问题描述

在WPF中ControlTemplate和DataTemplate有什么区别?

What is difference between a ControlTemplate and a DataTemplate in WPF?

推荐答案

通常情况下，控件是为自身目的而呈现的，并且不会反映基础数据.例如，Button不会绑定到业务对象-纯粹是在那里，因此可以单击它.但是，通常会出现ContentControl或ListBox，以便它们可以为用户显示数据.

Typically a control is rendered for its own sake, and doesn't reflect underlying data. For example, a Button wouldn't be bound to a business object - it's there purely so it can be clicked on. A ContentControl or ListBox, however, generally appear so that they can present data for the user.

因此，DataTemplate用于为基础数据提供视觉结构，而ControlTemplate与基础数据无关，而只是为控件本身提供视觉布局.

A DataTemplate, therefore, is used to provide visual structure for underlying data, while a ControlTemplate has nothing to do with underlying data and simply provides visual layout for the control itself.

ControlTemplate通常只包含TemplateBinding表达式，绑定回控件本身的属性，而DataTemplate将包含标准的Binding表达式，绑定到其DataContext的属性(业务/域对象或视图模型).

A ControlTemplate will generally only contain TemplateBinding expressions, binding back to the properties on the control itself, while a DataTemplate will contain standard Binding expressions, binding to the properties of its DataContext (the business/domain object or view model).
