Procedura: associare ContextMenuStrip a un controllo
Dopo avere creato controlli e menu di scelta rapida, attenersi alle procedure riportate di seguito per visualizzare un determinato menu di scelta rapida quando l'utente fa clic sul controllo con il pulsante destro del mouse. Queste procedure consentono di associare un ContextMenuStrip a un Windows Form e a un controllo ToolStrip.
Per associare un ContextMenuStrip a un Windows Form
- Impostare la proprietà ContextMenuStrip sul nome del controllo ContextMenuStrip associato.
Per associare un ContextMenuStrip a un controllo ToolStrip
- Impostare la proprietà ContextMenuStrip del controllo sul nome del controllo ContextMenuStrip associato.
Esempio
Nell'esempio di codice riportato di seguito vengono creati un Windows Form e un controllo ToolStrip e a ciascuno di essi viene associato un ContextMenuStrip diverso.
