Study Notes
Menu
- Menus are used to provide functionalities without cluttering the UI.
- A MenuStrip component can be added to a form by dragging it from the Toolbox.
Building a Menu Strip
- The MenuStrip Designer allows building a menu strip interactively using its design surface.
Multiple Menu Strips
- A form can host one or more menu strips, all of which can be visible at run time.
- A menu strip can be hidden or shown by setting its Visible property.
Main Menu Strip
- A form's MainMenuStrip property specifies which menu strip receives shortcut keys (Alt+...).
- The Windows Forms Designer automatically sets MainMenuStrip in InitializeComponent to the first menu strip dropped onto a form.
Menu Strip Items
- A MenuStrip control can contain zero or more top-level menus via its Items property, which is of type ToolStripItemCollection.
- The Designer automatically adds a ToolStripMenuItem by default.
- Other types of toolstrip items can be added, including ToolStripComboBox, ToolStripTextBox, and ToolStripSeparator.
- Properties of menu strip items include:
- Checked and CheckOnClick to mark an item as chosen and determine whether it can be checked.
- Enabled and Visible to determine whether the item can be chosen or whether it will be shown.
- Image to assign images to strip items.
- MergeAction and MergeIndex for MDI-related properties.
- ShortcutKeys to assign a keyboard shortcut to a menu item.
Menu Item Text
- The Text property specifies the text shown to the user.
- Including an "&" (ampersand) in the Text property underlines the subsequent character and provides a visual cue for keyboard menu navigation via the Alt key.
- TextAlign and TextImageRelation specify text alignment with or without an image.
Context Menu
- Context menus provide a subset of available menu commands specific to the current activity on a form.
- Forms and controls can have at most one context menu each, specified by the ContextMenuStrip property.
Tool Strip
- Tool strips provide quick access to commonly used commands as single-click buttons.
- They are useful when menu items are deeply hidden within a menu strip hierarchy.
