Windows Phone控制模板转换器:在程序集中从图像资源加载BitmapImage时出现问题

这基本上是我上一个问题的后续。我已经设法使这个工作与模板，但是，我想使它有点通用，这样我就不必到处重复代码
工作版本(硬编码)如下:
<UserControl.Resources>
<ControlTemplate x:Key="TrebleCheckboxImageTemplate" TargetType="CheckBox">
<Image x:Name="imgTreble" MinWidth="100" Source="Images/treble_checked.png">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CheckStates">
<VisualState x:Name="Checked">
<Storyboard>
<ObjectAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="imgTreble" Storyboard.TargetProperty="(Image.Source)">
<DiscreteObjectKeyFrame KeyTime="00:00:00">
<DiscreteObjectKeyFrame.Value>
<BitmapImage UriSource="Images/treble_checked.png" />
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
<VisualState x:Name="Unchecked">
<Storyboard>
<ObjectAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="imgTreble" Storyboard.TargetProperty="(Image.Source)">
<DiscreteObjectKeyFrame KeyTime="00:00:00">
<DiscreteObjectKeyFrame.Value>
<BitmapImage UriSource="Images/treble_unchecked.png" />
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
<VisualState x:Name="Indeterminate"/>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
</Image>
</ControlTemplate>
</UserControl.Resources>
<StackPanel x:Name="LayoutRoot" Background="{StaticResource PhoneForegroundBrush}" Orientation="Horizontal">
<CheckBox Height="72" HorizontalAlignment="Left" Background="White" VerticalAlignment="Top" Template="{StaticResource TrebleCheckboxImageTemplate}" Margin="0,0,10,0" >
<Custom:Interaction.Triggers>
<Custom:EventTrigger EventName="Click">
<GalaSoft_MvvmLight_Command:EventToCommand CommandParameter="{Binding RelativeSource={RelativeSource Self}, Path=IsChecked}" Command="{Binding TreblePressedCommand}"/>
</Custom:EventTrigger>
</Custom:Interaction.Triggers>
</CheckBox>
</StackPanel>
当然，图像路径是硬编码的。所以，我想让它通用，这样你就可以实例化一个复选框，告诉它它的图像，和模板将是相同的。
我创建了一个ImageCheckbox控件类:public class ImageCheckbox : CheckBox
{
/// <summary>
/// The <see cref="CheckedImagePath" /> dependency property's name.
/// </summary>
public const string CheckedImagePathPropertyName = "CheckedImagePath";
/// <summary>
/// Gets or sets the value of the <see cref="CheckedImagePath" />
/// property. This is a dependency property.
/// </summary>
public string CheckedImagePath
{
get
{
return (string)GetValue(CheckedImagePathProperty);
}
set
{
SetValue(CheckedImagePathProperty, value);
}
}
/// <summary>
/// Identifies the <see cref="CheckedImagePath" /> dependency property.
/// </summary>
public static readonly DependencyProperty CheckedImagePathProperty = DependencyProperty.Register(
CheckedImagePathPropertyName,
typeof(string),
typeof(ImageCheckbox),
new PropertyMetadata(null));
/// <summary>
/// The <see cref="UnCheckedImagePath" /> dependency property's name.
/// </summary>
public const string UnCheckedImagePathPropertyName = "UnCheckedImagePath";
/// <summary>
/// Gets or sets the value of the <see cref="UnCheckedImagePath" />
/// property. This is a dependency property.
/// </summary>
public string UnCheckedImagePath
{
get
{
return (string)GetValue(UnCheckedImagePathProperty);
}
set
{
SetValue(UnCheckedImagePathProperty, value);
}
}
/// <summary>
/// Identifies the <see cref="UnCheckedImagePath" /> dependency property.
/// </summary>
public static readonly DependencyProperty UnCheckedImagePathProperty = DependencyProperty.Register(
UnCheckedImagePathPropertyName,
typeof(string),
typeof(ImageCheckbox),
new PropertyMetadata(null));
}
我创建了一个转换器(因为我遇到了必须将字符串转换为图像源的Uri的问题)
public class StringToImageConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
if (value == null)
{
return null;
}
if (!UriParser.IsKnownScheme("pack"))
{
UriParser.Register(new GenericUriParser
(GenericUriParserOptions.GenericAuthority), "pack", -1);
}
if (value is string)
{
var image = new BitmapImage();
image.UriSource = new Uri(String.Format(@"pack://application:,,/Images/{0}", value as string));
//image.UriSource = new Uri(String.Format(@"pack://application:,,,/Adagio.Presentation;component/Images/{0}", value as string),UriKind.Absolute);
image.ImageFailed += new EventHandler<System.Windows.ExceptionRoutedEventArgs>(image_ImageFailed);
image.ImageOpened += new EventHandler<System.Windows.RoutedEventArgs>(image_ImageOpened);
return image;
}
if (value is Uri)
{
var bi = new BitmapImage {UriSource = (Uri) value};
return bi;
}
return null;
}
void image_ImageOpened(object sender, System.Windows.RoutedEventArgs e)
{
throw new NotImplementedException();
}
void image_ImageFailed(object sender, System.Windows.ExceptionRoutedEventArgs e)
{
throw new NotImplementedException();
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
}
你可以看到，转换器已经尝试了数千种不同的组合，没有一个工作…然后，新的xaml:
<ControlTemplate x:Key="CheckboxImageTemplate" TargetType="Controls:ImageCheckbox">
<Image x:Name="imgForTemplate" MinWidth="100" Source="{Binding RelativeSource={RelativeSource TemplatedParent},Path=CheckedImagePath, Converter={StaticResource stringToImageConverter}}">
<!--

