ToolTip vs. Popup (WPF Control)

Question

What are the main differences between these WPF elements?
And when should I use ToolTip instead of Popup ?

Answer 1

A ToolTip - a small pop-up window that appears when the user pauses the mouse over the element; The Popup control provides a way to display content in a separate window that floats above the current application window relative to the assigned item or screen coordinate.

A Popup does not open automatically when the mouse moves over its parent. If you want Popup to open automatically, use the ToolTip or ToolTipService .

Answer 2

The previous tooltips in Winforms were overly restrictive in what you could display. That's why people rode on their own. WPF hints let you apply a template view with color, images, formatting, you name it. The days when you roll have basically disappeared; mostly.
