The ShowPeekForm method allows you to programmatically show the Peek Form for the specified button. The Peek Form can also be automatically shown when a button is hovered with the mouse pointer. To do this, use the ShowPeekFormOnItemHover property.
The Peek Form's content can be specified using the QueryPeekFormContent event. If no content is specified, the Peek Form is not shown.
To hide the Peek Form, call the HidePeekForm method.
