public virtual System.Windows.Forms.TreeNode Add (string? text);

abstract member Add : string -> System.Windows.Forms.TreeNode
override this.Add : string -> System.Windows.Forms.TreeNode

Public Overridable Function Add (text As String) As TreeNode

Parameters

text: String

The label text displayed by the TreeNode.

Returns

TreeNode

A TreeNode that represents the tree node being added to the collection.

Examples

The following code example displays customer information in a TreeView control. The root tree nodes display customer names, and the child tree nodes display the order numbers assigned to each customer. In this example, 1,000 customers are displayed with 15 orders each. The repainting of the TreeView is suppressed by using the BeginUpdate and EndUpdate methods, and a wait Cursor is displayed while the TreeView creates and paints the TreeNode objects. This example requires that you have a Customer object that can hold a collection of Order objects. It also requires that you have created an instance of a TreeView control on a Form.

Remarks

This version of the Add method allows you to add previously created TreeNode objects to the end of the tree node collection.

You can also add new TreeNode objects to the collection by using the AddRange or Insert methods.

To remove a TreeNode that you previously added, use the Remove, RemoveAt, or Clear methods.

Note

A TreeNode can be assigned to only one TreeView control at a time. To add the tree node to a new tree view control, you must remove it from the other tree view first or clone it.
