En el ejemplo de código siguiente se muestra cómo usar el BorderStyle enumeración y el BorderStyle, ShowLines, Scrollable, HideSelection y ShowRootLines propiedades.The following code example demonstrates how to use the BorderStyle enumeration and the BorderStyle, ShowLines, Scrollable, HideSelection and ShowRootLines properties. Para ejecutar este ejemplo, pegue el código siguiente en un formulario y llame a la InitializeTreeView método en el constructor del formulario o Load método.To run this example, paste the following code in a form and call the InitializeTreeView method in the form's constructor or Load method.
