Display a wait cursor while the TreeNodes are being created. IEnumerator^ myEnum = customerArray->GetEnumerator() Ĭustomer^ customer1 = safe_cast(myEnum->Current) įor ( int y = 0 y CustomerOrders->Add( gcnew Order( "Order " + y ) ) Add orders to each Customer object in the ArrayList. Add customers to the ArrayList of Customer objects.įor ( int x = 0 x Add( gcnew Customer( "Customer " + x ) ) Ref class Customer: public System::Object It also requires that you have a cursor file that is named MyWait.cur in the application directory and that you have created an instance of a TreeView control on a Form. This example requires that you have a Customer object that can hold a collection of Order objects. The repainting of the TreeView is suppressed by using the BeginUpdate and EndUpdate methods, and a wait Cursor is displayed while the TreeView creates and paints the TreeNode objects. In this example, 1,000 customers are displayed with 15 orders each. The root tree nodes display customer names, and the child tree nodes display the order numbers assigned to each customer.
