Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type ControlCollection. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
Exceptions
| Exception | Condition |
|---|---|
| ArgumentNullException | The name argument is nulla null reference (Nothing in Visual Basic) or has zero length. |
| ControlNameAlreadyExistsException | A control with the same name is already in the ControlCollection instance. |

The AddTreeView method enables you to add TreeView objects to the end of the ControlCollection. To remove a TreeView control that was previously added programmatically, use the Remove method.
Examples
The following code example adds a TreeView control to the top of the worksheet, and then adds a parent node and two child nodes to the control. To use this example, run it from the Sheet1 class in a document-level project.
Private Sub ExcelAddTreeView()
Dim TreeView1 As Microsoft.Office.Tools.Excel. _
Controls.TreeView = Me.Controls.AddTreeView( _
0, 0, 90.75, 72.75, "TreeView1")
TreeView1.Nodes.Add("Customer Name")
TreeView1.Nodes(0).Nodes.Add("First Name")
TreeView1.Nodes(0).Nodes.Add("Last Name")
End Sub 'ExcelAddTreeView
private void ExcelAddTreeView()
{
Microsoft.Office.Tools.Excel.Controls.TreeView
treeView1 = this.Controls.AddTreeView(
0, 0, 90.75, 72.75, "treeView1");
treeView1.Nodes.Add("Customer Name");
treeView1.Nodes[0].Nodes.Add("First Name");
treeView1.Nodes[0].Nodes.Add("Last Name");
