Treeview will highlight node @runtime

Question

I am trying to figure out how to select a node in a tree structure at runtime, I know the node index, but I don’t see how I can select it in the code. Also how can I collapse any other open node and expand the selected one in the code

thanks

Answer 1

1) Collapse TreeView using 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);
