ToolTip.Popup Event

Note: This event is new in the .NET Framework version 2.0.

Occurs before a ToolTip is initially displayed. This is the default event for the ToolTip class.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in

public event PopupEventHandler Popup
/** @event */
public void add_Popup (PopupEventHandler value)

/** @event */
public void remove_Popup (PopupEventHandler value)

JScript supports the use of events, but not the declaration of new ones.

The Popup event is raised whenever a ToolTip is displayed, either through am explicit call to one of the Show methods or when the ToolTip class implicitly displays a ToolTip. This event can be canceled.

Calling properties in this event that cause the underlying window handle to be recreated, such as IsBalloon, will result in an exception being thrown.
