System.Windows.Controls.TreeViewItem is a class in the C# programming language that allows developers to create and manipulate items for a tree view control. This class belongs to the System.Windows.Controls namespace.
Here are some code examples using TreeViewItem:
Example 1:
TreeViewItem item = new TreeViewItem(); item.Header = "Parent Node"; TreeViewItem childItem = new TreeViewItem(); childItem.Header = "Child Node"; item.Items.Add(childItem);
This code creates a new TreeViewItem object named "item". It sets the header text for the item to "Parent Node". Then it creates a new TreeViewItem object named "childItem", sets its header text to "Child Node", and adds it as a child item to the parent item.
This code creates a new TreeViewItem object with the header text "Parent Node". It then adds two child items to the parent item, each with their own header text.
These examples demonstrate how to use the TreeViewItem class to create and manipulate items in a tree view control. The package library for this class is the WPF (Windows Presentation Foundation) library, which provides a set of tools for creating graphical user interfaces in Windows applications.
