我想根據屬性在WPF中的兩種樣式之間切換。 要在每個樣式中使用ControlTemplate的樣式和在ControlTemplates之間切換的觸發器之間切換樣式。 我的問題是，我有一個ContentPresenter內每個基本風格，我不能從外部（從用途）設置它。WPF：如何通過樣式和ControlTemplate之間的內容屬性
這是我在XAML代碼：
<Style x:Key="SecondaryButtonStyle" TargetType="{x:Type Button}">
<Setter Property="Background" Value="{StaticResource GrayButtonNormalBackground}"/>
<Setter Property="BorderBrush" Value="Transparent"/>
<Setter Property="BorderThickness" Value="2"/>
<Setter Property="Foreground" Value="#FF494F5A"/>
<Setter Property="FontSize" Value="24.5" />
<Setter Property="FontWeight" Value="Bold" />
<Setter Property="HorizontalContentAlignment" Value="Center"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="MinHeight" Value="76" />
<Setter Property="Padding" Value="10,0,10,0"/>
<Setter Property="Effect" Value="{StaticResource ButtonEffect}"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Background="{TemplateBinding Background}" CornerRadius="5,5,5,5"
BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" >
<Grid>
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}"
RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Grid>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="{StaticResource GrayButtonMouseOverBackground}" />
</Trigger>
<Trigger Property="IsPressed" Value="True">
<Setter Property="Background" Value="{StaticResource GrayButtonIsPressedBackground}" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<Style x:Key="SecondaryButtonWithArrowStyle" TargetType="{x:Type Button}">
<Setter Property="Background" Value="{StaticResource GrayButtonNormalBackground}"/>
<Setter Property="BorderBrush" Value="Transparent"/>
<Setter Property="BorderThickness" Value="2"/>
<Setter Property="Foreground" Value="#FF494F5A"/>
<Setter Property="FontSize" Value="24.5" />
<Setter Property="FontWeight" Value="Bold" />
<Setter Property="HorizontalContentAlignment" Value="Center"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="MinHeight" Value="76" />
<Setter Property="Padding" Value="20,0"/>
<Setter Property="Effect" Value="{StaticResource ButtonEffect}"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Background="{TemplateBinding Background}" CornerRadius="5,32,32,5"
BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" >
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid Grid.Column="0" HorizontalAlignment="Left" VerticalAlignment="Center" Margin="12,4,0,4">
<Path Data="F1M46,23.478C46,10.512 35.704,0 23,0 10.299,0 0,10.512 0,23.478 0,36.44 10.299,46.951 23,46.951 35.704,46.951 46,36.44 46,23.478"
Fill="#FF646A74" x:Name="Path"/>
<Path Data="F1M12.504,9.03L9.823,9.028 5.15,9.025 12.273,1.903 10.369,0 1.903,8.466 0,10.369 10.369,20.739 12.273,18.836 5.144,11.706 9.822,11.709 12.502,11.711 20.912,11.715 20.913,9.035z"
Fill="White" HorizontalAlignment="Center" VerticalAlignment="Center" />
</Grid>
<ContentPresenter Grid.Column="1" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}"
RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Grid>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="{StaticResource GrayButtonMouseOverBackground}" />
</Trigger>
<Trigger Property="IsPressed" Value="True">
<Setter Property="Background" Value="{StaticResource GrayButtonIsPressedBackground}" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<ControlTemplate x:Key="NormalButton">
<Button Style="{StaticResource SecondaryButtonStyle}" />
</ControlTemplate>
<ControlTemplate x:Key="ArrowButton">
<Button Style="{StaticResource SecondaryButtonWithArrowStyle}" />
</ControlTemplate>
<Style x:Key="SwitchButtonStyle" TargetType="{x:Type Button}">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="False">
<Setter Property="Template" Value="{StaticResource NormalButton}" />
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Template" Value="{StaticResource ArrowButton}" />
</Trigger>
</Style.Triggers>
</Style>
用法是：
<Button Style="{StaticResource SwitchButtonStyle}" Content="Back" HorizontalAlignment="Center" VerticalAlignment="Center" />
我怎樣才能讓按鈕拍攝Content="Back"？
謝謝！

那麼既然你有不同的風格，無論如何，我認爲你的condition在某些時候是一個布爾值，爲什麼不只是用可見性和轉換器交換單獨的按鈕，而不是在同一個對象上交換樣式的所有內容？性能明智，它會更有意義。 –
感謝您的回答，但是我們考慮了一下，並對未來有了一個總結，如果我們需要5種不同樣式的enum屬性而不是bool - 觸發器使得它更易於使用，並且沒有轉換器需要。 –
