[英]How to use BasedOn to template a toggle button in Generic.xaml?
WPF的C#XAML
在我的Generic.xaml中,我有多種形式的樣式:
<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>
所有這些切換按鈕之間的唯一區別是路徑定義和填充顏色。
是否可以僅需要提供路徑和填充顏色的方式對這種樣式進行模板化/簡化?
這與以下內容類似:
<Style x:Key="ToggleButtonStyle12" BasedOn(??????)>
<Setter Property = "Path" Value="InsideQuarter3"/>
<Setter Property = "Fill" Value="DarkOrange"/>
</Style>
感謝您的任何幫助。
編輯#1好吧,我以為自己有錯–我錯了。 下面的代碼將正確設置“路徑數據”和“填充”屬性。 但是,只有第一個創建的ToggleButton會保留“ MouseOver”和其他ControlTemplate.Triggers。 我需要RingControl中的所有切換按鈕都尊重自己的觸發器。
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>
</TextBlock>
<Path x:Name="path1" Data="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=(local:ButtonProperties.Data)}"

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"/>
</Style>
<Style x:Key="ModifiedButtonStyle3" TargetType="{x:Type ToggleButton}" BasedOn="{StaticResource BaseButtonStyle}">
<Setter Property="local:ButtonProperties.MyForegroundColor" Value="Red" />
<Setter Property="local:ButtonProperties.Data" Value="{StaticResource Arc90}" />
<Setter Property="local:ButtonProperties.Fill" Value="LightCoral"/>
</Style>
Generic.xaml-在自定義控件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>
在用戶界面中使用RingControl2:
<w:RingButtons2/>
似乎單擊RingButtons2控件中的任何位置只會導致第一個定義的切換按鈕做出響應-不會產生任何其他響應。
我該如何解決這個問題,以使每個切換按鈕都獨立於其他按鈕運行,並尊重自己的控制模板觸發器?
再次感謝。
編輯#2
從BaseButtonStyle刪除TextBlock定義后,
<TextBlock Text="Some Text">
<TextBlock.Foreground>
<SolidColorBrush Color="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=(local:ButtonProperties.MyForegroundColor)}" />
</TextBlock.Foreground>
</TextBlock>
所有工作! 為什么是這樣??
謝謝。
如果目標控件具有可用於這些自定義綁定的依賴項屬性,則可以使用TemplateBinding,這是一個示例:
<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>
然后您將這樣引用:
<Grid>
<Button Style="{StaticResource ModifiedButtonStyle}" />
</Grid>
但是,在上面給出的示例中,您正在模板中使用“路徑”和“填充”,我想它們沒有關聯的屬性。 在這種情況下,您的選擇是創建一個新控件並向其中添加這些屬性,或者最好使用附加屬性。 對於后者,您將創建一個如下所示的附加屬性:
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中引用並覆蓋它:
<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>
這些大致相同,只是在第一種情況下,您使用控件中已經存在的現有屬性(或創建一個包含它們的新控件),而在第二種情況下,您聲明並將它們附加到外部現有的控件。
