如何使用BasedOn在Generic.xaml中设置切换按钮的模板?

[英]How to use BasedOn to template a toggle button in Generic.xaml?

WPF的C#XAML

在我的Generic.xaml中,我有多种形式的样式:

  <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?

这与以下内容类似:

<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,我以为自己有错–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会保留“ MouseOver”和其他ControlTemplate.Triggers。 我需要RingControl中的所有切换按钮都尊重自己的触发器。

  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">

                                          SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                    </Grid>

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.MyForegroundColor" Value="Red" />
        <Setter Property="local:ButtonProperties.Data" Value="{StaticResource Arc45}" />
        <Setter Property="local:ButtonProperties.Fill" Value="LightPink"/>

        <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做出响应-不会产生任何其他响应。

我该如何解决这个问题,以使每个切换按钮都独立于其他按钮运行,并尊重自己的控制模板触发器?

再次感谢。

编辑#2

从BaseButtonStyle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>

所有工作! 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>

然后您将这样引用:

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

但是,在上面给出的示例中,您正在模板中使用“路径”和“填充”,我想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向其中添加这些属性,或者最好使用附加属性。 对于后者,您将创建一个如下所示的附加属性:

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));
}

然后在XAML中引用并覆盖它:

<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>

这些大致相同,只是在第一种情况下,您使用控件中已经存在的现有属性(或创建一个包含它们的新控件),而在第二种情况下,您声明并将它们附加到外部现有的控件。
