TreeNode.FullPath

[zaboboa]

Hello, If I have a full path to the selected node, is there a way to expand the treeview after I refresh it, to that particular node using the path? Thank you!

string nodeToFind = "node11"; // node's you want to show name TreeNode[] nodes = treeView1.Nodes.Find(nodeToFind, true); if(nodes != null && nodes.Length > 0){ TreeNode node = nodes[0]; while(node != treeView1.TopNode){ node.Parent.Expand(); node = node.Parent; } }

life is study!!!

Thank you very much. The only problem, if you don't set the name of the node, you are out of luck. :-(

Whenever you add a node, get its full path and store it into node's name. TreeNode tn = this.treeView1.Nodes.Add("AAA"); tn.Name = tn.FullPath; When you want to expand the node having, let's say, "The_wanted_path" you use this:

TreeNode [] tn = this.treeView1.Nodes.Find("The_wanted_path", true);
if ( tn[0] != null )
{
TreeNode Parent = tn[0].Parent;
TreeNode FirstParent = Parent;
while (Parent != null)
{
Parent = Parent.Parent;
if (Parent != null) FirstParent = Parent;
}
tn[0].Expand();
if (FirstParent != null) FirstParent.Expand();
}
