Tip - Silverlight/WPF: 控件继承

很常用的代码重构：多个控件有相同的功能时，一般抽象一个基类，将相同的功能提到基类里，控件继承自这个基类。Silverlight中实现时，遇到了一个小麻烦：设计器自动生成的代码总是报错

如下是继承自ProtectedView的在子类TipsView的code behind代码：

Partial Public Class TipsView@H_801_29@     Inherits ProtectedView

    ...

End Class

还需在TipsView的xaml中做如下改动：

<@H_615_42@myApp:ProtectedView x:Class="MyAppNamespace.TipsView"@H_801_29@            xmlns="http://scheR_534_11845@as.microsoft.com/winfx/2006/xaml/presentation" @H_801_29@            xmlns:x="http://scheR_534_11845@as.microsoft.com/winfx/2006/xaml" @H_801_29@            xmlns:d="http://scheR_534_11845@as.microsoft.com/expression/blend/2008"@H_801_29@            xmlns:mc="http://scheR_534_11845@as.openxmlformats.org/markup-compatibility/2006"@H_801_29@            mc:Ignorable="d"@H_801_29@            xmlns:navigation="clr-namespace:Sy@L_673_9@.Windows.Controls;assembly=Sy@L_673_9@.Windows.Controls.Navigation"@H_801_29@            d:DesignWidth="640" d:DesignHeight="480"@H_801_29@            xmlns:MyApp="clr-namespace:MyAppNamespace" @H_801_29@            title="">@H_801_29@@H_801_29@     <Grid>@H_801_29@        @H_801_29@     </Grid>

@H_801_29@ </MyApp:ProtectedView>   

WPF的继承同样适用于 - http://geekswithblogs.net/lbugnion/archive/2007/03/02/107747.aspx
