![]() However, as soon as things get a bit more complicated, the advantages of using data bindings gets more obvious. This first example was very simple, in fact so simple that we might as well have just added the TreeView items manually, instead of generating a set of objects and then binding to them. I instruct it to use the I tems property for finding child items, by setting the ItemsSource property of the template, and inside of it I define the actual template, which for now just consists of a TextBlock bound to the Title property. In the XAML markup, I have specified a HierarchicalDataTemplate for the ItemTemplate of the TreeView. Public partial class TreeViewDataBindingSample : Window Namespace WpfTutorialSamples.TreeView_control In the following example, will show you just how easy it is to get started with the HierarchicalDataTemplate: Instead, we use the HierarchicalDataTemplate, which allows us to template both the tree node itself, while controlling which property to use as a source for child items of the node. The WPF TreeView supports data binding, like pretty much all other WPF controls does, but because the TreeView is hierarchical in nature, a normal DataTemplate often won’t suffice.
