WPF功能强大，但是控件的用法与Winfrom不大一样。这个文件主要说明了Button控件的用法。希望能给大家一个启示。

1、按钮加入图片

        <Button Grid.Row="0" Grid.Column="0"  ToolTip="Set_Label" Name="set_label1" Height="45" VerticalAlignment="Stretch" Width="45" HorizontalAlignment="Stretch">
            <Image Source="Resources/Player1.png" StretchDirection="DownOnly" Stretch="Fill" />
        </Button>

图片的处理：

准备素材
打开Properties\Resources.resx，添加
素材属性的生成操作：Resources
引用：<Image Source="Resources/Player1.png" />

2、窗体的xaml文件中直接使用模板

        <Button  Grid.Row="0" Grid.Column="1"  x:Name="m_HelpButton" IsEnabled="True" Width="50" Height="50">
            <Button.Template>
                <ControlTemplate>
                    <Border BorderBrush="Aqua" Background="#FFEDF961">
                        <Grid>
                            <Image Margin="2" Source="Resources/Player1.png" />
                        </Grid>
                    </Border>
                </ControlTemplate>
            </Button.Template>
        </Button>

3、使用样式

<Button Grid.Row="0" Grid.Column="2" Content="播放" Height="31"  Name="button1" Foreground="#FFDE4747" Focusable="True" BorderBrush="{x:Null}" BorderThickness="0" Style="{StaticResource ButtonLeft}" Margin="106,47,82,61"/>

App.xaml中定义样式

        <Style x:Key="ButtonLeft" TargetType="{x:Type Button}">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type Button}">
                        <StackPanel Orientation="Horizontal">
                            <Image Name="minBtn" Source="Resources\player0.png" />
                            <TextBlock Text="{TemplateBinding Content}" VerticalAlignment="Center" FontSize="24"></TextBlock>
                        </StackPanel>
                        <ControlTemplate.Triggers>
                            <Trigger Property="IsMouseOver" Value="True">
                                <Setter Property="Source" Value="Resources\player1.png" TargetName="minBtn" />
                            </Trigger>
                            <Trigger Property="IsPressed" Value="True">
                                <Setter Property="Source" Value="Resources\pause0.png" TargetName="minBtn" />
                            </Trigger>
                        </ControlTemplate.Triggers>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>

4、鼠标覆盖变淡

        <Button Name="Add"  Margin="2"
            Grid.Row="1" Grid.Column="0"
            Style="{StaticResource Button_Menu}" Background="#FFEE2424" BorderBrush="#FF0031FF">
            <Image Source="/Resources/pause0.png" />
        </Button>

样式：

        <Style x:Key="Button_Menu" TargetType="{x:Type Button}">
            <Setter Property="Width" Value="50" />
            <Setter Property="Height" Value="50" />
            <Setter Property="BorderThickness" Value="0" />
            <Setter Property="Foreground" Value="Black"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type Button}">
                        <Border x:Name="MyBackgroundElement" BorderBrush="{DynamicResource ForgroundBrush}" BorderThickness="0">
                            <ContentPresenter x:Name="ButtonContentPresenter" VerticalAlignment="Center" HorizontalAlignment="Center"/>
                        </Border>
                        <ControlTemplate.Triggers>
                            <Trigger Property="IsMouseOver" Value="True">
                                <Setter TargetName="MyBackgroundElement" Property="Background" Value="{DynamicResource ForgroundBrush100}"/>
                                <Setter TargetName="MyBackgroundElement" Property="Opacity" Value="0.7"/>
                            </Trigger>
                        </ControlTemplate.Triggers>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
            <Setter Property="Cursor" Value="Hand" />
        </Style>

5、三态按钮及阴影效果

        <Button Grid.Row="1" Grid.Column="1" Content="button" Height="50" Width="50" RenderTransformOrigin="-4.5,-1.24">
            <Button.Template>
                <ControlTemplate TargetType="{x:Type Button}">
                    <Border BorderBrush="{TemplateBinding Control.BorderBrush}" BorderThickness="0" CornerRadius="3,13,3,13" Name="PART_Background">
                        <Border.Background>
                            <LinearGradientBrush EndPoint="0,1" StartPoint="0,0">
                                <GradientStop Color="White" Offset="0.0" />
                                <GradientStop Color="Silver" Offset="0.5" />
                                <GradientStop Color="White" Offset="0.0" />
                            </LinearGradientBrush>
                        </Border.Background>
                        <ContentPresenter Content="{TemplateBinding ContentControl.Content}" HorizontalAlignment="Center" VerticalAlignment="Center" />
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="UIElement.IsMouseOver" Value="True">
                            <Setter Property="Border.Background" TargetName="PART_Background">
                                <Setter.Value>
                                    <LinearGradientBrush EndPoint="0,1" StartPoint="0,0">
                                        <GradientStop Color="Silver" Offset="0.0" />
                                        <GradientStop Color="White" Offset="0.5" />
                                        <GradientStop Color="Silver" Offset="0.0" />
                                    </LinearGradientBrush>
                                </Setter.Value>
                            </Setter>
                        </Trigger>
                        <Trigger Property="ButtonBase.IsPressed" Value="True">
                            <Setter Property="UIElement.Effect">
                                <Setter.Value>
                                    <DropShadowEffect BlurRadius="10" Color="Black" Direction="0" Opacity="0.6" RenderingBias="Performance" ShadowDepth="0" />
                                </Setter.Value>
                            </Setter>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Button.Template>
        </Button>

