hierarchicaldatatemplate

In my TreeView I use two differnt classes for binding. For example, I have a Group what can have ChildGroup and can have Items. Example code of this classes: using System.Collections.Generic; using System.Collections.ObjectModel; namespace WpfApplication1 { public class Group { public Group(string name) { Name = name; items = new ObservableCollection<Item>(); groups = new ObservableCollection<Group>(); } public string Name { get; set; } private ObservableCollection<Item> items; private ObservableCollection<Group> groups; public ObservableCollection<Item> Items { get { return items; } } public

I'm not sure how to approach this: I want a TreeView that will display some simple data from a hierarchical data structure. As a basic example (In XML, cause it's easy to type): <Node text="Root"> <Node text="Item 1"> <Node text="Item 1.1" /> </Node> <Node text="Item 2"/> </Node> The catch is that this could theoretically nest infinitely deep, so you can't statically define x number of levels and be done with it. Is there a way to define a HierarchicalDataTemplate that can account for this kind of structure? HeirarchicalDataTemplate is used exactly to solve this kind of issue. You can just use

just starting with wpf. I need to bind the object (Hierarchical) Folder public class Folder { public Folder() { this.Name = string.Empty; this.Modules = new ObservableCollection<Module>(); this.Folders = new List<Folder>(); this.HasChild = false; } public Folder(Folder parent) { this.Name = string.Empty; this.Modules = new ObservableCollection<Module>(); this.Folders = new List<Folder>(); this.HasChild = false; this.Parent = parent; } public bool HasChild { get; set; } public string Name { get; set; } public List<Folder> Folders { get; set; } public ObservableCollection<Module> Modules { get;

I have a wpf tree view that displays nodes of various types with corresponding images such as folder images. Initially, the tree and its nodes with corresponding images display as expected. However when a node is expanded, the expectation is that the image for the expanded node should swap to an expanded image. I'm trying to use HierarchicalDataTemplate triggers to set this up. Should the triggers be set up differently? The tree looks something like: (Folder Image) Solutions (SolutionsViewModel) --(Solution Image) Solution 1 (Solution) --(Solution Image) Solution 2 (Solution) (Folder Image)

I have Menu in my app. I'm visualizing it using hierarchical data template: <MenuItem Header="Main menu" ItemsSource="{Binding ApplicationMenu}" > <MenuItem.ItemTemplate> <HierarchicalDataTemplate DataType="{x:Type tm:RMenuItem}" ItemsSource="{Binding Path=ChildrenItems}"> <MenuItem Header="{Binding Name}" Command="{Binding RunOperationCommand}" /> </HierarchicalDataTemplate> </MenuItem.ItemTemplate> </MenuItem> menu looks like as it should, but Command for each menu item is not fired! Even more - it is not bounded, which could be seen in debugger: get accessor of ICommand Property has been

I have a collection of Database objects, each containing collections of Schema objects and User objects. I want to bind them to a TreeView, but adding additional static levels in the hierarchy, so that the resulting TreeView looks more or less like this: <TreeView> <TreeViewItem Header="All the databases:"> <TreeViewItem Header="Db1"> <TreeViewItem Header="Here's all the schemas:"> <TreeViewItem Header="Schema1"/> <TreeViewItem Header="Schema2"/> </TreeViewItem> <TreeViewItem Header="Here's all the users:"> <TreeViewItem Header="User1"/> <TreeViewItem Header="User2"/> </TreeViewItem> <
