How to: Attach a ShortCut Menu to a TreeView Node
The Windows Forms xref:System.Windows.Forms.TreeView control displays a hierarchy of nodes, similar to the files and folders displayed in the left pane of Windows Explorer. By setting the xref:System.Windows.Forms.Control.ContextMenuStrip%2A property, you can provide context-sensitive operations to the user when they right-click the xref:System.Windows.Forms.TreeView control. By associating a xref:System.Windows.Forms.ContextMenuStrip component with individual xref:System.Windows.Forms.TreeNode items, you can add a customized level of shortcut menu functionality to your xref:System.Windows.Forms.TreeView controls.
To associate a shortcut menu with a TreeNode programmatically
-
Instantiate a xref:System.Windows.Forms.TreeView control with the appropriate property settings, create a root xref:System.Windows.Forms.TreeNode, and then add subnodes.
-
Instantiate a xref:System.Windows.Forms.ContextMenuStrip component, and then add a xref:System.Windows.Forms.ToolStripMenuItem for each operation you want to make available at run time.
-
Set the xref:System.Windows.Forms.TreeNode.ContextMenuStrip%2A property of the appropriate xref:System.Windows.Forms.TreeNode to the shortcut menu you create.
-
When this property is set, the shortcut menu will be displayed when you right-click the node.
The following code example creates a basic xref:System.Windows.Forms.TreeView and xref:System.Windows.Forms.ContextMenuStrip associated with the root xref:System.Windows.Forms.TreeNode of the xref:System.Windows.Forms.TreeView. You will need to customize the menu choices to those that fit the xref:System.Windows.Forms.TreeView you are developing. Additionally, you will want to write code to handle the xref:System.Windows.Forms.ToolStripItem.Click events for these menu items.
