学会怎样给用户提供事件接口，本例子中通过监视Dock的变化事件，让用户可以在dock变化时候，自定义下一步操作
学会如何使用C# 符合枚举，以及如何在Xaml中使用
实战AyImageButton1.2的诞生，增加纯图标或者纯文本，是否开启提示版本
难DEMO：在第三步的基础上，增加 Dock变化和RenderMode变化的混搭 DEMO
效果图：
版本记录：

版本号	状态	版本更新说明
1.0	√	完成基本图文显示混带，DOCK变化自动调整，难点IsCustomed自定义用户控件外观，用户自己定义外观
1.2	√	增加IconDockPlacementValueChanged事件:用于IconDockPlacement值变化后的客户定义操作增加IsCustomed=false纯图标显示、文本、提示、Dock值变化的混搭、暂未添加IsCustomed=true的自动调整完成
1.3	待	增加 AyImageButton容器容器控件，增加 IsPressed,IsMouseEnter,IsMouseOut,IsEnabled状态的自定义效果

AyImageButton 1.2开始继续制作

1. 给用户增加路由事件，让用户可以在Dock值变化的时候触发该事件，并简单定义个Raise

#region 提供用户截获Dock变化时候事件 2015-02-04 09:35:29   private static readonly RoutedEvent IconDockPlacementValueChangedEvent =     EventManager.RegisterRoutedEvent("IconDockPlacementValueChanged", RoutingStrategy.Bubble, typeof(RoutedPropertyChangedEventHandler<Dock>), typeof(AyImageButton));   public event RoutedPropertyChangedEventHandler<Dock> IconDockPlacementValueChanged   {    add { AddHandler(IconDockPlacementValueChangedEvent, value); }    remove { RemoveHandler(IconDockPlacementValueChangedEvent, value); }   }   private void IconDChanged(Dock oldDock, Dock newDock) {    RoutedPropertyChangedEventArgs<Dock> args = new RoutedPropertyChangedEventArgs<Dock>(oldDock, newDock);    args.RoutedEvent = AyImageButton.IconDockPlacementValueChangedEvent;    RaiseEvent(args);   }   #endregion

那么光定义是没用的，我们要在哪里调用IconDChanged方法呢？当然在IconDockPlacementProperty的回调函数IconDockPlacementChanged里面了，因为可以拿到旧值和新值

private static void IconDockPlacementChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)   {    AyImageButton aybtn = (AyImageButton)d;    Dock newDock = (Dock)e.NewValue;    //e.Property 是被修改的属性,这里就是IconDockPlacement    //调整文字摆放方式    IconDockChanged(aybtn, newDock);    if (RenderReadyed)    {     Dock oldDock = (Dock)e.OldValue;     //触发客户端定义的事件     aybtn.IconDChanged(oldDock, newDock);    }   }

OK，客户端使用

<local:AyImageButton x:Name="btnTest2" IconSource="icons/set_64.png" Background="#55B472" TextContent="AY超大按钮" IconDockPlacement="Top"   Canvas.Left="212" Canvas.Top="50"  HorizontalContentAlignment="Center" TextColor="#fff"  IsCustomed="True"  IsTabStop="False"  IconWidthHorizontal="32" IconHeightHorizontal="32"  IconWidthVertical="64" IconHeightVertical="64"  PaddingHorizontal="18,0,0,0"   WidthHorizontal="280" HeightHorizontal="80"  WidthVertical="280" HeightVertical="160"  TextFontSizeHorizontal="32" TextFontSizeVertical="48" MouseDown="btnTest2_MouseDown" IconDockPlacementValueChanged="IconDockPlacementValueChanged"  />

