how to add a node in a specific node

[saadmechiche]

Hi

I am using a form with 2 buttons and one treeview
in the first button , I can add a node with this code

dim c as treeNode
c=TreeView1.Nodes.Add("hello")

in the second button i can add a node but only in the last node
c.nodes.add("World")

My question is how to add a node in the third node or a specific node of the treeView

Thank you

Instead of just specifying the text of the node when you add it to the tree, give each node a unique key. That way you can use the Key to reference the specific node.

TreeView1.Nodes.Add("hello", "Hello World") 'the first value is the key
TreeView1.Nodes("hello").Add("newNode", "Child node")

Ok , how can i know the the name of a specific node
for example the 3rd node
Thank you

oh actually the code is not working :-(

Oh sorry, I wrote the code directly in the post. This is what it should look like.

TreeView1.Nodes.Add("hello", "Hello World") 'the first value is the key
TreeView1.Nodes("hello").Nodes.Add("newNode", "Child node")

Or if you think it's easier to read:

TreeView1.Nodes.Add("hello", "Hello World") 'the first value is the key
Dim node As TreeNode = TreeView1.Nodes("hello")
node.Nodes.Add("newNode", "Child node")

You can also reference the nodes by index

Dim node As TreeNode = TreeView1.Nodes(0) 'the first node
