模板使用方式:首先定义模板,然后在把对应的key应用到控件对应的属性中;
属性对应:
控件模板,对应控件的Template;
数据模板,对应控件的ItemTemplate属性;
面板模板,对应控件的ItemsPanel属性。
控件模板:如果控件的样式不能满足,可自定义控件模板来设计样式。
数据模板:内容控件通过ContentTemplate属性支持数据模板;列表控件(即继承自ItemsControl类的控件),通过ItemTemplate属性支持数据模板,该模板用于显示由ItemSource提供集合中的每一项。
面板模板:ItemsPanelTemplate用于指定项的布局。 ItemsControl 类型具有一个类型为ItemsPanelTemplate 的 ItemsPanel 属性。
一、控件模板:如果控件的样式不能满足,可自定义控件模板来设计样式。

说明:控件模板和数据模板的关系
控件只是数据和行为的载体,至于它本身长什么样子和数据长什么样子都是靠Template决定的。决定控件外观的是ControlTemplate,决定数据外观的是DataTemplate,它们正是Control类的Template和ContentTemplate两个属性的值。
一般来说,ControlTemplate内都有一个ContentPresenter,这个ContentPresenter的ContentTemplate就是DataTemplate类型。所以数据模板和控件模板的关系如下图所示:
Control类型
- Template属性 (ControlTemplate类型)
- ContentPresenter
- ContentTemplate (DataTemplate类型)
ContentControl类型
- Template属性 (ControlTemplate类型) 继承自Control
- ContentTemplate (DataTemplate类型)
ItemsControl类型
- Template属性 (ControlTemplate类型) 继承自Control
- ItemsPanel属性 (ItemsPanelTemplate类型) 指定布局容器
- ItemTemplate属性 (DateTemplate类型) 每个Item的Template
3.面板模板
增加ItemsPanelTemplate调整面板布局
