DataTemplate ControlTemplate

1. we can search many posts about this topic. some valuable link: DataTemplate和ControlTemplate的关系,

2. we can see some definition about ControlTemplate, DataTemplate, HierarchicalDataTemplate

   2.1. A ControlTemplate is used to define/change the way a class derived from Control looks, such as Buttons, ListBox, ScrollBar. However, some "Controls" you use are not derived from Control: Best example is the TextBlock class. The TextBlock cannot have a ControlTemplate.

   ControlTemplate is connected to the Template property of the Control, we can set it directly to the property.

   2.2 DataTemplate is closelly linked with the “Content” in WPF. Certain controls are made to display "Content". Content can be anything, such as Image, Text, Object.... in fact, it is defined as an "object" type. The DataTemplate simply defines how a particular content (or content type) is meant to be displayed.

   DataTemplate is used to display Content of a Control, the Relative property is CellTemplate,ContentTemplate,ItemTemplate.

   2.3. HierarchicalDataTemplate is an extension of DataTemplate with an additional ItemSource property. It is used to render hierarchical data in controls like treeview or menu.
   Example: Usually, a string is displayed using a simple TextBlock... However, if you want a custom text layout, decoration, alignement, ... you would need to define an Alternate DataTemplate.
