Working with Nodes Add/Remove operations The nodes displayed in the TreeListView control are stored in Nodes property. This is an object from TreeListViewNodeCollection class, which has several methods and events you can use to add, remove, clear or make any other operation that will change the collection. Here is a list of methods that you can use: • Add – adds a new node at the end of the collection • AddRange – add a set of nodes to the end of the collection • Clear – empties the list • Remove – deletes the node from the collection • RemoveAt – deletes the node that is located at specified location in the collection Here is an example how to add a new node programmatically to the collection: [VB] Dim node As New TreeListViewNode(“New node”) Me.treeListView1.Node.Add(node) [C#] TreeListViewNode node = new TreeListViewNode("New node"); this.treeListView1.Nodes.Add(node); To insert this node at a specified position in the collection, use the Insert method: [VB] ' Adds the node at sixth position in the collection Me.treeListView1.Nodes.Insert(5, node) [C#] // Adds the node at sixth position in the collection this.treeListView1.Nodes.Insert(5, node); When you add a new node to the TreeListView control, this process is accompanied with two events: • NodeAdding – it is fired before node is added and can be cancel the add operation • NodeAdded – it is fired after the node is added To remove a node from the collection, two methods can be used: [VB] ' Removes the node from the collection Me.treeListView1.Nodes.Remove(node) ' Removes the node located at the specified location from the collection Me.treeListView1.Nodes.RemoveAt(5) [C#] // Removes the node from the collection this.treeListView1.Nodes.Remove(node); // Removes the node located at the specified location from the collection this.treeListView1.Nodes.RemoveAt(5); If you wan to remove all nodes, use the Clear method 39
