У меня есть производный класс (надеюсь, что я создал правильно)

Когда я делаю {Binding idleSprite}, привязка ничего не делает, я даже пытался с помощью свойства строки показать в TextBlock, но безрезультатно.
Это то, что мой код ищет для этого элемента управления.

{

public static DependencyProperty idleSpriteProperty = DependencyProperty.Register(

public spriteToggleButton()
{
InitializeComponent();
}
public Dictionary<string, Quiz.Sprite> Sprites
{
get { return (Dictionary<string,Quiz.Sprite>)GetValue(SpritesProperty); }
set { SetValue(SpritesProperty, value); }
}
public static DependencyProperty SpritesProperty = DependencyProperty.Register(
"Sprites", typeof(Dictionary<string, Quiz.Sprite>), typeof(spriteToggleButton), new PropertyMetadata(new Dictionary<string, Quiz.Sprite>(), OnSpritesPropertyValueChanged));
private static void OnSpritesPropertyValueChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
var control = d as spriteToggleButton;
var sprites = e.NewValue as Dictionary<string, Quiz.Sprite>;
control.idleSprite = sprites["idle"];
control.selectedSprite = sprites["selected"];
control.highlightedSprite = sprites["highlighted"];
}
public string Text { get { return (string)GetValue(TextProperty); } set { SetValue(TextProperty, value); } }
public static DependencyProperty TextProperty = DependencyProperty.Register(
"Text", typeof(string), typeof(spriteToggleButton), new PropertyMetadata("", OnTextPropertyValueChanged));
private static void OnTextPropertyValueChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
var control = d as spriteToggleButton;
var contentText = e.NewValue as string;
control.spriteButton.Content = contentText;
}
public Boolean Selected { get { return (Boolean)GetValue(SelectedProperty); } set { SetValue(SelectedProperty, value); } }
public static DependencyProperty SelectedProperty = DependencyProperty.Register(
"Selected", typeof(Boolean), typeof(spriteToggleButton), new PropertyMetadata(false, OnSelectedPropertyValueChanged));
private static void OnSelectedPropertyValueChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
var control = d as spriteToggleButton;
var selectedValue = (Boolean)e.NewValue;
control.spriteButton.IsChecked = selectedValue;
}
}
}
OnSpritesPropertyValueChanged выполняется, но привязки по-прежнему не работают, я даже добавляю событие Loaded для проверки, и свойство Sprites было значением по умолчанию вместо того, что я его установил (но, возможно, Loaded запускается до свойства зависимости) установлены)
Он перестал работать примерно в то время, когда я обновил UserControl в производном ToggleButton, что я, возможно, сделал неправильно.
Надеюсь, этого достаточно, чтобы исправить эту проблему.
В ListBox, который использовал spriteToggleButton, я отправляю свойства, и они отправляются совершенно так.
<local:spriteToggleButton HorizontalAlignment="Center" Text="{Binding text}" Sprites="{Binding Path=DataContext.UISprites, ElementName=questionField}" Selected="{Binding Selected}" Checked="optionChecked" />
За исключением случаев, когда я повторяю процесс внутри spriteToggleButton, но у меня там зарегистрированы свойства зависимостей, так что, возможно, пропущен шаг с datacontext.