优化后的控件代码，去掉部分static变量，防止数量多，默认的内存占用数量

AyImageButton V1.1.9

后台代码（控件代码，由于dock默认值是Left，为了防止触发改变事件，我使用RenderReadyed控制默认显示时候不触发事件）：

public void IconDockPlacementValueChanged(object sender, RoutedPropertyChangedEventArgs<Dock> e)   {    AyImageButton aybtn = (AyImageButton)sender;    Dock nDock = (Dock)e.NewValue;    Dock oDock = (Dock)e.OldValue;    //判断 新值 把内容变为现*原* ，颜色变成其他色    aybtn.TextContent = String.Format("现{0}原{1}", nDock.ToString(), oDock.ToString());    if (nDock == Dock.Top)    {     aybtn.TextColor = new SolidColorBrush(Colors.Blue);     aybtn.TextFontSizeVertical = 20;    }    else if (nDock == Dock.Left)    {     aybtn.TextColor = new SolidColorBrush(Colors.Yellow);     aybtn.TextFontSizeHorizontal = 32;    }    else if (nDock == Dock.Right)    {     aybtn.TextColor = new SolidColorBrush(Colors.Gold);     aybtn.TextFontSizeVertical = 32;    }    else if (nDock == Dock.Bottom)    {     aybtn.TextColor = new SolidColorBrush(Colors.Pink);     aybtn.TextFontSizeVertical = 20;    }   }

效果图：加了RenderChangedEnabled属性，用来控制按钮窗体初始化时候不执行Changed事件

OK，去掉了Static的使用，增加了路由事件的使用，接下来我们增加几种显示方式，纯图标，纯文字，提示 3种RenderMode,是个多值枚举

 [Flags]  public enum AyImageButtonRenderMode  {   Icon = 1,   Text = 2,   Tips = 4  }

优化 Dock的判断if语句变成switch

AyImageButton 1.2 DEMO页面

讲解：RenderMode是个多值枚举，在xaml中使用英文的逗号隔开

效果图：

[Aaronyang] 写给自己的WPF4.5 笔记12[自定义控件-AyImageButton的过程 2/4]

=============潇洒的版权线==========www.ayjs.net===== Aaronyang ========= AY =========== 安徽六安杨洋 ========== 未经允许不许转载 =========

接下来基础工作最后一步：Render模式与Dock模式混搭，暂时只是先

我们多找几张图片64*64的。增加一个下拉框调整dock，增加一组check调整RenderMode

注意：由于我使用的是Canvas布局，checkbox的按钮事件拿到ayImageButton的控件的第一个样子，如果按钮组的代码不在checkbox组的上面，是拿不到AyImageButton控件的

<StackPanel Background="Yellow" x:Name="RenderAndDock" Canvas.Left="1385" Canvas.Top="69" >    <local:AyImageButton x:Name="rd2" IconSource="icons/point_64.png" TextColor="#fff" Background="YellowGreen"  TextContent="积分管理" IconDockPlacement="Left"         PaddingHorizontal="10,5,5,5"  HorizontalContentAlignment="Left"          WidthVertical="88" TabIndex="0"        HeightOnlyIcon="92" WidthOnlyIcon="92" IconHeightOnlyIcon="48" IconWidthOnlyIcon="48"          />    <local:AyImageButton x:Name="rd3" IconSource="icons/wjx_64.png" TextColor="#fff" Background="#86C507"  TextContent="评论管理" IconDockPlacement="Left"         PaddingHorizontal="10,5,5,5"  HorizontalContentAlignment="Left"         WidthVertical="88" TabIndex="1"          HeightOnlyIcon="92" WidthOnlyIcon="92" IconHeightOnlyIcon="48" IconWidthOnlyIcon="48"          />    <local:AyImageButton x:Name="rd4" IconSource="icons/house_64.png" TextColor="#fff" Background="YellowGreen"  TextContent="资料库" IconDockPlacement="Left"         PaddingHorizontal="10,5,5,5"  HorizontalContentAlignment="Left"         WidthVertical="88" TabIndex="2"          HeightOnlyIcon="92" WidthOnlyIcon="92" IconHeightOnlyIcon="48" IconWidthOnlyIcon="48"          />    <local:AyImageButton x:Name="rd" IconSource="icons/set_64.png" Background="#86C507" TextContent="设置" IconDockPlacement="Left"           PaddingHorizontal="10,5,5,5"  HorizontalContentAlignment="Left" TextColor="#fff"           WidthVertical="88" TabIndex="3"         HeightOnlyIcon="92" WidthOnlyIcon="92" IconHeightOnlyIcon="48" IconWidthOnlyIcon="48"          />   </StackPanel>   <StackPanel Canvas.Left="1343" Canvas.Top="18" x:Name="spRenderSelect" Orientation="Horizontal">    <CheckBox Tag="Icon" FontSize="16" IsChecked="True" Checked="CheckBox_Checked" Unchecked="CheckBox_Checked">显示图标</CheckBox>    <CheckBox Tag="Text" FontSize="16" IsChecked="True" Checked="CheckBox_Checked" Unchecked="CheckBox_Checked">显示文本</CheckBox>    <CheckBox Tag="Tips" FontSize="16" Checked="CheckBox_Checked" Unchecked="CheckBox_Checked">提示</CheckBox>   </StackPanel>   <ComboBox Canvas.Left="1206" Canvas.Top="17" Width="120" Height="20" x:Name="cboDockSelect" SelectionChanged="cboDockSelect_SelectionChanged"/>

