Ejemplos

En el ejemplo de código siguiente se selecciona el apropiado TreeNode después de determinar si el TreeNode pasa en está seleccionada y que TreeNode para seleccionar.The following code example selects the appropriate TreeNode after determining if the TreeNode passed in is selected and which TreeNode to select. En este ejemplo requiere que haya un Form con un TreeView control que tiene un TreeNodeCollection que contenga varias TreeNode objetos.This example requires that you have a Form with a TreeView control that has a TreeNodeCollection containing several TreeNode objects. También requiere que haya un ComboBox con los siguientes elementos: "Anterior", "PreviousVisible", "Siguiente", "NextVisible", "First" y "Last".It also requires that you have a ComboBox with the following items: "Previous", "PreviousVisible", "Next", "NextVisible", "First", and "Last".
