10126 : Why the treeview shows the plus (+) sign on nodes that do not have children?

Question

I am testing the VCL gantt components and am wondering why the treeview shows the plus (+) sign on nodes that do not have children?

Answer

As long as the Expanded property on the dataentities is set to false it will show the plus sign. Simply set Expanded=true on the nodes; if the childnode list have items the minus will show, otherwise the standard “nothing” will show.
