Question

I am trying to figure out how to highlight a node on a treeview at runtime, I know the node index but cannot see how I can select it in Code. Also how can I collapse any other open node’s and expand the selected one in code

thanks

Answer 1

1) Collapse the Treeview using the the FullCollapse method

TreeView1.FullCollapse;

2) To Select (highlight) a Node assign the Selected property

TreeView1.Selected:=TreeView1.Items[NodeIndex];

3) Expand the selected Node using the Expand method

TreeView1.Items[NodeIndex].Expand(True);
