![]() ![]() This example displays the Region's RegionName property in a TextBlock. In the following picture you can see that here. template that the TreeView should use to display the data at this node. You manage ItemContainerGenerator status for each item (some code provided as examples). Menu hierarchical binding is nearly similar to a TreeView Binding. You have 3 choices: You disable the virtualization of items: , but this could have impact on performance.![]() I have a tree-like class that can have two different types of children. xmlns:d=""Ä:DesignHeight="300" d:DesignWidth="300"> can see the hierarchical TreeView in the preceding picture. Something like this :It would be perfect if I could add a custom (CLASSES, STUDENTS, etc.) naming somehow to each HierarchicalDataTemplate. You need to specify two HierarchicalDataTemplates, one for objects of type a, and the other for objects of type b. I would like to do this without altering the objects bound to the TreeView. We have one TexBlock control inside HierchicalDataTemplate, that will show the title of each element in a hierarchical manner. This is where WPFs ability to apply templates to normal.

You can see the TreeView in the following XAML code: example, the TreeView doesn't explicitly set its ItemTemplate. Here XmlDataProvider is the time source to the TreeView. TreeView.ItemTemplate is set using a HierarchicalDataTemplate object instead.It has an ItemsSource property that selects the children for the item the template represents. HierachicalDataTemplate works just like a normal data template, but with one additional feature. Hierarchical binding is able to display a sequence of items and each item may have child items. As far as I can tell, I cant access the binding from the ResourceDictionary xaml. ![]() I need to be able to programatically change the template for each TreeViewItem based on its bindings value. Note that it is the TreeViewItem and MenuItem which handle the hierarchy of parent to child collection. I have a TreeView with a custom resource dictionary for its TreeViewItems template. It not only enables you to change the presentation of such data, but enables you to directly bind a hierarchy of objects to an element that can deal with hierarchies, such as the items of a TreeView or Menu control.
