Silverlightbutton图片切换样式实例代码

之前一直做WPF现在开始接触Slilverlight感触很多。

今天做一个Button要求

有两个图片，button默认有一个图片，鼠标over时用另一个图片，

用wpf做的时候写一个template很简单，但silverlight和wpf写起来不一样

记录一下。大概思路是两个image鼠标MouseOver的时候一个Visible一个Collapsed

写的是一个自定义控件，代码和皮肤分离，很简单的一个demo

代码下载：ImageButtonTest.rar

先写一个继承自button的imagebutton类

namespace ImageButtonTest
{
    /// <summary>
    /// build by lp
    /// </summary>
    public class MyImageButton : Button
    {

        public static readonly DependencyProperty ImageNormalProperty =
            DependencyProperty.Register("ImageNormal",
                                        typeof(ImageSource),
                                        typeof(MyImageButton),
                                        new PropertyMetadata(null));

        public static readonly DependencyProperty ImageHoverProperty =
            DependencyProperty.Register("ImageHover",
                                        typeof(ImageSource),
                                        typeof(MyImageButton),
                                        new PropertyMetadata(null));
        //鼠标移到上面
        public ImageSource ImageHover
        {
            get { return (ImageSource)GetValue(ImageHoverProperty); }
            set { SetValue(ImageHoverProperty, value); }
        }
        //默认图片
        public ImageSource ImageNormal
        {
            get { return (ImageSource)GetValue(ImageNormalProperty); }
            set { SetValue(ImageNormalProperty, value); }
        }

        public MyImageButton()
        {
            this.DefaultStyleKey = typeof(MyImageButton);
        }
    }
}
</div>

一个是鼠标移到上面的imageSource一个是默认的source

看一下它的样式 用sotryboard控制

鼠标MouseOver的时候一个Visible一个Collapsed

    <Style TargetType="local:MyImageButton">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="local:MyImageButton">
                    <Grid Background="{TemplateBinding Background}">
                        <VisualStateManager.VisualStateGroups>
                            <VisualStateGroup x:Name="CommonStates">

                                <VisualState x:Name="Normal"/>
                                <VisualState x:Name="MouseOver">
                                    <Storyboard>
                                        <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="mouseOverImage">
                                            <DiscreteObjectKeyFrame KeyTime="0">
