TreeView1.Background = new SolidColorBrush(Color.FromRgb(255, 255, 255)) Step 7) Button Inside StatckPanel, Which will Add items to TreeView. This topic introduces the TreeView and TreeViewItem controls, and provides simple examples of their use. TreeView1.Background = new SolidColorBrush(Color.FromRgb(100, 100, 100)).Now focus should goto StatckPanel rather than treeview control, so set background color for.Hier finden Sie Informationen zu den Stilen und Vorlagen für das TreeView-Steuerelement, mit denen Sie die standardmäÃige Steuerelementvorlage (ControlTemplate) ändern können, um dem Steuerelement ein einzigartiges Aussehen zu verleihen.

We define a TreeView & bind the ItemSource to our ItemsA. In the real world these lists are replaced with your queried data from the Database, Json, Xml etc:įinally our Xaml designer view. The ViewModel instantiates a collection of ItemA class objects, ItemA defines a collection of ItemBâs in the constructor & ItemB defines a list of ItemC. To acheive this we need to put our OOP hat on & build a hierarchy of classes to provide the TreeView with our data at run time. If you donât know what to expect at run time then we canât hard code the values, we need a dynamic TreeView! This is fine unless you have dynamic data. You could also bind these values to string property values exposed in your viewModel. TreeViewItems are nested within the TreeView & Headers are hardcoded. ![]() Hard coding your values is simple enough however I quickly learned that building a dynamic hierarchical TreeView was to be a little more complex!įirstly, hereâs some simple hard coded Xaml: I got about using WPFâs TreeView control. ![]() I recently had a UI design which required the use of a tree view. ![]()
