Ejemplos

En el ejemplo de código siguiente se muestra cómo crear objetos DesignerVerb y cómo agregarlos al menú contextual en tiempo de diseño de un componente.The following code example demonstrates how to create DesignerVerb objects and add them to the design-time shortcut menu for a component.

/* This sample demonstrates a designer that adds menu commands
to the design-time shortcut menu for a component.

To test this sample, build the code for the component as a class library,
add the resulting component to the toolbox, open a form in design mode,
and drag the component from the toolbox onto the form.

The component should appear in the component tray beneath the form.
Right-click the component.  The verbs should appear in the shortcut menu.
