wpf C# xaml

在我的 Generic.xaml 中，我有许多样式的表单：

  <Style x:Key="ToggleButtonStyle12" TargetType="{x:Type ToggleButton}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type ToggleButton}">
                    <Grid>
                        <Path x:Name="path1" Data="{StaticResource InsideQuarter3}" Fill="DarkOrange" Stroke="Black" />
                        <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" RecognizesAccessKey="True" 
                                          SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                    </Grid>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsMouseOver" Value="true">
                            <Setter TargetName="path1" Property = "Opacity" Value="0.4"/>
                        </Trigger>
                        <Trigger Property="IsChecked" Value="true">
                            <Trigger.EnterActions>
                                <BeginStoryboard Storyboard="{StaticResource Blink_On}"/>
                            </Trigger.EnterActions>
                            <Trigger.ExitActions>
                                <BeginStoryboard Storyboard="{StaticResource Blink_Off}"/>
                            </Trigger.ExitActions>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

所有这些切换按钮之间的唯一区别是路径定义和填充颜色。

是否可以以仅需要提供路径和填充颜色的方式对这种样式进行模板化/简化？

这类似于：

<Style x:Key="ToggleButtonStyle12" BasedOn(??????)>
    <Setter Property = "Path" Value="InsideQuarter3"/>
    <Setter Property = "Fill" Value="DarkOrange"/>
</Style>

感谢您的任何帮助。

编辑#1 好吧，我以为我知道了——我错了。下面的代码将正确设置路径数据和填充属性。但是，只有第一个创建的 ToggleButton 保留了“MouseOver”和其他 ControlTemplate.Triggers。我需要RingControl 中的所有切换按钮来尊重它们自己的触发器。

  public static class ButtonProperties
    {
        public static Color GetMyForegroundColor(DependencyObject obj)
        {
            return (Color)obj.GetValue(MyForegroundColorProperty);
        }

        public static void SetMyForegroundColor(DependencyObject obj, Color value)
        {
            obj.SetValue(MyForegroundColorProperty, value);
        }

        // Using a DependencyProperty as the backing store for MyForegroundColor.  This enables animation, styling, binding, etc...
        public static readonly DependencyProperty MyForegroundColorProperty =
            DependencyProperty.RegisterAttached("MyForegroundColor", typeof(Color), typeof(ButtonProperties), new PropertyMetadata(Colors.Black));



        public static Geometry GetData(DependencyObject obj)
        {
            return (Geometry)obj.GetValue(DataProperty);
        }

        public static void SetData(DependencyObject obj, Geometry value)
        {
            obj.SetValue(DataProperty, value);
        }

        // Using a DependencyProperty as the backing store for Data.  This enables animation, styling, binding, etc...
        public static readonly DependencyProperty DataProperty =
            DependencyProperty.RegisterAttached("Data", typeof(Geometry), typeof(ButtonProperties), new PropertyMetadata(null));



        public static Brush GetFill(DependencyObject obj)
        {
            return (Brush)obj.GetValue(FillProperty);
        }

        public static void SetFill(DependencyObject obj, Brush value)
        {
            obj.SetValue(FillProperty, value);
        }

        // Using a DependencyProperty as the backing store for Fill.  This enables animation, styling, binding, etc...
        public static readonly DependencyProperty FillProperty =
            DependencyProperty.RegisterAttached("Fill", typeof(Brush), typeof(ButtonProperties), new PropertyMetadata(null));

    }

Generic.xaml -- BaseButtonStyle

  <Style x:Key="BaseButtonStyle" TargetType="{x:Type ToggleButton}">
        <Setter Property="local:ButtonProperties.MyForegroundColor" Value="Blue"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type ToggleButton}">
                    <Grid>
                    <TextBlock Text="Some Text">
                        <TextBlock.Foreground>
                            <SolidColorBrush Color="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=(local:ButtonProperties.MyForegroundColor)}" />
                        </TextBlock.Foreground>

                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

Generic.xaml -- ModifiedButtonStyle1

 <Style x:Key="ModifiedButtonStyle1" TargetType="{x:Type ToggleButton}" BasedOn="{StaticResource BaseButtonStyle}">
        <Setter Property="local:ButtonProperties.MyForegroundColor" Value="Red" />
        <Setter Property="local:ButtonProperties.Data" Value="{StaticResource Arc0}" />
        <Setter Property="local:ButtonProperties.Fill" Value="LightGreen"/>
    </Style>
    <Style x:Key="ModifiedButtonStyle2" TargetType="{x:Type ToggleButton}" BasedOn="{StaticResource BaseButtonStyle}">