</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
<VisualState x:Name="Indeterminate"/>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>-->
</Image>
</ControlTemplate>
<StackPanel x:Name="LayoutRoot" Background="{StaticResource PhoneForegroundBrush}" Orientation="Horizontal">
<Controls:ImageCheckbox CheckedImagePath="treble_checked.png" UnCheckedImagePath="treble_unchecked.png" Height="72" HorizontalAlignment="Left" VerticalAlignment="Top" Template="{StaticResource CheckboxImageTemplate}" Margin="0,0,10,0" >
<Custom:Interaction.Triggers>
<Custom:EventTrigger EventName="Click">

</Custom:EventTrigger>
</Custom:Interaction.Triggers>
</Controls:ImageCheckbox>
</StackPanel>
我试图使它全部工作在一开始，但我似乎甚至没有得到图像的第一个源属性加载。评论部分(VisualStateManager状态)也不工作，但我认为它必须是相同的问题。在这种情况下，我需要一个转换器来返回Uri而不是BitmapImage，因为UriSource的类型是Uri，而Source的类型是Image。我在转换器中得到错误，我无法加载图像(总是落入image_imageFailed事件)。我已经将图像设置为集合中的资源…我做错了什么?这快把我逼疯了!!!!
[EDIT]:我试过按照建议做，并将依赖属性更改为Uri，但我不能让它工作如果我输入
<Controls:ImageCheckbox CheckedImagePath="Images/treble_checked.png" UnCheckedImagePath="Images/treble_unchecked.png" Height="72" HorizontalAlignment="Left" VerticalAlignment="Top" Template="{StaticResource CheckboxImageTemplate}" Margin="0,0,10,0" >
和模板中的VisualState:
<BitmapImage UriSource="{Binding Path=UnCheckedImagePath, RelativeSource={RelativeSource TemplatedParent}}" />
它告诉我xaml是无效的，并得到一个错误。如果我像这样使用TemplateBinding:
<BitmapImage UriSource="{TemplateBinding UnCheckedImagePath}" />
它没有抱怨，但是图像没有加载(显示为空白)。我想我已经接近了，但还没有找到解决办法。
[EDIT 2]: last try…
用法:
<StackPanel x:Name="LayoutRoot" Background="{StaticResource PhoneForegroundBrush}" Orientation="Horizontal">
<Controls:ImageCheckbox Style="{StaticResource TheImageCheckboxStyle}" CheckedImagePath="Images/treble_checked.png" UnCheckedImagePath="Images/treble_unchecked.png" Height="72" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="0,0,10,0" >
<Custom:Interaction.Triggers>
<Custom:EventTrigger EventName="Click">
<GalaSoft_MvvmLight_Command:EventToCommand CommandParameter="{Binding RelativeSource={RelativeSource Self}, Path=IsChecked}" Command="{Binding TreblePressedCommand}"/>
</Custom:EventTrigger>
</Custom:Interaction.Triggers>
</Controls:ImageCheckbox>
</StackPanel>

您是否考虑过将CheckedImagePath的类型更改为Uri，并直接绑定到该类型，而不是创建BitmapImage ?
在我看来，你的代码过于复杂了一个简单的绑定。
编辑:这是我怎么做的(工作示例)
使用示例
<local:ImageCheckBox HorizontalAlignment="Left"
VerticalAlignment="Top"
CheckedImagePath="CheckedImage.png"
Content="CheckBox"
UnCheckedImagePath="UnCheckedImage.png" />
public partial class ImageCheckBox // NameSpace: MyControls
{
public ImageCheckBox()
{
InitializeComponent();
}
public const string CheckedImagePathPropertyName = "CheckedImagePath";
public Uri CheckedImagePath
{
get
{
return (Uri)GetValue(CheckedImagePathProperty);
}
set
{
SetValue(CheckedImagePathProperty, value);
}
}
public static readonly DependencyProperty CheckedImagePathProperty =
DependencyProperty.Register(CheckedImagePathPropertyName,
typeof(Uri), typeof(ImageCheckBox), new PropertyMetadata(null));
public const string UnCheckedImagePathPropertyName = "UnCheckedImagePath";
public Uri UnCheckedImagePath
{
get
{
return (Uri)GetValue(UnCheckedImagePathProperty);
}
set
{
SetValue(UnCheckedImagePathProperty, value);
}
}
public static readonly DependencyProperty UnCheckedImagePathProperty =
DependencyProperty.Register(UnCheckedImagePathPropertyName,
typeof(Uri), typeof(ImageCheckBox), new PropertyMetadata(null));
}
