Wpf XAML创建按钮模板

我在XAML中创建了一个自定义外观按钮，其定义如下：

<Button Margin="10,30,10,10" Height="100" Grid.Column="1" Command="{Binding HelpCommand}">
                <Button.Template>
                    <ControlTemplate>
                        <Border x:Name="Overlay" CornerRadius="15" Background="#4F81BD">
                            <TextBlock Foreground="Black" 
                                       Text="Help"
                                       HorizontalAlignment="Center"
                                       VerticalAlignment="Center"
                                       FontSize="26"/>
                        </Border>
                        <ControlTemplate.Triggers>
                            <Trigger Property="IsEnabled" Value="false">
                                <Setter TargetName="Overlay" Property="Background" Value="#FF008DCF"/>
                                <Setter TargetName="Overlay" Property="BorderBrush" Value="#FF1BB7FF"/>
                                <Setter TargetName="Overlay" Property="BorderThickness" Value="2"/>
                            </Trigger>
                            <Trigger Property="IsEnabled" Value="true">
                                <Setter TargetName="Overlay" Property="BorderBrush" Value="Black"/>
                                <Setter TargetName="Overlay" Property="BorderThickness" Value="2"/>
                            </Trigger>
                            <Trigger Property="IsMouseOver" Value="true">
                                <Setter TargetName="Overlay" Property="BorderThickness" Value="3"/>
                                <Setter TargetName="Overlay" Property="Background" Value="#FF44C3FF"/>
                            </Trigger>
                        </ControlTemplate.Triggers>
                    </ControlTemplate>
                </Button.Template>
            </Button>

如何实现此目的？

您必须设置样式并将其保存在单独的.xaml文件中，然后为完整的应用程序或要使用它的每个控件/窗口加载它

这是我举的一个例子，你可以改变它并使用它

<Style x:Key="DefBtn" TargetType="{x:Type Button}">
    <Setter Property="Background" Value="#EBEBEB"/>
    <Setter Property="BorderBrush" Value="#8C8C8C"/>
    <Setter Property="BorderThickness" Value="1"/>
    <Setter Property="Foreground" Value="Black"/>
    <Setter Property="FontSize" Value="12"/>
    <Setter Property="FontFamily" Value="Segoe UI regular"/>
    <Setter Property="VerticalContentAlignment" Value="Center"/>
    <Setter Property="HorizontalContentAlignment" Value="Center"/>
    <Setter Property="Padding" Value="3,2"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Button">
                <Border Name="border" 
                    BorderThickness="{TemplateBinding BorderThickness}"
                    Padding="{TemplateBinding Padding}" 
                    BorderBrush="{TemplateBinding BorderBrush}" 
                    CornerRadius="1" 
                    Background="{TemplateBinding Background}">
                    <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" 
                                  VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

现在，您可以更改名称并将其作为资源字典添加到项目中。 当你想加载它时，你可以这样做

<Window.Resources>
        <ResourceDictionary Source="pack://application:,,,/SomeName;component/NameOfYourXamlFile.xaml"/>
 </Window.Resources>

    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Button">
                <Border Name="border" 
                    BorderThickness="{TemplateBinding BorderThickness}"
                    Padding="{TemplateBinding Padding}" 
                    BorderBrush="{TemplateBinding BorderBrush}" 
                    CornerRadius="1" 
                    Background="{TemplateBinding Background}">
                    <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" 
                                  VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

现在，您可以更改名称并将其作为资源字典添加到项目中。 当你想加载它时，你可以这样做

<Window.Resources>
        <ResourceDictionary Source="pack://application:,,,/SomeName;component/NameOfYourXamlFile.xaml"/>
 </Window.Resources>

首先，您必须在字典文件中声明您的样式

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

    <Style x:Key="CompIconButton" TargetType="Button">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                <!--Anything-->
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</ResourceDictionary>

然后，您需要在应用程序的资源中声明此字典

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="Generic_UI/Buttons_Resources.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

您最终将能够按照预期使用您的按钮样式

<Button Click="Button_Click" Style="{StaticResource CompIconButton}"/>

分配

控制模板

一个

x:Key

并将其移动到您的

App.xaml

文件：

<Application x:Class="WpfApplication1.App"

             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             StartupUri="MainWindow.xaml">
    <Application.Resources>
        <ResourceDictionary>
            <ControlTemplate x:Key="MyButtonTemplate">
                <Border x:Name="Overlay" CornerRadius="15" Background="#4F81BD">
                    <TextBlock Foreground="Black"

                                       FontSize="26"/>
                </Border>
                <ControlTemplate.Triggers>
                    <Trigger Property="IsEnabled" Value="false">
                        <Setter TargetName="Overlay" Property="Background" Value="#FF008DCF"/>
                        <Setter TargetName="Overlay" Property="BorderBrush" Value="#FF1BB7FF"/>
                        <Setter TargetName="Overlay" Property="BorderThickness" Value="2"/>
                    </Trigger>
                    <Trigger Property="IsEnabled" Value="true">
                        <Setter TargetName="Overlay" Property="BorderBrush" Value="Black"/>
                        <Setter TargetName="Overlay" Property="BorderThickness" Value="2"/>

                        <Setter TargetName="Overlay" Property="Background" Value="#FF44C3FF"/>
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>

        </ResourceDictionary>
    </Application.Resources>
</Application>

您可以对

样式

（而不是

控制模板

）执行相同的操作。

将

分配到
