该控件叫Summary, 主要是一些汇总信息的显示，有几个地方用，之前都是分散到各个XAML 文件里，不统一。
本人WPF新手，对XAML了解不多，做这个软件基本上都是用CM，界面布局用AvalonDock。
由于缺乏相关经验，又没有一个能问得上的人指导，写这个控件费了我很长时间（啥时有空啥时动动）。
之前主要做一些功能方面的，没有心思美化界面，现在虽然还有很多功能没写，但是基本上够自己用了，放下心思来做一些界面上的东西，要不然何苦选择WPF？先看一下图：该CustomControl 由4部分组成：大标题，小标题，值及Detail。
虽然细分这么多，但实质上还是一个列表类的控件，所以选择继承自ItemsControl.做这个控件的时候，遇到了一些详细的问题不知道怎么解决，Google/Bing 都没有找到我要了解的，Baidu 更不用提了，漫天的转载，Copy.1, 类似ComboBox 的DisplayMemberPath 如何弄？既然都自定控件了，当然是想让它适用不同场景，不能局限于某一个实体类，最好是能像DisplayMemberPath ValueMemberPath 这样的属性。
这里，我定义了：ItemTitlePathProperty 及ItemValuePathProperty 来处理。
2，有了上面两个依赖属性，但是还不足以处理更多的场景，最好是能有不同的Template 。
这里我定义了：TitleTemplate / ValueTemplate及DetailTemplate.第一个问题，只需定义一个简单的DataTemplate ，然后用TemplateBinding 即可做到。
但是要和第二个问题结合在一起，就牵扯到模板切换及数据切换的问题，因为第一问题所用的数据被指定为某实体类的某个属性，第二个问题的数据要指定为整个实体。
解决第一个问题，需要重写PrepareContainerForItemOverride 方法，第二个需要重写OnApplyTemplate不多说了，怕误导大家，毕竟，我懂的不多，上代码，供参考：模板文件：1<ResourceDictionaryxmlns="/winfx/2006/xaml/presentation"2xmlns:x="/winfx/2006/xaml"3xmlns:local="clr-namespace:AsNum.WPF.Controls"4>567<DataTemplate x:Key="SummaryTitleTemplate">8<TextBlock Text="{Binding}" Foreground="White"/>9</DataTemplate>1011<DataTemplate x:Key="SummaryValueTemplate">12<Border HorizontalAlignment="Right" Background="#FF535C7B" CornerRadius="10">13<TextBlock Text="{Binding}" Padding="8,3"Foreground="White"/>14</Border>15</DataTemplate>161718<Style TargetType="{x:Type local:Summary}">19<Setter Property="Template">20<Setter.Value>21<ControlTemplate TargetType="{x:Type local:Summary}"> 22<Border Background="{TemplateBinding Background}"23BorderBrush="{TemplateBinding BorderBrush}"24BorderThickness="{TemplateBinding BorderThickness}"25>2627<StackPanel Height="auto">28<Border Padding="20,5"CornerRadius="5,5,0,0" Background="#10a8ab">29<TextBlock Text="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Typelocal:Summary}}, Path=Title}" FontSize="18.667" Foreground="White" HorizontalAlignment="Center"/>30</Border> 31<Border Background="#FF394165" CornerRadius="0,0,3,3" Padding="5">32<ItemsPresenter />33</Border>34</StackPanel>3536</Border>37</ControlTemplate>38</Setter.Value>39</Setter>40</Style>4142<Style TargetType="{x:Type local:SummaryItem}">43<Setter Property="Template">44<Setter.Value>45<ControlTemplate TargetType="{x:Typelocal:SummaryItem}">46<Border x:Name="Item"47Padding="3"48BorderBrush="{TemplateBinding BorderBrush}"49BorderThickness="{TemplateBinding BorderThickness}">505152<Border.Background>53<SolidColorBrush />54</Border.Background>5556<StackPanel>57<DockPanel>58<ContentControl x:Name="PART_Title" 59Content="{TemplateBinding Title}"60ContentTemplate="{StaticResource SummaryTitleTemplate}"61/>6263<ContentControlx:Name="PART_Value"64Content="{TemplateBinding Value}"65ContentTemplate="{StaticResource SummaryValueTemplate}"66Width="auto"67DockPanel.Dock="Right"68HorizontalAlignment="Right"69/>7071</DockPanel>72<ContentControl Margin="0,2,0,2"x:Name="PART_Detail" ContentTemplate="{TemplateBinding DetailTemplate}"/> 73</StackPanel>7475<Border.Triggers>76<EventTriggerRoutedEvent="Border.MouseEnter">77<BeginStoryboard>78<Storyboard>79<ColorAnimationTo="#FF535C7B" Duration="0:0:1"80Storyboard.TargetName="Item"81Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)"/>82</Storyboard>83</BeginStoryboard>84</EventTrigger>85<EventTriggerRoutedEvent="Border.MouseLeave">86<BeginStoryboard>87<Storyboard>88<ColorAnimationTo="Transparent" Duration="0:0:1"89Storyboard.TargetName="Item"90Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)"/> 91</Storyboard>92</BeginStoryboard>93</EventTrigger>94</Border.Triggers>959697</Border>98</ControlTemplate>99</Setter.Value>100</Setter>101</Style>102103</ResourceDictionary>Summary.cs1using System;2using System.Collections.Generic;3using System.Collections.ObjectModel;4using System.Linq;5using System.Text;6using System.Threading.Tasks;7using System.Windows;8using System.Windows.Controls;9using System.Windows.Data;10using System.Windows.Documents;11using System.Windows.Input;12using System.Windows.Media;13using System.Windows.Media.Imaging;14using System.Windows.Navigation;15using System.Windows.Shapes;1617namespace AsNum.WPF.Controls {18public class Summary : ItemsControl {192021public static DependencyProperty TitleProperty = DependencyProperty.Register("Title", typeof(string), typeof(Summary));2223public static DependencyProperty ItemTitlePathProperty = DependencyProperty.Register("ItemTitlePath", typeof(string), typeof(Summary));
