Beispiel

Im folgenden Codebeispiel wird die Verwendung der BorderStyle-Enumeration und der TreeView.BorderStyle-Eigenschaft, der TreeView.HideSelection-Eigenschaft und der TreeView.ShowRootLines-Eigenschaft veranschaulicht. Zum Ausführen des Beispiels fügen Sie folgenden Code in ein Formular ein, und rufen Sie die InitializeTreeView-Methode im Konstruktor oder in der Load-Methode des Formulars auf.

' Declare the TreeView control.
Friend WithEvents TreeView1 As System.Windows.Forms.TreeView

' Initialize the TreeView to blend with the form, giving it the 
' same color as the form and no border.
Private Sub InitializeTreeView()

    ' Create a new TreeView control and set the location and size.
    Me.TreeView1 = New System.Windows.Forms.TreeView
    Me.TreeView1.Location = New System.Drawing.Point(72, 48)
    Me.TreeView1.Size = New System.Drawing.Size(200, 200)

    ' Set the BorderStyle property to none, the BackColor property to  
    ' the form's backcolor, and the Scrollable property to false.  
    ' This allows the TreeView to blend in form.
    Me.TreeView1.BorderStyle = BorderStyle.None
    Me.TreeView1.BackColor = Me.BackColor
    Me.TreeView1.Scrollable = False

    
    ' Set the ShowRootLines and ShowLines properties to false to 
    ' give the TreeView a list-like appearance.
    Me.TreeView1.ShowRootLines = False
    Me.TreeView1.ShowLines = False

    ' Add the nodes.
