A good tooltip briefly describes unlabeled controls or provides a bit of additional information about labeled controls, when this is useful. It can also help customers navigate the UI by offering additional—not redundant—information about control labels, icons, and links. A tooltip should always add valuable information; use sparingly.
There are two components you can use to display a tooltip:
- Tooltip: A styled tooltip that you can display on a chosen target.
- TooltipHost: A wrapper that automatically shows a tooltip when the wrapped element is hovered or focused.
