The Header property of the TreeViewItem contains the content that the TreeView displays for that item. This topic provides examples of these concepts. You can explicitly define the TreeView content or a data source can provide the content.

Private static DependencyObject GetDependencyObjectFromVisualTree(DependencyObject startObject, Type type) Viewed 262 times 0 I would like to construct a Hierarchical TreeView in WPF from an available XML data.This Data could be Dynamic so Tree may end up having many levels of children. (sender as TreeViewItem).ContextMenu = menu
For example, C class Level2NodeViewModel is used for data-binding level 2 node with: arrow-image + text + search-image + hyperlink. xaml files in the project solution: Each level node has a ViewModel for data binding. Each level node has its own HierarchicalDataTemplate. After adding a couple nodes at the root level, I have written code that loops through the tree structure like so: ItemCollection items treeView1. It is a 4-level TreeView with root node at level 0. Title="MainWindow" Height="350" Width="525"> I have a TreeView control that I have created in XAML in a WPF program. Sharing a simple example wherein we are generating dynamic menuitems for the context menu based on the node or treeviewitem selected in the treeview.
