DataTemplateSelector的用法

Typically, you create a DataTemplateSelector when you have more than one DataTemplate for the same type of objects and you want to supply your own logic to choose a DataTemplate to apply based on the properties of each data object. Note that if you have objects of different types you can set the DataType property on the DataTemplate. If you do that then there is no need to create a DataTemplateSelector. Furthermore, if you have objects of the same type but with different properties, you can also consider using a DataTrigger or a data converter.

To create a template selector, create a class that inherits from DataTemplateSelector and override the SelectTemplate method. Once your class is defined you can assign an instance of the class to the template selector property of your element.
