Appendix B: Additional User Interface Controls
A ToolTip is a small box displayed when the user holds the mouse cursor over a control.
A combo box is like a list box that has been combined with a text box.
Scroll bars provide a visual way to adjust a value within a range of values. These types of controls
display a slider that may be dragged along a track. Visual C# provides a horizontal scroll bar control
named HScrollBar and a vertical scroll bar control named VScrollBar.
A TabControl allows you to create a user interface that is made of multiple pages, with
each page containing its own set of controls. The TabControl appears as a container on a
form, with one or more tabs positioned along its top edge. Each tab represents a different
page, known as a TabPage. When the user clicks a tab, the control displays that page. You
can find the TabControl in the Toolbox, in the Containers group.
A menu system is a collection of commands organized in one or more drop-down menus.
In Visual Studio, the menu designer allows you to visually create a custom menu system
for any form in an application.
