Silverlight 用DependencyProperty 自定义ImageButton控件 定义属性

为ImageButton自定义IconSource和Contents属性

xaml代码

<UserControl x:Class="SilverlightCreate.SilverlightButtons"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    d:DesignHeight="30" d:DesignWidth="100">

    <Grid x:Name="LayoutRoot" Background="Transparent">
        <StackPanel x:Name="myButton" Orientation="Horizontal" >
            <Image x:Name="myImg" Stretch="None"  />
            <TextBlock x:Name="myText" VerticalAlignment="Center" FontSize="13" Padding="5" />
        </StackPanel>
        <Rectangle x:Name="myRectangle" Margin="-3" />
    </Grid>
</UserControl>

下面开始自定义属性内容，自定义属性要用 依赖属性类 DependencyProperty

public static readonly DependencyProperty MyPropertyProperty =
            DependencyProperty.Register("MyProperty", typeof(int), typeof(ownerclass), new UIPropertyMetadata(0));

DependencyProperty 的Register 方法中有四个参数，第一个是自定的属性，第二个自定义属性的参数类型，第三个是自定义属性所属类，第四个是属性元数据的实例，参数类型是PropertyMetadata。

使用vs2010的小技巧，生成依赖属性可以输入propdp，然后按两下Tab键，就会自动生成如下代码

            }
        }
        
    }
}

自定义控件做好后就可以运用该控件了，如下图，鼠标移上去会出现边框
