It also demonstrates dynamic item addition and dynamic This code example demonstrates how to handle the Opening event. The Opening event handler examines the ContextMenuStrip.SourceControl and ToolStripItem.OwnerItem properties and adds a ToolStripItem describing the source control. In the example, an Opening event handler populates the menu item collection. The example also shows how to reuse the same ContextMenuStrip for three different controls on the form. The following code example demonstrates how to dynamically add items to a ContextMenuStrip control. You can dynamically populate the menu item collection of a ToolStrip control when the menu opens.
