Color de primer plano del nodo de árbol.

Ejemplos

En el ejemplo de código siguiente se crea un nodo de árbol raíz para asignar nodos de árbol secundarios. Se agrega un nodo de árbol secundario para cada Customer objeto de un ArrayList objeto al nodo de árbol raíz, así como un nodo de árbol secundario para cada Order objeto asignado al Customer objeto . El Customer objeto se asigna a la Tag propiedad y los nodos de árbol que representan Customer objetos se muestran con Orange texto. En este ejemplo se requiere que tenga un Customer objeto y Order definido, un TreeView control en y Formun ArrayList elemento denominado customerArray que contenga Customer objetos .

ref class Customer
{
public:
   ArrayList^ CustomerOrders;
   String^ CustomerName;
   Customer( String^ myName )
   {
      CustomerName = myName;
      CustomerOrders = gcnew ArrayList;
   }

};

ref class Order
{
public:
   String^ OrderID;
   Order( String^ myOrderID )
   {
      this->OrderID = myOrderID;
   }

};
