Occurs when the user double-clicks a TreeNode with the mouse.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
This event occurs when the user double-clicks any part of a tree node with the mouse, including the plus sign (+) or minus sign (-) that indicates whether the node is collapsed or expanded.
For more information about handling events, see Handling and Raising Events.
The following code example demonstrates how to handle the event and how to use the TreeNodeMouseClickEventArgs. To run this example, paste the code into a Windows Form that contains a TreeView named treeView1. Populate treeView1 with the names of files located in the c:\ directory of the system the sample is running on, and associate the event of treeView1 with the treeView1_NodeMouseDoubleClick method in this example. This example requires that the user has administrator privileges on the machine running the example.
