VB.Net - ContextMenuStrip Control
The ContextMenuStrip control represents a shortcut menu that pops up over controls, usually when you right click them. They appear in context of some specific controls, so are called context menus. For example, Cut, Copy or Paste options.
This control is associated a context menu with other menu items by setting that menu item's ContextMenuStrip property to the ContextMenuStrip control you designed.
Context menu items can also be disabled, hidden or deleted. You can also show a context menu with the help of the Show method of the ContextMenuStrip control.
