The following code example adds a TreeView control to the first paragraph in the document, and then adds a parent node and two child nodes to the control. To use this example, run it from the ThisDocument class in a document-level project.

Private Sub WordRangeAddTreeView()
    Me.Paragraphs(1).Range.InsertParagraphBefore()
    Dim TreeView1 As Microsoft.Office.Tools.Word.Controls. _
        TreeView = Me.Controls.AddTreeView(Me.Paragraphs(1). _
        Range, 90.75F, 72.75F, "TreeView1")

    TreeView1.Nodes.Add("Customer Name")
    TreeView1.Nodes(0).Nodes.Add("First Name")
    TreeView1.Nodes(0).Nodes.Add("Last Name")
End Sub
private void WordRangeAddTreeView()
{
    this.Paragraphs[1].Range.InsertParagraphBefore();
    Microsoft.Office.Tools.Word.Controls.TreeView
         treeView1 = this.Controls.AddTreeView(
         this.Paragraphs[1].Range, 90.75F, 72.75F, "treeView1");

    treeView1.Nodes.Add("Customer Name");
