Using TreeView in runtime vs IDE

There is something strange about TreeView in .NET Framework 1.1. You can't use TreeView object to run this syntax: treeView1->SelectedNode->Nodes->Add(S"Example1");
on the TreeView object that you create inside the program (on the fly), but you can use the syntax when you create the object from IDE (you drag the object from Component Toolboc on visual studio .NET IDE)