        <Setter Property="local:ButtonProperties.Data" Value="{StaticResource Arc90}" />
        <Setter Property="local:ButtonProperties.Fill" Value="LightCoral"/>
    </Style>

Generic.xaml -- 在自定义控件 RingControl 中使用 ModifiedButtonStyles

 <Style TargetType="{x:Type local:RingButtons2}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type local:RingButtons2}">
                <Border Background="{TemplateBinding Background}"
                        BorderBrush="{TemplateBinding BorderBrush}"
                        BorderThickness="{TemplateBinding BorderThickness}">

                    <Viewbox>
                        <Grid>
                            <!--Outer Rim -->
                            <Path Data="{StaticResource OuterRim}"  Fill="Silver" Stroke="Black" />
                            <Path Data="{StaticResource OuterWheelBackground}" Fill="White" Stroke="Black" />

                            <ToggleButton x:Name="PART_Button1" Style="{StaticResource ModifiedButtonStyle1}"/>
                            <ToggleButton x:Name="PART_Button2" Style="{StaticResource ModifiedButtonStyle2}"/>
                            <ToggleButton x:Name="PART_Button3" Style="{StaticResource ModifiedButtonStyle3}"/>
  ........................................................
  </Grid>
                        </Viewbox>
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

在用户界面中使用 RingControl2：

       <w:RingButtons2/>

似乎单击 RingButtons2 控件中的任何位置只会导致第一个定义的切换按钮响应——而不是其他任何一个。

我该如何解决这个问题，以便每个切换按钮独立于其他按钮并尊重其自己的 controltemplate 触发器？

再次感谢。

编辑#2

从 BaseButtonStyle 中删除 TextBlock 定义后，

 <TextBlock Text="Some Text">
                        <TextBlock.Foreground>
                            <SolidColorBrush Color="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=(local:ButtonProperties.MyForegroundColor)}" />
                        </TextBlock.Foreground>
                    </TextBlock>

一切正常！为什么是这样？？

谢谢。

如果目标控件具有可用于这些自定义绑定的依赖项属性，则可以使用 TemplateBinding，这是一个示例：

    <Style x:Key="BaseButtonStyle" TargetType="{x:Type Button}">
        <Setter Property="Foreground" Value="Blue" />
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type Button}">
                    <TextBlock Text="Some Text" Foreground="{TemplateBinding Foreground}" />
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

    <Style x:Key="ModifiedButtonStyle" TargetType="{x:Type Button}" BasedOn="{StaticResource BaseButtonStyle}">
        <Setter Property="Foreground" Value="Red" />
    </Style>

然后你会这样引用：

<Grid>
    <Button Style="{StaticResource ModifiedButtonStyle}" />
</Grid>

但是，在您上面给出的示例中，您在模板中使用了 Path 和 Fill，我猜它们没有关联的属性。在这种情况下，您的选择是创建一个新控件并将这些属性添加到其中，或者最好使用附加属性。在后者的情况下，您将创建一个像这样的附加属性：

public static class ButtonProperties
{
    public static Color GetMyForegroundColor(DependencyObject obj)
    {
        return (Color)obj.GetValue(MyForegroundColorProperty);
    }

    public static void SetMyForegroundColor(DependencyObject obj, Color value)
    {
        obj.SetValue(MyForegroundColorProperty, value);
    }

    // Using a DependencyProperty as the backing store for MyForegroundColor.  This enables animation, styling, binding, etc...
    public static readonly DependencyProperty MyForegroundColorProperty =
        DependencyProperty.RegisterAttached("MyForegroundColor", typeof(Color), typeof(ButtonProperties), new PropertyMetadata(Colors.Black));
}

然后你会在你的 XAML 中像这样引用并覆盖它：

<Style x:Key="BaseButtonStyle" TargetType="{x:Type Button}">
    <Setter Property="behaviors:ButtonProperties.MyForegroundColor" Value="Blue"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Button}">
                <TextBlock Text="Some Text">
                    <TextBlock.Foreground>
                        <SolidColorBrush Color="{Binding RelativeSource={RelativeSource TemplatedParent},
                            Path=(behaviors:ButtonProperties.MyForegroundColor)}" />
                    </TextBlock.Foreground>
                </TextBlock>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

<Style x:Key="ModifiedButtonStyle" TargetType="{x:Type Button}" BasedOn="{StaticResource BaseButtonStyle}">
    <Setter Property="behaviors:ButtonProperties.MyForegroundColor" Value="Red" />
</Style>

这些或多或少是相同的，只是在第一种情况下，您正在使用控件中已经存在的属性（或创建具有它们的新控件），而在第二种情况下，您声明并将它们附加到外部现有的控制。
