Asp . net provides templated controls that expose a number of template properties that define the control s content and layout Asp . net提供了模板化控件，这种控件公开若干模板属性，开发人员可以应用这些属性来标记语言目标。
However , a single templated control might refer to multiple sets of templates , with each template set having different device - specific criteria 但是，单个模板化控件可能引用多个模板集，而每个模板集都具有不同的特定于设备的条件。
When working with templated controls , you might not know until run time what templates you need or what text or controls the template should contain 控件这样的模板化控件时，直到运行时，您可能才会知道需要什么模板或模板中应包含哪些文本或控件。
When the asp . net page parser encounters a templated control , it parses the control s template and dynamically creates child controls that supply the visual interface 当asp . net页分析器遇到模板化控件时，它分析控件的模板，并动态地创建能提供可视化界面的子控件。
Thus , you can have multiple - templated controls that reference the same style , use the same template sets , and provide the same benefits of encapsulation that a style provides 因此可以有多个模板化控件，它们引用同一样式，使用相同的模板集，而且提供与样式所提供的封装相同的优点。
Control whose text property has been data bound displays the word " databound " on the label . without the data - binding handler , the label would be invisible at design - time , as it does not have a designer to bind its data - bound properties while in a templated control at design - time 如果没有数据绑定处理程序，则此标签在设计时将是不可见的，这是因为当在设计时处于模板化控件中时，它没有对其数据绑定属性进行绑定的设计器。
