![]() | DataTemplateKey | Gets the default key of the DataTemplate. (Inherited from DataTemplate.) |
![]() | DataType | Gets or sets the type for which this DataTemplate is intended. (Inherited from DataTemplate.) |
![]() | Dispatcher | Gets the Dispatcher this DispatcherObject is associated with. (Inherited from DispatcherObject.) |
![]() | HasContent | Gets a value that indicates whether this template has optimized content. (Inherited from FrameworkTemplate.) |

![]() | ItemStringFormat | Gets or sets a composite string that specifies how to format the items in the next level in the data hierarchy if they are displayed as strings. |
![]() | ItemTemplate | Gets or sets the DataTemplate to apply to the ItemTemplate property on a generated HeaderedItemsControl (such as a MenuItem or a TreeViewItem), to indicate how to display items from the next level in the data hierarchy. |
![]() | ItemTemplateSelector | Gets or sets the DataTemplateSelector to apply to the ItemTemplateSelector property on a generated HeaderedItemsControl (such as a MenuItem or a TreeViewItem), to indicate how to select a template to display items from the next level in the data hierarchy. |
![]() | Resources | Gets or sets the collection of resources that can be used within the scope of this template. (Inherited from FrameworkTemplate.) |

In the following example, ListLeagueList is a list of League objects. Each League object has a Name and a collection of Division objects. Each Division has a Name and a collection of Team objects, and each Team object has a Name.
