To add static C1TreeView items to the C1TreeView control in the code behind file, edit the code in your application so it appears like the following:

Visual Basic	Copy Code
Imports C1.Xaml Class MainPage Public Sub New() InitializeComponent() InitializeTreeView() End Sub Private Sub InitializeTreeView() ' Remove items that were added at design time Tree.Items.Clear() Dim booklist As New C1TreeViewItem() booklist.Header = "Book List" Tree.Items.Add(booklist) ' Adding child items Dim language As New C1TreeViewItem() language.Header = "Language Books" booklist.Items.Add(language) ' Adding child items Dim security As New C1TreeViewItem() security.Header = "Security Books" booklist.Items.Add(security) ' Adding child items Dim classic As New C1TreeViewItem() classic.Header = "Classic Books" booklist.Items.Add(classic) ' Adding child items Dim subclassic As New C1TreeViewItem() subclassic.Header = "Catch-22" classic.Items.Add(subclassic) Dim subclassic2 As New C1TreeViewItem() subclassic2.Header = "The Great Gatsby" classic.Items.Add(subclassic2) End Sub End Class

        Tree.Items.Clear()
        Dim booklist As New C1TreeViewItem()
        booklist.Header = "Book List"
        Tree.Items.Add(booklist)

        ' Adding child items
        Dim language As New C1TreeViewItem()
        language.Header = "Language Books"
        booklist.Items.Add(language)