6、三态按钮及背景色、文字颜色变化

        <Style x:Key="Style.OkOperationButton" TargetType="ButtonBase">
            <Setter Property="Width" Value="110" />
            <Setter Property="Height" Value="44" />
            <Setter Property="FontSize" Value="24" />
            <Setter Property="Background" Value="#FF0087FF" />
            <Setter Property="HorizontalContentAlignment" Value="Center" />
            <Setter Property="VerticalContentAlignment" Value="Center" />
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type ButtonBase}">
                        <Border x:Name="Border" Width="{TemplateBinding Width}"
                                Height="{TemplateBinding Height}"
                                CornerRadius="22" Background="{TemplateBinding Background}">
                            <TextBlock x:Name="TextBlock"
                                       Text="{TemplateBinding Content}"
                                       FontSize="{TemplateBinding FontSize}"
                                       HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
                                       VerticalAlignment="{TemplateBinding VerticalContentAlignment}" />
                        </Border>
 
                        <ControlTemplate.Triggers>
                            <Trigger Property="IsMouseOver" Value="True">
                                <Setter Property="Background"
                                        Value="#FF888888" />
                                <Setter TargetName="TextBlock" Property="Foreground" Value="#FF111111" />
                            </Trigger>
                            <Trigger Property="IsPressed" Value="True">
                                <Setter Property="Background"
                                        Value="#FFfcac1c" />
                                <Setter TargetName="TextBlock" Property="Foreground" Value="#FFFFFFFF" />
                            </Trigger>
                            <Trigger Property="IsEnabled" Value="False">
                                <Setter TargetName="Border" Property="Background" Value="#4D0087FF" />
                                <Setter TargetName="TextBlock" Property="Foreground" Value="#4DFFFFFF" />
                            </Trigger>
                        </ControlTemplate.Triggers>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>

提示：TemplateBinding用来实现引用时给控件复制

如：

Text="{TemplateBinding Content}"，使用：Content="确定"

FontSize="{TemplateBinding FontSize}" 使用：FontSize="18"

7、自定义控件

（1）解决方案→添加新建项→自定义控件（WPF）

（2）CustomControl.cs

using System;
……
using Button = System.Windows.Controls.Button;
 
namespace StudentImages
{
    
    public class CustomControl : Button
    {
        static CustomControl()
        {
            DefaultStyleKeyProperty.OverrideMetadata(typeof(CustomControl), new FrameworkPropertyMetadata(typeof(CustomControl)));
        }
 
        public ImageSource Icon
        {
            get
            {
                return (ImageSource)GetValue(IconProperty);
            }
            set { SetValue(IconProperty, value); }
        }
         
        public static readonly DependencyProperty IconProperty
            = DependencyProperty.Register("Icon", typeof(ImageSource), typeof(CustomControl), null);
 
        …………
    }
}

说明：

namespace StudentImages

命名空间，自动生成

public class CustomControl : Button

CustomControl控件名称，自动生成

Button是继承的类，这里手工修改，否则这个自定义控件将会没有按钮的一些属性、事件

Icon是属性的名称

ImageSource是属性的类型

（3）Themes\Generic.xaml

    <Style TargetType="{x:Type local:CustomControl}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type local:CustomControl}">
                    <Border Background="{TemplateBinding Background}"
                            BorderBrush="{TemplateBinding BorderBrush}"
                            BorderThickness="{TemplateBinding BorderThickness}">
                        <Grid>
                            <Border x:Name="PART_Border" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" />
                            <Grid HorizontalAlignment="Center"  VerticalAlignment="Center">
                                <StackPanel>
                                    <Grid HorizontalAlignment="Center" VerticalAlignment="Center">
                                        <Image x:Name="PART_Icon" Source="{TemplateBinding Icon}" Width="50" Height="50"/>
                                        <Image x:Name="PART_MouseOverIcon" Visibility="Collapsed" Source="{TemplateBinding IconMouseOver}" Width="50" Height="50"/>
                                        <Image x:Name="PART_PressIcon" Visibility="Collapsed" Source="{TemplateBinding IconPress}"  Width="50" Height="50"/>           
                                    </Grid>
                                </StackPanel>
                            </Grid>
                        </Grid>
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsMouseOver" Value="True">
                            <Setter Property="Background" TargetName="PART_Border" Value="{Binding MouseOverBackground,RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type local:CustomControl}}}"/>
                            <Setter Property="BorderBrush" TargetName="PART_Border" Value="{Binding MouseOverBorderBrush,RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type local:CustomControl}}}"/>
                            <Setter Property="Visibility" TargetName="PART_MouseOverIcon" Value="Visible"/>
                            <Setter Property="Visibility" TargetName="PART_Icon" Value="Collapsed"/>
                            <Setter Property="Visibility" TargetName="PART_PressIcon" Value="Collapsed"/>
                        </Trigger>
                        <Trigger Property="IsPressed" Value="True">
                            <Setter Property="Background" TargetName="PART_Border" Value="{Binding MouseDownBackground,RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type local:CustomControl}}}"/>
                            <Setter Property="BorderBrush" TargetName="PART_Border" Value="{Binding MouseDownBorderBrush,RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type local:CustomControl}}}"/>
                            <Setter Property="Visibility" TargetName="PART_PressIcon" Value="Visible"/>
                            <Setter Property="Visibility" TargetName="PART_Icon" Value="Collapsed"/>
                            <Setter Property="Visibility" TargetName="PART_MouseOverIcon" Value="Collapsed"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

{TemplateBinding xxx}

xxx：如果是原属性，这里直接使用；如果是自定义的，需要在cs文件中注册
