Do you have a question?

The "node" you just added has it's own "Nodes" property. What do you think is the next logical step?

If you would like to add a sub-node to the node, try this:

C#

string ItemName = "MTP/2 -3-PLY";
string subitemname = "op 1";

TreeNode node = new TreeNode(ItemName);
node.Nodes.Add(subitemname);
treeView1.Nodes.Add(node);

In case you want to add a childnode to the existing node, use this:

C#

var node = treeView1.Nodes[0]; //root node
node.Nodes.Add(subitemname);
