя бутон използва конкретно изображение и конкретен текст на преден план. проверяваното състояние използва други.
Обаче... превключвателят не работи за моите изображения.
Създадох персонализиран бутон за превключване. Кодът е точно тук:
class CustomToggleButton : ToggleButton
{
public String ImageSource
{
get { return (String)GetValue(ImageSourceProperty); }
set { SetValue(ImageSourceProperty, value); }
}
// Using a DependencyProperty as the backing store for ImageSource. This enables animation, styling, binding, etc...
public static readonly DependencyProperty ImageSourceProperty =
DependencyProperty.Register("ImageSource", typeof(String), typeof(CustomToggleButton), new PropertyMetadata(String.Empty));
public String SelectedImageSource
{
get { return (String)GetValue(SelectedImageSourceProperty); }
set { SetValue(SelectedImageSourceProperty, value); }
}
// Using a DependencyProperty as the backing store for SelectedImageSource. This enables animation, styling, binding, etc...
public static readonly DependencyProperty SelectedImageSourceProperty =
DependencyProperty.Register("SelectedImageSource", typeof(String), typeof(CustomToggleButton), new PropertyMetadata(String.Empty));
}
Използвам контрола си по този начин:
<controls:CustomToggleButton ImageSource="/Resources/home.png" SelectedImageSource="/Resources/home-neg.png" FontSize="18"
Content="Acceuil" Style="{StaticResource HamburgerMenuItemStyle}" VerticalAlignment="Stretch" HorizontalAlignment="Stretch"/>
Ето персонализирания стил на бутона за превключване:
<x:Double x:Key="TextStyleLargeFontSize">18.14</x:Double>
<Thickness x:Key="PhoneButtonContentPadding">9.5,0,9.5,3.5</Thickness>

Както можете да видите, аз се опитвам да задам моите персонализирани свойства на бутона за превключване за две различни състояния:
Нормално състояние:
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Source" Storyboard.TargetName="ToggleImage">
<DiscreteObjectKeyFrame KeyTime="0" Value="{Binding ImageSource}"/>
</ObjectAnimationUsingKeyFrames>
И Проверено състояние:
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Source" Storyboard.TargetName="ToggleImage">
<DiscreteObjectKeyFrame KeyTime="0" Value="{Binding SelectedImageSource}"/>
</ObjectAnimationUsingKeyFrames>
И... никак не става.
РЕДАКТИРАНЕ:
За заинтересованите колеги моето решение е достъпно по-долу.
