WPF 自定义 ImageButton

控件源码：

public class ImageButton : Button
    {
        public ImageButton() {
        }

public string NoramlImgPath
        {
            get { return (string)GetValue(NoramlImgPathProperty); }
            set { SetValue(NoramlImgPathProperty, value); }
        }

public string HoverImgPath
        {
            get { return (string)GetValue(HoverImgPathProperty); }
            set { SetValue(HoverImgPathProperty, value); }
        }

public string DisableImgPath
        {
            get { return (string)GetValue(DisableImgPathProperty); }
            set { SetValue(DisableImgPathProperty, value); }
        }

public static readonly DependencyProperty NoramlImgPathProperty =
    DependencyProperty.Register(
    "NoramlImgPath",
    typeof(string),
    typeof(ImageButton),
    new PropertyMetadata(""));

public static readonly DependencyProperty HoverImgPathProperty =
    DependencyProperty.Register(
    "HoverImgPath",
    typeof(string),
    typeof(ImageButton),
    new PropertyMetadata(""));

public static readonly DependencyProperty DisableImgPathProperty =
    DependencyProperty.Register(
    "DisableImgPath",
    typeof(string),
    typeof(ImageButton),
    new PropertyMetadata(""));
    }

Style:资源文件里需要引用控件Namespace

<SolidColorBrush x:Key="MouseOverBorderBrush" Color="#2D2F3D" />
<SolidColorBrush x:Key="buttonDisableBackground" Color="#222732"/>

        <Setter Property="BorderThickness" Value="1"/>
        <Setter Property="BorderBrush" Value="Transparent"/>
        <Setter Property="Template" >
            <Setter.Value>
                <ControlTemplate  TargetType="{x:Type local:ImageButton}">
                    <Border x:Name="border" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}"  Width="{TemplateBinding Width}" Height="{TemplateBinding Height}"    SnapsToDevicePixels="True">

        </Setter>

使用：

xmlns:shared="clr-namespace:Shared.Controls;assembly=Shared"

<shared:ImageButton   Width="24"  Height="24"  Margin="0 5" Command="{Binding SaveImageCommand}"
                                               NoramlImgPath="../Images/export_image.png"
                                               HoverImgPath="../Images/export_image_hover.png"  
                                               Style="{StaticResource imageButtonStyle}" ></shared:ImageButton>