接着，添加后台的事件，代码比较简单，不讲解了

private void cboDockSelect_SelectionChanged(object sender, SelectionChangedEventArgs e)   {    foreach (var item in RenderAndDock.Children)    {     AyImageButton ay = item as AyImageButton;     if (ay != null)     {      ay.IconDockPlacement =(Dock)cboDockSelect.SelectedItem;     }    }   }

private void CheckBox_Checked(object sender, RoutedEventArgs e)   {    CheckBox ck = (CheckBox)sender;    //强制转换枚举    AyImageButtonRenderMode mode = (AyImageButtonRenderMode)Enum.Parse(typeof(AyImageButtonRenderMode), ck.Tag.ToString());    AyImageButtonRenderMode currRenderMode = rd.RenderMode;    if (ck.IsChecked.Value)    {     foreach (var item in RenderAndDock.Children)     {      AyImageButton ay = item as AyImageButton;      if (ay != null)      {       ay.RenderMode = ay.RenderMode | mode;      }     }    }    else    {     foreach (var item in RenderAndDock.Children)     {      AyImageButton ay = item as AyImageButton;      if (ay != null)      {       ay.RenderMode = ay.RenderMode & (~mode); //去掉复合枚举的值，也可以使用^取异操作      }     }    }   }

public MainWindow()         {  InitializeComponent();  //DOCK数据绑定  foreach (Dock mode in Enum.GetValues(typeof(Dock)))  {      cboDockSelect.Items.Add(mode);      cboDockSelect.SelectedItem = rd.IconDockPlacement;  }         }

讲解一下Flags符合枚举的添加值和减去值的方法，aaronyang总结，xaml中使用英文逗号隔开表示多值

添加值：使用 | 或运算符，例子：枚举值1 | 枚举值2

有值就减去，无值就增加：用 ^ 运算符，例子：枚举值1 ^ 枚举值2

判断是否有值，如果有，就减去值，例子：枚举值1& (~枚举值2)

如果混搭的话，就有某些元素是否显示还是隐藏，我们拿到控件后使用FindName查找用户控件，然后设置其属性值

((TextBlock)aybtn.FindName("tbText")).Visibility = Visibility.Collapsed;

关于RenderMode变化，所以我们需要增加变化后的操作，用来控制排版和哪些显示还是隐藏

public AyImageButtonRenderMode RenderMode   {    get { return (AyImageButtonRenderMode)GetValue(RenderModeProperty); }    set { SetValue(RenderModeProperty, value); }   }   // Using a DependencyProperty as the backing store for RenderMode.  This enables animation, styling, binding, etc...   public static readonly DependencyProperty RenderModeProperty =    DependencyProperty.Register("RenderMode", typeof(AyImageButtonRenderMode), typeof(AyImageButton), new PropertyMetadata(AyImageButtonRenderMode.Icon | AyImageButtonRenderMode.Text, ButtonRenderChanged));   private static void ButtonRenderChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)   {    AyImageButton aybtn = (AyImageButton)d;    aybtn.IconDockChanged(aybtn, aybtn.IconDockPlacement);   }
