I have a treeview where i want to create the nodes by getting data from a database,
but i don't want to create all the nodes, i want to create the nodes of the first level, and when i click a node its children will be added to the tree by code, so i did all this but the problem is, i want to display a "plus" beside the node that i know that will have children even if it doesn't have for now, so is this possible ?
