Public partial class TreeViewDataBindingSample : Window Namespace WpfTutorialSamples.TreeView_control In the following example, I'll show you just how easy it is to get started with the HierarchicalDataTemplate: Which property to use as a source for child items of the node. Instead, we use the HierarchicalDataTemplate, which allows us to template both the tree node itself, while controlling The WPF TreeView supports data binding, like pretty much all other WPF controls does, but because the TreeView is hierarchical in nature, a normalĭataTemplate often won't suffice. Step 5: Create XAML Page to Display treeview CompanyDetailView.The TreeView control: TreeView, data binding and multiple templates I created two methods for getting a list of Departments and List of Employees and bind to each viewmodel properties. This viewmodel is for CompanyDetailView.xaml page declared ObservableCollection DepartmentCollection property to hold collection of departments to bind in treeviewitems. Public class EmployeeViewModel : ViewModelBase Step 3: Create viewmodels for Each Model EmployeeViewModel.cs If we want to notify viewmodels property change, then we must inherit this class in every viewmodel, and override RaisePropert圜hanged method to notify property change. Temp( this, new Propert圜hangedEventArgs(propertyName))

Propert圜hangedEventHandler temp = Propert圜hanged

/ /// protected void RaisePropert圜hanged( String propertyName) / /// Raise when property value propertychanged RaisePropert圜hanged(GetPropertyName(propertyExpression)) / /// /// protected virtual void RaisePropert圜hanged / /// Raise when property value propertychanged or override propertychage / /// /// /// public static string GetPropertyName(Expression> e) Public event Propert圜hangedEventHandler Propert圜hanged Public abstract class ViewModelBase:INotifyPropert圜hanged Step 1: Create Models for Department and Employee We wish to bind departments in parent node and employees for each department in child nodes in Treeview. This example is for a Company that has many departments and each department has employees.

You can change the style of treeview using custom template style. WPF has HierarchicalDataTemplate to bind treeviewitem in hierarchical data by setting ItemsSource property. One parent node has multiple child nodes.

Treeview is used to display data in a hierarchical series with parent child relationship. All business logic related to view is written in viewmodel. It has properties, commands and propertychanged notification logic to execute when any property raise or changed. Viewmodel is the mediator between view and viewmodel. View is used for Data binding and displaying data. It contains visual controls and rich UI using styles and templates and storyboard. Model/View/ViewModel also relies on one more thing: a general mechanism for data binding.
