Ejemplos

En el ejemplo de código siguiente se muestra cómo NodeMouseDoubleClick controlar el evento y cómo TreeNodeMouseClickEventArgsusar.The following code example demonstrates how to handle the NodeMouseDoubleClick event and how to use the TreeNodeMouseClickEventArgs. Para ejecutar este ejemplo, pegue el código en un formulario de Windows Forms TreeView que treeView1contenga un denominado.To run this example, paste the code into a Windows Form that contains a TreeView named treeView1. Rellene treeView1 los nombres de los archivos ubicados en c:\ el directorio del sistema en el que se está ejecutando el ejemplo y NodeMouseDoubleClick asocie el treeView1 evento de treeView1_NodeMouseDoubleClick con el método en este ejemplo.Populate treeView1 with the names of files located in the c:\ directory of the system the sample is running on, and associate the NodeMouseDoubleClick event of treeView1 with the treeView1_NodeMouseDoubleClick method in this example.
