本文实例为大家分享了WPF图片按钮的实现代码，供大家参考，具体内容如下

直接代码

public class ImageButton : System.Windows.Controls.Button
 {

 /// <summary>
 /// 图片
 /// </summary>
 public static readonly DependencyProperty ImageProperty = DependencyProperty.Register("Image",typeof(ImageSource),typeof(ImageButton),new PropertyMetadata(null));

 /// <summary>
 /// 图片的宽度
 /// </summary>
 public static readonly DependencyProperty ImageWidthProperty = DependencyProperty.Register("ImageWidth",typeof(double),new PropertyMetadata(double.NaN));

 /// <summary>
 /// 图片的高度
 /// </summary>
 public static readonly DependencyProperty ImageHeightProperty = DependencyProperty.Register("ImageHeight",new PropertyMetadata(double.NaN));

 /// <summary>
 /// 构造函数
 /// </summary>
 static ImageButton()
 {
  DefaultStyleKeyProperty.OverrideMetadata(typeof(ImageButton),new System.Windows.FrameworkPropertyMetadata(typeof(ImageButton)));
 }

 /// <summary>
 /// 设置图片
 /// </summary>
 public ImageSource Image
 {
  get
  {
  return GetValue(ImageProperty) as ImageSource;
  }
  set
  {
  SetValue(ImageProperty,value);
  }
 }

 /// <summary>
 /// 图片宽度(属性)
 /// </summary>
 public double ImageWidth
 {
  get
  {
  return (double)GetValue(ImageWidthProperty);
  }
  set
  {
  SetValue(ImageWidthProperty,value);
  }
 }

 /// <summary>
 /// 图片高度(属性)
 /// </summary>
 public double ImageHeight
 {
  get
  {
  return (double)GetValue(ImageHeightProperty);
  }
  set
  {
  SetValue(ImageHeightProperty,value);
  }
 }

 }

样式代码

<Style TargetType="{x:Type xi:ImageButton}">
 <Setter Property="Template">
  <Setter.Value>
  <ControlTemplate TargetType="{x:Type xi:ImageButton}">
   <Grid>
   <Grid.RowDefinitions>
    <RowDefinition Height="*"/>
    <RowDefinition Height="Auto"/>
   </Grid.RowDefinitions>
   <Border x:Name="border" Grid.RowSpan="2" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" 
    SnapsToDevicePixels="true" CornerRadius="3,3,3"/>
   <Image Grid.Row="0" Source="{TemplateBinding Image}"
     Width="{TemplateBinding ImageWidth}"
     Height="{TemplateBinding ImageHeight}"
     VerticalAlignment="{TemplateBinding VerticalAlignment}"/>
   <ContentPresenter Grid.Row="1" HorizontalAlignment="Center" Margin="{TemplateBinding Padding}" 
     VerticalAlignment="Center" RecognizesAccessKey="True" />
   </Grid>
   <ControlTemplate.Triggers>
   <Trigger Property="IsPressed" Value="True">
    <Setter Property="Foreground" Value="#999999"/>
   </Trigger>
   </ControlTemplate.Triggers>

  </ControlTemplate>
  </Setter.Value>
 </Setter>
 </Style>

调用实例

复制代码代码如下:

 <xi:ImageButton Image="../Image/设置.png" Content="新增会员" ImageHeight="52" ImageWidth="52" Width="72" Height="72" Margin="30,10,10"/>

效果展示
